Milady Chemical Texture Services Practice Exam

Over-processing during a chemical service significantly impacts the health of the hair, predominantly leading to breakage and extreme dryness. When the hair is subjected to chemical treatments, such as relaxers or permanent waves, the hair's protein structure can be altered or damaged if the chemicals are left on for too long or if the hair is repeatedly processed. This damage compromises the hair's integrity, making it weak and brittle.

As a result, the cuticle, which is the outer protective layer of the hair, can become lifted or stripped away, further exposing the inner layers to environmental factors and leading to moisture loss. Consequently, the hair becomes dry, lacks elasticity, and is more prone to breakage. This condition is often irreversible without significant trimming and treatment, emphasizing the importance of proper technique and timing in chemical services to maintain hair health.
