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.

The HYDR-8 Leave-In Conditioner provides heat protection up to 450 degrees Fahrenheit.

No, we don’t recommend using this mask overnight. Leaving the hair mask on longer than 5 minutes can provide some additional conditioning benefits, but we recommend using no longer than 10 minutes.

    I had a few bald spots, and I was losing my hair very quickly, and it was thinning. This product has helped my hair grow so much.

    Versatile

    I absolutely love that this product is so versatile. You can spray in and let air dry, blow dry, or even follow up with a heat tool. I love that it doubles as a heat protectant. Most products I’ve used as a leave in conditioner do not have that so I have to double up on products and having fine hair only weighs it down causing my hair to look flat and lifeless. The scent is nice and does fade over time which is ok because it may come off strongly at first.
