Have you ever had a shampoo not produce similar results with continued use?
My suggestion…switch it up!
It’s completely natural for our body’s to shift and alter with age and hormonal change. As a child, I was not allergic to cats. With age, I have developed strong allergic reactions to cat.
I am not implying a developed allergy to your shampoo and conditioner, but what once used to work may not work anymore. Think of it this way, could you survive on the same food every day? Maybe, but our bodies are better working machines with a variety of food to provide various nutrients and minerals.
Since I color my hair regularly, I use a reparative shampoo and conditioner. I also have hard water, a blonde life, color protect and a strengthening shampoo and conditioner. I constantly alternate to keep my hair full with the nutrients it needs. (Keratin, protein and etc.)
