What is not recommended before performing chemical services on hair?

Brushing the hair before performing chemical services is not recommended because it can lead to increased hair damage and discomfort for the client. When hair is brushed aggressively, especially when it is dry or tangled, it can cause breakage or weaken the hair shaft, making it more susceptible to damage during the chemical process.

Additionally, brushing can disrupt the cuticle, the outer protective layer of the hair, thereby affecting how the hair absorbs chemical treatments. It’s essential to maintain the integrity of the hair in preparation for chemical services to ensure optimal results and reduce the risk of adverse reactions.

On the other hand, washing the hair helps to remove product buildup for better chemical penetration; conditioning can provide moisture and protect the hair; and consulting with the client is crucial for discussing their hair history, any allergies, and the desired outcome of the chemical service. All these actions aim to prepare the hair safely and effectively, while brushing does not align with these priorities.
