I have experienced both but I don't really see a difference between both:
Stiff, dry, no shine.
So how can I know if my hair is either dry or protein overloaded? Cause the remedies aren't the same..
Protein products can repair damage and strengthen the hair shaft, but too much protein makes hair brittle and causes breakage. A salon style protein hair mask is formulated to provide the benefits of protein but they usually cost a pretty penny at the salon. Make a protein hair mask at home that works as well or better than one you get from a salon and that is safe for your hair.
