Noun: Botox treatment on hair, also known as a hair botox, is a non-surgical cosmetic procedure that involves injecting a neurotoxin into the hair shafts to relax and smooth them.
Hair botox is an increasingly popular treatment for reducing frizz, improving shine, and making hair more manageable. It is particularly beneficial for those with damaged or dry hair, as it helps to repair and strengthen the hair shafts. The procedure was first developed in Brazil in the early 2000s, and has since gained popularity worldwide.
