Apply RE:YOU Hair Serum once daily to a clean, dry scalp. Part your hair to expose areas of concern, such as the hairline, part line, or crown, then apply 1-2 full droppers directly to the scalp. Gently massage the serum into the scalp for about 30 seconds until absorbed. For best results, use consistently as part of your daily routine. The lightweight, non-sticky formula absorbs quickly and can be used with your regular styling products.
Most hair products are either decades-old drugs with side effects (like minoxidil) or botanical blends without real clinical data. RE:YOU is neither. It is powered by NOVOGRO™, a proprietary set of molecules invented to tackle the root causes of hair thinning, and backed by a 190-participant clinical trial. 90-day results showed a 58% reduction in hair loss and breakage, with satisfaction nearly tripling over 90 days. If you are looking for results you can see and data you can trust, yes, it is worth it.
Yes, our product is designed for both men and women experiencing hair thinning or increased shedding. It supports healthier, fuller-looking hair regardless of gender and is suitable for all hair types.
Yes. RE:YOU is hormone-free, drug-free, and formulated without any ingredients known to be unsafe during pregnancy or breastfeeding. That said, we always recommend checking in with your OB/GYN before starting any new product during these life stages.
Yes. RE:YOU is effective across hair types, textures, and tones. Our clinical trial included women with straight, wavy, curly, and coily hair, and results were consistent across all groups.

One 35 mL bottle lasts about 30 days when used as directed. Clinical results were measured at 90 days, so we recommend a three-bottle commitment to see the full effect.

If you do not see or feel a difference after 90 days of consistent use, we will refund your money. No shipping the products back. Please follow the instructions on our guarantee page to qualify. We just ask you to track your progress which should also help you stay consistent enough to see results!

Our serum activates your hair follicles, which leads to better hair from continuous use. After you get the results that you need, you don't need to constantly help your follicles anymore and can reduce usage to once a week or once every few days instead of daily. This can generally happen 6–12 months after starting the serum and only depends on when you get to results you love. We don’t have any shedding effects from reducing use, as our technology targets multiple pathways that don't have withdrawal effects.

What Our Users Are Saying

As Featured In

Clinical proof

One of the Most Rigorous Clinical Trials Ever Run in the Beauty Industry.

Most companies juice efficacy results with small sample sizes, self-reported surveys, and biased experiment design. We did the opposite. We invested $500,000 in a 190-participant clinical trial, testing RE:YOU head-to-head against minoxidil, the gold-standard hair treatment.

Many of my patients have become frustrated with traditional therapies, so it is exciting to see promising new approaches emerge. Of course, great science only matters if people can consistently use the product. RE:YOU’s lightweight, non-greasy formulas feel more like skincare serums, making them easy to apply and seamlessly incorporate into a daily routine.

What excites me about RE:YOU is its novel dual-pathway approach, using molecules developed specifically for hair thinning to support both activity within the follicle and the surrounding environment needed for healthy hair growth. It is thoughtfully formulated with pregnancy and breastfeeding in mind, making it an especially interesting option for women.

Yulin Z.

52 years old

“I started noticing my hair thinning around the crown and wasn’t sure anything would help at my age. A few months in with RE:YOU, my hair feels thicker and looks fuller than it has in years. Friends keep asking what I’ve been doing differently.”

Mike L.

“What I love most is how lightweight the serum feels. It absorbs quickly and doesn’t leave any residue. After a month of use, I started noticing new baby hairs around my hairline and my hair overall feels stronger and more resilient.”

Linda C.
