TLDR Niacin derivatives may increase hair fullness in women with hair loss.
In 2005, a pilot study investigated the effectiveness of topically applied niacin derivatives, specifically octyl nicotinate and tetradecyl nicotinate, in treating female pattern alopecia. The study was double-blinded and placebo-controlled, involving 60 female participants diagnosed with Ludwig types I-III female pattern hair loss. Of these, 40 received the active treatment and 20 were given a placebo. After a treatment period of 6 months, the results indicated a statistically significant increase in hair fullness for those using the niacin derivatives compared to the placebo group, with a P value of 0.04. The study suggested that niacin derivatives could be a beneficial long-term topical treatment for female pattern hair loss and recommended further research to confirm these findings.
