The Hair Stimulator is a shampoo from the new, fresh & hip brand Hims. The branding is really on point but let’s dig into the ingredients. Biotin, nettle leaf, tea tree and salicylic acid are the noteables. There’s some evidence to indicate that biotin and salicylic acid reduce scalp DHT levels. Additionally, Hims offers a comprehensive hair loss kit (includes the shampoo) for about $40 bucks a month that gets you hair loss prevention on multiple fronts.
Researchers from South Korea have identified a new peptide called PTD-DBM which exhibits wound healing and hair regeneration effects in preclinical studies. The research is being led by Professor Kang-Yell Choi of Yonsei University. Choi’s team identified the peptide PTD-DBM which targets a protein called CXXC5. The interaction of these two proteins leads to stimulation of the Wnt pathway, which then initiates hair follicle neogenesis. Choi hopes to develop this peptide further into a potential hair growth drug candidate. A research paper about these findings was put out by the team earlier this year.

Dupilumab is FDA approved for treating eczema aka atopic dermatitis and sold under the brand name Dupixent. As the story goes, a patient with alopecia totalis (a form of areata which leaves a person’s head completely bald) was being treated for eczema by the drug Dupixent. After 6 weeks the patient first began to notice progress in terms of hair growth and at 7 months she had noticeable pigmented hair growth on her scalp. Notably, the patient stopped taking the dupilumab for a period of time and noticed her growth subsided; when she began taking the drug again the hair improved once more. This provides another useful therapy option for patients seeking treatment for AA. One would imagine a topical version would be worthwhile to investigate.
