vitamin E α-tocopherol α-tocopheryl acetate topical application hair growth microcirculation

The study from 1965 examined the impact of topical vitamin E on rabbit hair growth, using α-tocopherol and α-tocopheryl acetate lotions. It found that vitamin E significantly accelerated hair growth, with effects visible after 2 weeks and pronounced after 4 weeks, resulting in up to 2.4 times more growth in treated areas compared to controls. The time to hair growth cessation was reduced from 13 weeks in control areas to 10 weeks in treated areas. Both forms of vitamin E were effective, with α-tocopherol showing a slightly higher immediate effect. The study concluded that vitamin E enhanced hair growth by improving local microcirculation.

research Percutaneous Absorption of Alpha-Tocopheryl Acetate

22 citations, January 1968 in “THE JOURNAL OF VITAMINOLOGY”

The 1968 study by Kamimura and Matsuzawa examined the percutaneous absorption of α-tocopheryl acetate in 7 patients and 14 skin samples, finding it was well absorbed through healthy skin primarily via the epidermis and hair follicles. The compound showed a high affinity for small blood vessels and was notably present in hair papillae shortly after application. While it appeared in sebaceous glands, it was not detected in their immediate environment. The study suggested a potential conversion to α-tocopherol during absorption, though this was not confirmed. The findings indicated that α-tocopheryl acetate could penetrate skin layers more effectively than water-soluble substances, with no absolute barriers to its absorption.
