Does Botox Prevent or Reverse Hair Loss?

Any news on the use of Botox in treating hair loss? I read something a couple years ago about it and saw it advertised recently. Thanks

We addressed a press release we found back in 2009 that Botox was being used to reverse hair loss. Since then, there’s been a pilot study of 50 men, but nothing I can find beyond that.

The rationale for using Botox as a hair loss treatment is that when the muscles are blocked, the blood flow in the scalp increases and bathes the damaged or thinning hair follicles. If this catches on, there could be a rush to get Botox in the scalp by some of the many balding men and women. I do not endorse this treatment at this time without more convincing evidence that there is value in the use of Botox for this purpose.
