Notes
grade-b Notable Very High See all 8 studies
Topical application of Minoxidil (oral administration as well, but that is associated with more side-effects) appears to be highly effective in increasing the rate of hair regrowth and can reverse hair loss associated with non-androgenic hair loss (bald patch, rather than a receding hair line which is related to androgens)
grade-c Minor - See study
One study noted that 100mg of mixed tocopherol was able to promote hair growth in persons with alopecia (androgen dependence not specified) relative to placebo.
grade-d Minor - See study
May induce hair growth when topically applied
