Effects of Hair Essence Containing Vitamin E, Vitamin A, and Phytantriol on Hair Quality

Abstract

Purpose: This study examined the effect of a hair essence containing α-tocopheryl acetate, retinyl palmitate, and phytantriol (TRP-hair essence) on damaged hair and hair quality characteristics such as hair volume and gloss.Methods: The TRP-hair essence containing 0.01% (w/w) each of α-tocopheryl acetate (vitamin E), retinyl palmitate (vitamin A), and phytantriol was prepared. The effect of the TRP-hair essence on damaged hair was analyzed using a scanning electron microscope; its impact on hair volume and gloss was confirmed using a high-resolution digital camera. Furthermore, a sensory evaluation was used to determine satisfaction after using the TRP-hair essence.Results: The cuticle of the hair that had been damaged because of chemical treatment improved by 19.8% (<i>p</i><0.05) following only a single round of the TRP-hair essence treatment. Hair volume and gloss significantly increased immediately and 24 hours after using the TRP-hair essence (<i>p</i><0.05). There was substantial satisfaction in terms of the sensory evaluation of directly using the TRP-hair essence on human hair.Conclusion: Using the TRP-hair essence effectively recovered the damaged hair and improved its quality characteristics such as hair volume and gloss, resulting in high satisfaction with use.
