A Research Article on Formulation and Evaluation of Herbal Shampoo

The goal of this research is to create a herbal shampoo that promotes hair growth and strength without harming or destroying it. The herbs reetha, amla, neem, fenugreek, hibiscus, and shikakai were chosen using a traditional system. Shampoo is used to clean the hair while also conditioning, smoothing, and maintaining hair health, keeping it free of dandruff, filth, grease, and lice. Above all, it is meant to provide safety benefits. Antimicrobial agents can be classed as either bactericidal (killing bacteria) or bacteriostatic (slowing the growth of germs). Antibacterial agents are crucial in the fight against infectious diseases. As a result, we discovered good qualities for herbal shampoo in our study, and we will continue to optimise the benefits of herbal shampoo for human usage as a cosmetic product.

Selective Expansion of Tregs Using the IL-2 Cytokine Antibody Complex Does Not Reverse Established Alopecia Areata in C3H/HeJ Mice.

Alopecia areata (AA) is an autoimmune disease mediated by NKG2D-expressing cytotoxic T lymphocytes destroying hair follicles in the skin. It is one of the most common autoimmune diseases, but there is no effective treatment modality approved by the FDA. Regulatory T cells (Tregs) are crucial for suppressing autoreactive T cells, and in the skin, they promote hair growth by inducing anagen. Based on this, we tested the therapeutic potential of expanded Tregs in AA using the C3H/HeJ mouse model. In mice with AA, NKG2D-expressing CD8 T cells widely infiltrate both haired and hairless skin areas, which have tissue-resident memory T-cell phenotypes. Tregs in the skin express CD25, CTLA-4, GATA-3, and Jagged1 and efficiently proliferate with IL-2 cytokine antibody complex. However, expanding Tregs in the skin did not induce anagen in normal mice, indicating that they are necessary but not sufficient for anagen induction. Also, they fail to suppress autoreactive CD8 T cells in the skin to reverse established AA in C3H/HeJ mice. These results suggest that Treg expansion alone is not sufficient for AA treatment, and combined immunotherapy is required.

Single-cell transcriptomics reveals the natural product Shi-Bi-Man promotes hair regeneration by activating the FGF pathway in dermal papilla cells

BackgroundFinasteride and minoxidil are two commonly used drugs for the treatment of hair loss. However, these two drugs have certain side effects. Thus, the further elucidation of treatments for hair loss, including those using Chinese herbal medicine, remains important clinically. Shi-Bi-Man (SBM) is a hair health supplement that darkens hair and contains ginseng radix, tea polyphenols, polygonum multiflorum, radix angelicae sinensis, aloe, linseed, and green tea extract. PurposeThis study aimed to find potential effective monomer components to promote hair regeneration from SBM and to explore the mechanism of SBM to promote hair regeneration. MethodsSupplementation with the intragastric administration or smear administration of SBM in artificially shaved C57BL/6 mice, observe its hair growth. UPLC/MS and UPLC/LTQ-Orbitrap-MS detect the main components in SBM and the main monomers contained in the skin after smearing, respectively. A network pharmacology study on the main components of SBM and single-cell RNA sequencing was performed to explore the role of SBM for hair regeneration. ResultsSBM significantly induced hair growth compared with a control treatment. TSG and EGCG were the main monomers in the skin after SBM smearing. The results of single-cell sequencing revealed that after SBM treatment, the number of hair follicle stem cells (HFSCs) and dermal papilla cells (DPCs) increased significantly. Cell interactions and volcano dots show that the interaction of the FGF signaling pathway was significantly enhanced, in which Fgf7 expression was especially upregulated in DPCs. In addition, the Wnt signaling pathway also had a partially enhanced effect on the interactions between various cells in the skin. The network pharmacology study showed that the promotion of the FGF and Wnt pathways by SBM was also enriched in alopecia diseases. ConclusionWe report that SBM has a potential effect on the promotion of hair growth by mainly activating the FGF signaling pathway. The use of SBM may be a novel therapeutic option for hair loss.

