Hi Dr. Rassman,
What is your take on using capsaicin for hairloss? It’s my belief that Zhang Guang 101, a Chinese “herbal” product that is popular overseas, contains only capsaicin as its active ingredient. Having used a few bottles myself, I’m fairly certain that this simple molecule found in chili peppers is responsible for any hair growth effects that the product claims. I’ve only been using it for a couple weeks, so I can’t give a definitive testimonial. There has been research done on the effect of capsaicin on hair growth. It supposedly promotes the release of IGF-1, which is crucial for hair growth. It also stimulates pain receptors and releases substance P. Can you take a look and tell me what you think? Thanks.

Administration of capsaicin and isoflavone promotes hair growth by increasing insulin-like growth factor-I production in mice and in humans with alopecia

From the article:
“These observations strongly suggested that combined administration of capsaicin and isoflavone might increase IGF-I production in hair follicles in the skin, thereby promoting hair growth.”

Capsaicin is found in chili peppers and even in pepper spray. I don’t have any experience with this, though I read the article and will wait to see if it may become a treatment modality. I’m not opposed to new treatments by any means, but I will need to see actual proof before I throw my support behind it. At any rate, I’d think it would cause incredible tingling in your scalp, just as eating a very spicy pepper can numb your lips.
