Less hair fall

Reformulated—thinner product
Ive been using Nioxin shampoo and conditioner for advanced thinning/chemically treated hair for years. The new system's condition is such a disappointment. The consistentency is significantly thinner—like a watered-down version of the old formula. It used to be moisturizing enough for my color-treated & permed hair. This one leaves my hair feeling drier overall and my ends rough. Now, I have to follow up with a hair mask from mid shaft to ends. I will continue using the shampoo, but this conditioner is just such a let down.
I will always buy my products at Ulta
