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.

Use a generous amount of GRO Scalp Detoxifying Serum to cover the scalp. Apply a quarter-size amount each of GRO Revitalizing Shampoo and Conditioner. Use one dropper of GRO Hair Serum daily.

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.

    Wonderful!

    I truly love this shampoo and conditioner! The smell is lovely, gentle and not overpowering, and it makes my hair shiny and full and more manageable . Hopefully it is helping to grow new hair too, but I honestly haven't used it consistently enough yet to tell.

    It’s special care.

    My hair type is dry and damaged. Those products may use better every day but I use it as special care 2 or 3 times a week. I loved smell or condition next day.
