The shampoo is specifically designed for hair with thinned ends. It may not provide the same benefits for healthy, thick hair without thinning.
Can I use this shampoo with the Ends Filler Concentrate?

The shampoo works well for my thinning ends. It doesn’t leave my hair feeling heavy or greasy. I noticed a visible improvement in texture after a few washes. The Amino Acid blend seems to help with daily wear and tear.
