Question

1. what materials should combs be made of if they are being used in thermal styling? 100. why should flat irons coated with titanium be avoided for fine, damaged, or fragile hair?

Explanation:

1. Combs for thermal styling should be made of heat - resistant materials like ceramic, tourmaline, or heat - treated plastic to withstand high temperatures without melting or releasing harmful chemicals, and to glide smoothly through hair.
2. Titanium - coated flat irons can be too harsh for fine, damaged, or fragile hair as titanium conducts heat quickly and can cause over - heating and further damage to such delicate hair types.

Answer:

1. Heat - resistant materials such as ceramic, tourmaline, or heat - treated plastic.
2. Because they can over - heat and further damage fine, damaged, or fragile hair due to fast heat conduction.