The effects show that the herbal shampoo has the following properties, such as desirable foaming ability, good cleansing, low surface tension, viscosity and soothing properties. The effects of the evaluation of the herbal shampoo showed higher effects, which is good to use, secure and powerful in treating hair loss.

Lagerstroemia indica extract regulates human hair dermal papilla cell growth and degeneration via modulation of β-catenin, Stat6, and TGF-β signaling pathway.

Lagerstroemia indica (L.indica) is reported to have diverse biological activities including anti-inflammatory, anti-cancer, neuro-regulatory, antidiabetic, and antioxidant activity. The purpose of this study is to examine the potential of hair growth promotion and/or hair loss prevention by L.indica extract. The effects of L.indica on hair growth have been studied in human hair follicle dermal papillary (hHFDP) cells and follicular organ culture ex vivo by cell proliferation assay, PCR, western blot analysis, and reporter gene activity assay. Moreover, a clinical trial was conducted in healthy volunteers. Lagerstroemia indica significantly promoted the proliferation of hHFDP cells, which was associated with increased expression of TCF/LEF, VEGF, and Gli1 mRNA, and inhibition of STAT6 and Smad2 mRNA. Treatment with L.indica also increased the TCF/LEF reporter gene activity but downregulated the SBE- and STAT6-luciferase activities. The expression of total β-catenin, CDK4, and CDK2 were elevated, while that of STAT6 and SMAD2/3 was suppressed upon treatment with L.indica. In human hair follicles organ culture, L.indica significantly inhibited hair follicular degeneration. The clinical trial showed a statistically significant rise in total hair count in test group (n=24) after 24 weeks of applying the hair tonic enriched with L.indica (141.46 ± 21.27 number/cm2 , p < 0.05). We suggest that L.indica extract prevents hair loss as well as stimulate hair growth by regulating the Wnt-β-catenin, JAK3-STAT6, and TGF-β1-Smad signaling pathways, and may be further developed as a novel functional cosmetic for preventing hair loss.

Phytochemical Constitution, Anti-Inflammation, Anti-Androgen, and Hair Growth-Promoting Potential of Shallot (Allium ascalonicum L.) Extract.

In Thai folklore wisdom, shallot (Allium ascalonicum L.) was applied as a traditional herbal medicine for hair growth promotion with no scientific evidence. Androgenetic alopecia (AGA) is a progressive hair loss caused by multiple factors, including androgen hormones, inflammation, and oxidative stress. Conventional medicines (finasteride, dutasteride, corticosteroids, and minoxidil) have been used with limited therapeutic efficacy and unpleasant side effects. In this study, we aimed to give the first estimation of bioactive compounds in shallot extract and evaluate the hair growth-promoting activities regarding anti-inflammatory and gene expression modulation involving androgen, Wnt/β-catenin, sonic hedgehog, and angiogenesis pathways. The results reveal that phenolic compounds (quercetin, rosmarinic, and p-coumaric acids) are the major constituents of the methanolic shallot extract. Compared with the lipopolysaccharide-stimulated control group (2.68 ± 0.13 µM), nitric oxide production was remarkably diminished by shallot extract (0.55 ± 0.06 µM). Shallot extract improves hair growth promotion activity, as reflected by the downregulation of the androgen gene expression (SRD5A1 and SRD5A2) and the upregulation of the genes associated with Wnt/β-catenin (CTNNB1), sonic hedgehog (SHH, SMO, and GIL1), and angiogenesis (VEGF) pathways. These findings disclose the new insights of shallot extract on hair growth promotions. Shallot extract could be further developed as nutraceutical, nutricosmetic, and cosmeceutical preparations for AGA treatment.

Exosome therapy in hair regeneration: A literature review of the evidence, challenges, and future opportunities.

