Effectiveness of luliconazole vs ketoconazole topical formulation in reversing damaged hair cuticle

Abstract

Azole antifungal agents are effective agents for treating scalp ailments such as seborrheic dermatitis. Luliconazole (LZ) is a new azole with unique effects against clinically important dermatomycotic fungi. This study examines the impact of different topical formulation of Luliconazole vs Ketoconazole (KZ) on damaged hair cuticle repair after 5 and 10 washes, using SEM images and sensory Analysis.In this in-vitro study,twelve damaged hair tresses were divided into two groups, and treated with LZ and KZ formulations. Both groups underwent pretreatment with 20% Sodium Laureth sulfate (SLES) and damage induction using 9% HO and 20% ammonium solution, followed by respective LZ (Lupizol ZS, manufactured by Lupin Ltd, India) and KZ therapies. SEM imaging and expert sensory analysis were conducted at baseline, after 5, and 10 washes to evaluate surface characterization like cuticle upliftment, smoothness, and softness.After five washes, LZ-treated hair exhibited smooth, intact cuticles with no upliftment, improving to grade 1 cuticle damage. In contrast, KZ-treated hair continued to show substantial upliftment without damage grade improvement. After ten washes, LZ maintained grade 1 damage and 0 µm upliftment, while KZ-treated strands persisted in showing considerable cuticular distress. Sensory analysis supported these results, with LZ improving hair smoothness and softness by 2.42x and 2.72x respectively, after ten washes, significantly outperforming KZ. Visually, LZ-treated hair appeared smoother and healthier, indicating its greater effectiveness in enhancing hair integrity post-washing.The botanical conditioner-based formulation of LZ is more efficacious in enhancing hair integrity post-washing compared to the Ketoconazole formulation. Well-controlled human studies are required to further establish the clinical effects on human participants.
