Effect of Topical Application of Vitamin E on the Hair Growth of Rabbits

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.
