Some Shampoos & Conditioners change the color of our hair, in my opinion, consult with a Beautician / Costemotoligist and ask them what is the best Shampoo & Conditioner to use... Also, too much Shampooing of our hair is not good for us Also I believe if we go for a long time with no Shampooing of our hair the color grows in more and it tends to get darker so that could be another reason ?
