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.

    My hair is thicker around my edges and is growing faster all over. I'm happy with the results and will continue to use.

    Love it

    My hair always improves in strength and volume if i use daily

    Unfortunately the cost makes it difficult for me to buy it all the time

    But it gives my hair a boost when I order it and helps with hair growth

    Good purchase

    I’ve been buying the GRO hair serum for over a year now. My hairdresser says my hair feels healthy and soft but I’m not sure if it’s the serum or the shampoo/conditioner that I’m using….. However I keep buying the serum because I like to think it’s keeping my hair growing.

    Fantastic results!

    I’ve been using this growth serum for a year now. After a little more than three months, noticed a definite decrease in shedding and began seeing more new growth. After five months my shedding greatly reduced and I had continued new hair growth.!! Now at the one year mark my hair definitely feels fuller, thicker and healthier! I also use the matching shampoo and conditioner. I’m so satisfied and encouraged with these products and will continue with my subscription plan! I definitely recommend them, and would probably say have patience and stick with it as I did to see great results!
