What type of hair is typically resistant to color treatment?

Coarse hair is typically resistant to color treatment due to its thicker cuticle layer, which can make it more challenging for color molecules to penetrate. The structural integrity and larger diameter of coarse hair can result in less porosity, meaning it does not absorb color as readily as finer or thinner hair types. This resistance can lead to uneven color results or a longer processing time when applying hair color.

Understanding the characteristics of different hair types helps in tailoring color treatments effectively, ensuring that stylists can select appropriate products and techniques for optimal results.
