How Do I Know If My Hair Is Weak?
Weak hair is hair that has lost structural “ingredients” like proteins and lipids and is characterized by a tendency towards hair breakage. The most telltale sign of weak hair is split ends, but excessive tangling, a duller appearance and a rougher-than-normal feel are all signs that hair has been weakened.
