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. 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.

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!

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.

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.

Hair health has always been important to me, but I’ve often felt frustrated by how many products promise results without addressing the root of the issue. That’s why RE:YOU feels so different to me. It’s become a part of my daily routine.

What stood out to me about RE:YOU is how seamlessly it fits into a real beauty routine. It feels like an extension of skincare, just for the scalp and hair follicles. I love how it supports the look of fuller, healthier-looking hair over time, while still feeling lightweight and easy to stay consistent with.

I’ve been using RE:YOU for a few months and love the results! I noticed my hair got thinner following each pregnancy but with RE:YOU I’m starting to see regrowth. I also love the way the serum feels when I apply it to my scalp.
