3. Chemically Treated?
Clarifying chemically treated hair is even more vital, as this hair is more porous than most. It is also important to find the proper balance between protein and moisture-based shampoos.
4. It Expires!
I know you probably don’t want to hear this, but that one kind that you got on sale for 80% off so you purchased 20 bottles of it back in 2007? It’s time to toss it. If you are a product junkie and collect shampoo make sure you are keeping track of their expiration dates. It won’t make you sick per se, like rotten milk, but it won’t have the same benefits as a fresh bottle.
5. Not Too Much
There is such thing as too much shampoo. A quarter size should do the trick, and definitely not much more than that. Too much product will create an unnecessary amount of lather, and will take away from the massaging of the scalp and hair.
