Using ammonium thioglycolate, which is a common ingredient in chemical relaxers and perming solutions, can lead to potential dryness and brittleness in the hair. This occurs because ammonium thioglycolate breaks down the bonds in the hair's protein structure, allowing it to be reshaped. However, this process also removes moisture and can disrupt the hair's natural oils, leading to a dry texture and increased brittleness. It's crucial for hair care professionals to inform clients about proper aftercare and hydration techniques to mitigate these side effects.

Other options, such as an oily scalp, itchy scalp, and hair loss, may not be directly associated with the application of ammonium thioglycolate. While these symptoms can occur in certain cases, they are not the most common side effects linked specifically to the use of this chemical. Proper application and following recommended guidelines can help minimize any adverse reactions.
