Which chemical in hair relaxers can cause damage if misused?

Ammonium thioglycolate is a common ingredient in hair relaxers that can lead to damage if not used properly. This chemical functions as a reducing agent that breaks down the disulfide bonds in the hair, allowing it to be reshaped into a straighter appearance. However, if misapplied or left on the hair for too long, it can result in excessive hair breakage, dryness, and even scalp irritation.

Proper application technique, including adhering to manufacturer guidelines regarding timing and testing the hair's condition before processing, is crucial to minimize adverse effects. Understanding the potency and potential risks associated with ammonium thioglycolate is essential for anyone practicing cosmetology, as it allows for safer and more effective hair relaxation services.
