Description +

Pair Renata's Peptide Serum with a premium titanium derma roller for a simple two-step scalp routine. The roller's fine, beginner-friendly needles gently prep the scalp, helping the serum's peptide and botanical complex absorb more effectively, while supporting healthy circulation to the scalp surface.

How to use +

Start with a clean, dry or slightly damp scalp.

Gently roll the derma roller over the scalp in a few directions (vertical, horizontal, diagonal), using light pressure — no need to press hard enough to feel discomfort.

Apply a few drops of the Peptide Serum directly to the scalp.

Massage the serum in with your fingertips for 1-2 minutes to ensure even distribution.

Use daily, or as part of your regular scalp routine. Clean the roller with rubbing alcohol before and after each use.

Five-peptide complex (sh-Polypeptide-1, sh-Polypeptide-9, sh-Polypeptide-11, sh-Oligopeptide-2, sh-Oligopeptide-10) — supports the appearance of thicker, more voluminous-looking hair

Scutellaria Baicalensis & Saw Palmetto — support a balanced, nourished scalp environment

Eucalyptus & Rosemary extracts — soothing, refreshing feel on application

Lightweight, fast-absorbing formula — a few drops, once daily, no complicated regimen

Derma Roller Features

  • 0.25mm titanium needles — a beginner-friendly length designed for gentle scalp care, not deep needling
  • Enhances serum absorption — the fine needles create micro-channels that help the Peptide Serum penetrate more effectively than applying alone

After my second baby, I was losing hair in the shower every single day. I tried so many supplements and "natural" shampoos that didn't work. Three months into Renata's Peptide Serum and my part looks fuller and I'm not finding clumps in the drain anymore. I finally feel like myself again at 34.

Why Most Hair Treatments Fail

Why Most Hair Treatments Fail (And Why Renata Doesn't)

Most hair-growth products on the market are built around long ingredient lists and big promises, but many of the ingredients advertised as “active” against hair loss have little or no clinical evidence behind them. Some popular treatments can also cause scalp irritation, and certain hair products have been associated with reports of hair loss, breakage, and thinning.

That's why so many people try hair-growth products and see no results. They want thicker-looking hair, but keep getting the same thin-looking, flat results.

Renata is different. Our Peptide Hair Serum combines five bioactive peptides with botanical extracts, including arginine, rosemary, and saw palmetto, to support the appearance of thicker, fuller, healthier-looking hair.

The peptides, including sh-Polypeptide-1 and sh-Oligopeptide-10, help support the appearance of fuller hair, while soybean and wheat germ extracts contribute to a smoother, healthier-looking finish. Rosemary and eucalyptus extracts add a refreshing touch, and arginine helps support the appearance of hair strength and vitality.

And we didn't stop at the serum. Our bundle includes a premium titanium derma roller, giving you a complete scalp-care routine rather than just another bottle of serum.

Apply a few drops directly to your scalp, gently massage for 1–2 minutes, and use the roller as directed. A simple, consistent routine designed to support the appearance of thicker, fuller, healthier-looking hair.

After my second baby, I was losing so much hair I started counting strands in the shower drain every morning, which is a genuinely awful habit to get into. I started the Renewal System eight weeks postpartum, rolled before bed, serum every morning. By week six I just... stopped counting. Not because I forgot, but because there was nothing alarming to count anymore. My part looks fuller too."

I'm the person who's tried six different hair oils and three 'clinically-backed' serums with basically nothing to show for it. I gave this three months, actually used the roller twice a week like it says, and my hairline along my part is visibly less see-through in photos. Not overnight, not magic, but it's the first one that's actually done something.

I didn't even mention I'd started anything new. At my last cut, my stylist said my regrowth along my crown looked noticeably thicker than my last visit four months ago. I've been doing the serum every morning and the roller once a week since then. That's the first time anyone's noticed before I said anything.

I'll be honest, I've never stuck with a hair routine longer than three weeks. Something about having just two steps made it actually stick this time. My ponytail feels less flat than it did in the spring. I know that's not dramatic, but for someone who gave up on everything else, it's enough to keep going.

Frequently Asked Questions

Find answers to common questions about our products, shipping, returns, and more.

What does Renata Do? +

The Renewal System pairs a five-peptide serum (including Arginine, Scutellaria Baicalensis, and Saw Palmetto) with a premium titanium derma roller. The roller preps the scalp to help the serum absorb more effectively, supporting the appearance of thicker, fuller-looking hair with consistent daily use.

How is Renata different from other hair treatments? +

Most hair serums are a single product with a long ingredient list and no way to tell what's actually reaching the scalp. We built a two-step system instead — the roller improves how much of the formula the scalp can absorb, so you're not relying on the serum to do all the work sitting on the surface alone.

How long until I see results? +

Hair growth runs on its own biological timeline — most people need at least 90 days of consistent use before noticing a real difference, and meaningful change in thickness or shedding typically takes closer to 3-6 months. That's why most people buy the 3 or 5 month supply.

How do I take it? +

Roll gently over the scalp 1-2 times per week, then apply a few drops of the Peptide Serum daily and massage in for 1-2 minutes. Two simple steps, most of which take under two minutes.

What is your return policy? +

We offer a 30-day return policy. If you're not satisfied with your purchase, you can return it within 30 days for a full refund or exchange.
