Coarse hair is known for its thicker and stronger strand structure, which makes it more resistant to color changes compared to the other hair types. The larger diameter of coarse hair allows it to hold hair color pigments more effectively, meaning that it often requires more processing time and may not absorb color treatments as readily as finer hair types.

In contrast, fine hair, with its smaller diameter, can be more porous and may absorb color faster but is also more prone to damage and fading. Medium hair tends to have a balance between the two but typically does not demonstrate the same level of resistance to color changes as coarse hair. Normal hair is a descriptor of hair that is neither too oily nor too dry, and while its characteristics may be somewhat balanced, it doesn't have the structural resilience of coarse hair in relation to holding color. Thus, coarse hair is recognized as the most resistant to color changes, making it the correct choice.
