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.

    Hair Saver! Real Results in a Few Months

    I want to start by saying that in 2024, I was sick a lot and had to take antibiotics three times throughout the year. By the end of summer, my hair started falling out at an alarming rate—every time I brushed it, there was hair everywhere, and washing my hair was even worse. My hair lost a lot of its thickness in just a few months. I regret not taking pictures of how much hair was left on my brush. Now, about this serum—it actually works! I’ve grown a lot of new hair, and now I have little baby hairs sticking out all over the place. Even my hairstylist noticed and said that I have a ton of new hair coming in. My hair loss has significantly decreased, and I can feel more volume at the roots. I noticed results within a month when my hair started shedding less. This product is worth every dollar!

    I think it's helping!

    My hair feels more volumnous and I feel like I am losing less hair with each shower. I should have taken a before & after but I feel like there is a difference in the density. Don't love the smell of the serum but the Shampoo and Conditioner are great! I also love the gummy supplements!
