Frequently Asked Questions

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.

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.

    This makes my hair so full looking. I love the way it feels. I went back to redken when I ran out because this is pricey and my hair felt limp and thin again. This product works for me. It’s pricey so I wait until I can get 20% off.
