  1. Start by applying GRO Hair Serum to the scalp. Fill one dropper and apply to areas where you’re seeing thinning or all over the scalp to promote hair wellness.
  2. Massage in. Do not rinse. Use daily to see results in as soon as 90 days.**
  3. After styling, use HYDR-8 Weightless Repair Oil from mid-lengths to ends. Remember, a little goes a long way, so it’s important to really disperse the product evenly onto your hands. It leaves hair with a ton of shine — but without the weight — for glossy, thicker-looking hair from root to tip.

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.
