What type of hair is generally more resistant to heat damage?

1. Fine hair

2. Medium hair

3. Coarse hair

4. Textured hair

The correct answer is: Coarse hair

Coarse hair is generally more resistant to heat damage due to its thicker and denser structure. The cuticle layer of coarse hair is also more robust, which provides better protection against high temperatures and reduces the likelihood of moisture loss. This structural integrity helps coarse hair withstand the stress caused by styling tools such as flat irons and curling wands. In contrast, fine hair, which has a smaller diameter, is more susceptible to heat damage because it can easily become over-processed and lose moisture when exposed to high temperatures. Medium hair falls somewhere in between, being more balanced but still vulnerable to damage under extreme heat. Textured hair, which may have curls or waves, can also be affected by heat but often has a more complex structure that can vary in resilience depending on the specific characteristics of the individual’s hair.