Alopecia is a common chief complaintand is challenging to treat. As such, regenerative treatments to promote hair growth are an emergingarea of research. Exosomes, which are extracellular vesicles involved in cell communication, homeostasis, differentiation, and organogenesis, have been shown to play a central role in hair morphogenesis and regeneration with potential for use as alopecia treatment. This review summarizes and assesses the body of literature surrounding exosomes as regenerative therapeutics for alopecia and identifies areas for improvement in future research. A review was conducted using a comprehensive list of keywords including "exosome," "alopecia," and "hair loss" on PubMed, EMBASE, and Google Scholar databases published from inception to February 2022. Reference lists of identified articles were included. 47studies were included. Clinical trial databases were searched using the term "exosome"; however, no trials relevant to hair growth were identified. Our updated and comprehensive review details the history of exosome use in medicine, postulated underlying mechanisms in treating hair loss, and current clinical studies. Preclinical studies demonstrate clear benefits of exosome therapeutics in regenerative medicine and for hair loss treatment. Clinical trials demonstrate safety of exosome use in medicine, but data showing efficacy and safety of exosome therapy for alopecia are lacking. We identified several gaps in knowledge required for effective clinical translation including safety, exosome source, and optimal treatment delivery mechanism and dosage. Exosomes are on the horizon as an exciting therapeutic for the treatment of alopecia. Further studies and clinical trials are required.

However, the complex active substances of poring also hinder the research of P. umbellatus to some extent, and the mechanism of action and potential synergistic or antagonistic effect of the mixture of various active ingredients have not been clearly analyzed. How to use the bioactivity-guided separation strategy to identify more bioactive components and analyze the molecular mechanism of the main active components have become the main problems of P. umbellatus research, but also provides a direction for the further study of it.

Sodium pentaborate pentahydrate promotes hair growth through the Wnt/β-catenin pathway and growth factors

BackgroundBoron (B) is an element involved in many physiological processes in humans and accelerates wound healing and increases angiogenesis. This study aimed to evaluate the possible effects of sodium pentaborate pentahydrate (NaB) on hair growth and reveal its effects on Wnt-1, β-catenin, vascular endothelial growth factor (VEGF), platelet-derived growth factor (PDGF), and transforming growth factor-β1 (TGF-β1) signaling pathways, which are important molecular mechanisms involved in hair growth. MethodsThirty-five Sprague-Dawley/Wistar albino rats were randomly divided into five groups: non-shaved control, shaved control, NaB 1 mg (shaved + NaB 1 mg elemental B/kg CA), NaB 2 mg (shaved + NaB 2 mg elemental B/kg CA), and NaB 4 mg (shaved + NaB 4 mg elemental B/kg CA). Hair density was measured using the trichoscopy method. Dorsal skin samples were examined histopathologically at the end of the 42nd day, and follicle count, follicle diameter, and subcutaneous tissue thickness were recorded. Wnt-1, β-catenin, PDGF, VEGF, TGF-β1, and collagen I levels were analyzed with the Western blot method. ResultsIn trichoscopy measurements, hair density increased in the NaB 4 mg group (90.9%). In histopathological examination, anagen follicles were observed to increase in the NaB 1 mg and 2 mg groups (p < 0.05). Follicle diameter increased in all NaB groups (p < 0.05). The Wnt-1, β-catenin, PDGF, VEGF, TGF-β1, and collagen I level increased in the NaB 1 mg and 2 mg groups (p < 0.05), but they were similar in the NaB 4 mg group compared to the control groups (p > 0.05). ConclusionNaB 1 and 2 mg B/kg supplementation induces the anagen phase in rats via Wnt-1, β-catenin, VEGF, PDGF, and TGF-β1 signaling pathways. NaB 4 mg B/kg suppresses these pathways and adversely affects hair growth.

