Question: 1 / 400

What is the effect of heat damage on hair?

Increased moisture retention

Smoother texture

Frizz and split ends

The effect of heat damage on hair primarily manifests as frizz and split ends. When hair is exposed to high temperatures from styling tools, the protective cuticle layer can become compromised. This damage makes hair more porous and less able to retain moisture, leading to dryness. As a result, hair strands may become rough and frizzy due to the lack of moisture and the inability to effectively align the hair cuticles.

Additionally, as the hair becomes weaker, it is more prone to splitting, which further contributes to a damaged appearance. Unlike moisture retention, smoother texture, or enhanced shine, which are benefits usually sought after in hair care, heat damage produces adverse effects that ultimately degrade hair quality. This understanding underscores the importance of using heat protectant products and keeping heat exposure to a minimum during styling to maintain healthy hair.
