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.
When applied daily, expect to see results from GRO Hair Serum in 3-4 months. Our best advice: Consistency is key. With HYDR-8 Weightless Repair Oil, you’ll see instant results after your first use.
Apply a quarter-size amount each of GRO Revitalizing Shampoo and Conditioner. Use one dropper of GRO Hair Serum daily to see results in as soon as 90 days.** A little goes a long way with HYDR-8 Weightless Repair Oil, so always start with less and add more.

I did a rough chop on my hair in Feb.'23.to start over due to damage,stress&hoping to jumpstart my regrowth journey.As we all know growth pattern changes as we get older(I am 48)and my hair just wasn't doing the same things it was doing in my 20's.The pics are from November when i started my first bottle(black&white)and January while on my second bottle.It is a process but I have had some success.
