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.

HYDR-8 Weightless Repair Oil is a styling treatment and finishing hair oil so we recommend using it on damp hair or dry hair instead of an overnight treatment.

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.

    Great product!

    Used the shampoo and the conditioner too. Have used their other products as well- I was having postpartum hair loss and these products were amazing! Highly recommend! Helped my hair regrow and get thicker and totally reduce and stop the hair loss that was happening. My hair dresser and I think even my doctor noted how healthy my scalp was looking despite all of the hair that had been falling out after I started using these products.
