What is the main concern when applying a perm to fragile hair?

The main concern when applying a perm to fragile hair is hair breakage. This is because fragile hair is already weakened and more susceptible to damage from chemical processes. A perm involves using strong chemicals that alter the structure of the hair to create curls or waves. When fragile hair is subjected to these chemicals, it may not be able to withstand the stress of the perming process, leading to breakage.

Clients with fragile hair often have underlying issues such as over-processing, environmental damage, or inadequate moisture, which can exacerbate the risk of breakage during and after the perm. Therefore, careful consideration and possibly alternative methods should be discussed with clients who have fragile hair to ensure their hair remains healthy and intact.
