Hair resists penetration of chemical treatments such as coloring, waving, straightening or similar treatments. Gray hair may sometimes resist the addition of hair color. Some hair textures may not take perms or other chemical treatments. A variety of factors can cause hair to be resistant.
Daily Hair Tip
Whenever possible limit or avoid using a brush on curly tresses. Instead use a widetooth pick or comb with "hair friendly" edges that won't rip or tear fragile curls.
