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.
