Let me start by saying that I have really thick hair. Well after Botox and 3 months went by I started experiencing hair loss.

Thank you for your question.  Hair loss is often due to a multitude of factors with stress, temporary fluctuations in hormones, and increasing age being some of the more common.  I do not feel that Botox likely contributed to your hair loss as it is not a reported side effect from studies.  I am happy to hear that your hair has been growing back, however.  

Botox is not known to cause hair loss.  I am not sure why it started falling out but even stress alone can cause hair loss.  I am happy for you that your hair is growing back.  Best, Dr. Green

Thank you for your question.Botox is injected 3-4 times a year in the underarms for patients with hyperhidrosis and i have never heard of a patient who complained or was happy that there was hair loss in the underarms. I have done those injections for years and have a huge hyperhidrosis practice.I also inject 200 units of Botox in the scalp for patients with craniofacial hyperhidrosis and have never had a patient report hair loss from these repeated injections, i.e., every 3-4 months. I have also never had a patient report hair loss after cosmetic Botox injections.BestDr. Karamanoukian