Co-delivery of bioactive peptides by nanoliposomes for promotion of hair growth

Hair loss is a benign, treatable and chronic disorder which will cause the worse life quality of patients over time. Bioactive peptides can be used for hair growth promotion with many advantages such as low toxicity, high selectivity and targeted specificity. However, the bioactive peptides have limited efficacy alone and difficulty in transdermal absorption into the hair growth targeted cells - dermal papilla cells (DPCs). We developed nanoliposomes loaded with copper peptide, acetyl tetrapeptide-3 and myristoyl pentapeptide-4 (CAM-NLPs) simultaneously to achieve a synergistic effect of multiple bioactive peptides combination, improve their delivery efficiency for promoting hair growth. The CAM-NLPs exhibited uniform particle sizes, high encapsulation efficiency and loading capacity for the bioactive peptides. In vitro experiments revealed that the CAM-NLPs remarkably promoted the proliferation of immortalized human keratinocytes (HaCaT) and human dermal papilla cells (HDPCs), boosted the migration ability of HDPCs and increased the secretion of collagen III, vascular endothelial growth factor (VEGF) and basic fibroblast growth factor (bFGF) from HDPCs. Furthermore, it was revealed that CAM-NLPs promoted hair growth by up-regulating the expression of VEGF and β-catenin and down-regulating the expression of transforming growth factor-β1 in the skin of C57BL/6 mice in vivo via Western blotting assay. In summary, CAM-NLPs are effective transdermal co-delivery nanocarrier for alleviating hair loss in androgenetic alopecia with hair growth promotion, high safety and great potential.

Mangifera Indica leaf extracts promote hair growth via activation of Wnt signaling pathway in human dermal papilla cells

ABSTRACT The crosstalk between androgens and Wnt signaling pathways is critical in the hair growth cycle. Therefore, natural products that target these two pathways for the inhibition of hair loss are sought after. In this study, we investigated the effect of water extracts of Mangifera indica leaves (WEML) on hair growth. WEML treatment significantly reduced the expression levels of both dickkopf-1 (DKK1) and type 2 5α-reductase (SRD5A2) involved in Wnt signal suppression activity and dihydrotestosterone (DHT) synthesis, respectively, in human follicle dermal papilla cells (HFDP). In addition, WEML treatment effectively upregulated Wnt target genes and downregulated DKK1 expression that was increased by DHT treatment. Degranulation analysis in rat basophilic leukemia mast cell line (RBL-2H3) using β-hexosaminidase release assay confirmed that WEML did not exhibit allergenic activity. Furthermore, hair growth was significantly enhanced in in vivo mice model treated with WEML. These results suggest that M. indica leave extract contains bioactive materials that can be used to treat hair loss.

Hair growth-promoting effects of Camellia seed cake extract in human dermal papilla cells and C57BL/6 mice.

Camellia seed cake is a by-product of Camellia oleifera Abel seed after oil extraction. Washing hair with Camellia seed cake extract is a traditional Chinese custom that has lasted for over one thousand years. However, the hair growth-promoting effects of Camellia seed cake extract were not investigated so far. This work examined the effects of de-saponinated Camellia seed cake extracts (DS-CSE) on hair growth, using in vitro and in vivo models. The studies on cell proliferation, cell cycle regulation, and K+ channels activation effects of DS-CSE were performed on human dermal papilla cells (DPCs). Relative expression of insulin-like growth factor-1 (IGF-1), vascular endothelial growth factor (VEGF), hepatocyte growth factor (HGF), and transforming growth factor-β (TGF-β1) in DPCs was determined by RT-PCR. Relative expression of ERK and AKT was determined by Western blot analysis. Hair growth-promoting effects were also measured in C57BL/6J mice model. DS-CSE treatment significantly proliferated DPCs, relating to the increased proportion of DPCs in S and G2 /M phases, the activation of potassium channels and the promoted phosphorylation of ERK and AKT in DPCs. DS-CSE treatment also significantly upregulated the mRNA levels of HGF, VEGF and IGF-1, and downregulated the mRNA level of TGF-β1. Topical application of DS-CSE promoted hair growth on shaven back mice and also upregulated the expression of VEGF in mice. Our results demonstrated that DS-CSE exerts a hair growth-promoting effect in vitro and in vivo by proliferating DPCs through the ERK and AKT signaling pathways and regulating the expression of growth factors.

