Frequently Asked Questions

Like any good wellness routine, results require effort to be maintained. If you stop using GRO Hair Serum, you'll see hair return to its natural state within a few months of discontinuing use.

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.

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

    Loving what it is doing for my hair!

    I just recently found this product at Sephora and started using it. I love what it has done for my thinning hair! It smells great, has helped make my hair soft and healthy feeling again, and I am noticing a difference in the fullness too!
