TLDR Botulinum toxin injections can reduce hair loss and stimulate new hair growth in some men with male pattern baldness.

In a study conducted 10 years ago, 50 male subjects aged between 19 and 57 years with Norwood/Hamilton ratings of II to IV were treated with peripheral scalp injections of botulinum toxin-A (BTX-A) to determine if it would reduce hair loss or stimulate hair growth. The 60-week study showed a response rate of 75% with 40 subjects completing the study. The mean hair counts for the entire group showed a statistically significant increase of 18% between baseline and week 48, similar to the results reported with Propecia®. Hair loss was reduced by 39%. The study concluded that strategically placed BTX-A injections appear able to indirectly modify scalp physiology, resulting in reduced hair loss and new hair growth in some men with androgenetic alopecia.

in Treatment 28 upvotes 1 year ago

The conversation discusses the delay in the release of a new hair loss treatment, Pyrilutamide, and speculates on potential safety concerns as a reason for the delay. It also mentions GT20029 as another future treatment option, with a release at least five years away, and touches on the avoidance of research chemicals due to uncertainty about their authenticity.

community If Minoxidil Beards are permanent, why should Finasteride be unable to keep Minoxidil Gains on the scalp?

in Minoxidil 104 upvotes 1 year ago

Whether Finasteride can keep alive the hair gained by Minoxidil after quitting it, and why beard hairs are not as susceptible to miniaturization. It is suggested that scalp hair may be dependent on Minoxidil and that DHT could be countered with Finasteride to some extent, but there is no definitive data proving this.