5-Bromo-3,4-dihydroxybenzaldehyde Promotes Hair Growth through Activation of Wnt/β-Catenin and Autophagy Pathways and Inhibition of TGF-β Pathways in Dermal Papilla Cells.

Various studies addressing the increasing problem of hair loss, using natural products with few side effects, have been conducted. 5-bromo-3,4-dihydroxybenzaldehyde (BDB) exhibited anti-inflammatory effects in mouse models of atopic dermatitis and inhibited UVB-induced oxidative stress in keratinocytes. Here, we investigated its stimulating effect and the underlying mechanism of action on hair growth using rat vibrissa follicles and dermal papilla cells (DPCs), required for the regulation of hair cycle and length. BDB increased the length of hair fibers in rat vibrissa follicles and the proliferation of DPCs, along with causing changes in the levels of cell cycle-related proteins. We investigated whether BDB could trigger anagen-activating signaling pathways, such as the Wnt/β-catenin pathway and autophagy in DPCs. BDB induces activation of the Wnt/β-catenin pathway through the phosphorylation of GSG3β and β-catenin. BDB increased the levels of autophagic vacuoles and autophagy regulatory proteins Atg7, Atg5, Atg16L, and LC3B. We also investigated whether BDB inhibits the TGF-β pathway, which promotes transition to the catagen phase. BDB inhibited the phosphorylation of Smad2 induced by TGF-β1. Thus, BDB can promote hair growth by modulating anagen signaling by activating Wnt/β-catenin and autophagy pathways and inhibiting the TGF-β pathway in DPCs.

Hair growth-promoting effects of Sargassum glaucescens oligosaccharides extracts

Background: Brown algae have been used as food and traditional Chinese medicine for thousands of years and it is known to contain a bioactive component - fucoidan. However, little is known about the effect of fucoidan on cell differentiation and proliferation, particularly in topical application. Given that, this study focused on investigating the effect of different extraction methods of fucoidans on the promotion of human hair growth ability.Methods: Fucoidans from Sargassum glaucescens were extracted by a combination of microwave-assisted high-pressure water or subcritical water. Different molecular weight fractions of fucoidan were separated. The effect of these fractions on the proliferation and hair growth-related genes expression on hair follicle dermal papilla cells (HFDPC) was investigated. Mice models and ex vivo hair follicle culture assays were used to determine the efficacy.Significant Findings: Sargassum glaucescens fucoidan extracts higher than 1 KDa molecular weight demonstrated hair growth-promoting ability. The oligo-fucoidan was more effective in enhancing hair follicle cell proliferation. The effects of fucoidans on the proliferation of HFPDC correlated with IGF-1 and LEF-1 gene expressions. Hair growth-promoting activity was observed in mice models after being treated with Sargassum glaucescens fucoidan extracts. Thus, fucoidan could be a potential topical medicine in alopecia treatment.

Sustained delivery of rhMG53 promotes diabetic wound healing and hair follicle development.

MG53 is an essential component of the cell membrane repair machinery, participating in the healing of dermal wounds. Here we develop a novel delivery system using recombinant human MG53 (rhMG53) protein and a reactive oxygen species (ROS)-scavenging gel to treat diabetic wounds. Mice with ablation of MG53 display defective hair follicle structure, and topical application of rhMG53 can promote hair growth in the mg53−/− mice. Cell lineage tracing studies reveal a physiological function of MG53 in modulating the proliferation of hair follicle stem cells (HFSCs). We find that rhMG53 protects HFSCs from oxidative stress-induced apoptosis and stimulates differentiation of HSFCs into keratinocytes. The cytoprotective function of MG53 is mediated by STATs and MAPK signaling in HFSCs. The thermosensitive ROS-scavenging gel encapsulated with rhMG53 allows for sustained release of rhMG53 and promotes healing of chronic cutaneous wounds and hair follicle development in the db/db mice. These findings support the potential therapeutic value of using rhMG53 in combination with ROS-scavenging gel to treat diabetic wounds.
