Frequently Asked Questions

GRO Revitalizing Shampoo works for all hair types and textures, especially fine or thin.

GRO Revitalizing Shampoo is formulated without harsh sulfates (no SLS and SLES) and chemicals that strip your hair of its color.

There is no right or wrong answer. It's really a personal question and depends on scalp sebum production (oily or dry) and hair density (thick or thin) as well as hair texture.

    It works!

    I love this shampoo! It actually worked when my hair was shedding. I did also notice less shedding after using the product. I would just like to say be careful while this. I have used it at different times. I got stung by a wasp 2 different times on my head bc of the shampoo. Apparently it’s bc wasps are attracted to citrus smells and the shampoo has a strong citrus smell.

    Nice lathering and results

    I love the shampoo. And the entire line. But, the cap broke immediately. Making it difficult not to lose precious product.
