What should be avoided to prevent damage during perming?

To prevent damage during the perming process, it is essential to avoid over-processing with heat. When excessive heat is applied during perming, it can lead to the hair becoming overly dry, brittle, and may even result in irreparable damage. The chemical reactions that occur during perming require specific temperatures to achieve the desired curl without harming the hair structure. Overheating can compromise the integrity of the hair cuticle and cortex, leading to breakage or loss of elasticity.

In contrast, using a conditioning treatment, testing the hair's elasticity, and conducting a strand test are all beneficial practices that help assess the hair's condition and ensure optimal results without causing damage. Conditioning treatments nourish and prepare the hair for chemical processes, while testing elasticity helps determine how the hair will respond to perm solutions. A strand test is a safe method to preview the results of a perm on a small section and gauge the hair's reaction to the chemicals. These practices are aimed at preserving hair health during the perming process.
