Frequently Asked Questions
How long does it take to see results with GRO Hair Serum?

With consistent daily use, most people see results from GRO Hair Serum within 3–4 months.

Will GRO Hair Serum make my hair greasy?

No. GRO Hair Serum is water-based and fast-absorbing, so it won’t leave your hair feeling greasy or weighed down.

What happens if I stop using GRO Hair Serum?

Hair Wellness® is an ongoing journey. If you stop using GRO Hair Serum, you may notice your hair gradually return to its natural state within a few months.

Which hair type is this shampoo and conditioner best for?

GRO Revitalizing Shampoo & Conditioner work for all hair types and textures, including fine or thinning.

Will the Baby Hair Strengthen & Style Wand make my baby hairs feel crunchy or stiff?

No. The lightweight gel-cream texture delivers flexible hold, not a hard cast — so baby hairs stay smooth, touchable and non-crunchy.
