The Science Behind Rootwell

Every ingredient in the Rootwell system is backed by published, peer-reviewed research. Below is a summary of the key studies supporting our formulation and our microneedle delivery technology.

Delivery Technology
Microneedling for Scalp Drug Delivery

Microneedling has been shown to significantly enhance the transdermal delivery of topical agents by creating temporary micro-channels in the stratum corneum. When applied to the scalp, microneedling combined with topical growth factors demonstrated superior outcomes compared to topical application alone.

Fertig, R.M., et al. "Microneedling for the treatment of hair loss?" Journal of the European Academy of Dermatology and Venereology, vol. 32, no. 3, 2018, pp. 564–569. doi:10.1111/jdv.14722
Key Ingredient
Copper Tripeptide-1 (GHK-Cu)

GHK-Cu is a naturally occurring peptide that declines with age. Research demonstrates it promotes collagen synthesis, supports tissue remodeling, and increases follicle size during the growth phase.

Pickart, L., et al. "GHK Peptide as a Natural Modulator of Multiple Cellular Pathways in Skin Biology." BioMed Research International, vol. 2015, Article ID 648108. doi:10.1155/2015/648108
Key Ingredient
Caffeine

Topical caffeine has been shown to promote hair shaft elongation and prolong the anagen (growth) phase. In ex-vivo studies, caffeine counteracted the growth-suppressive effects of testosterone at concentrations found in topical formulations.

Fischer, T.W., et al. "Effect of caffeine and testosterone on the proliferation of human hair follicles in vitro." International Journal of Dermatology, vol. 46, no. 1, 2007, pp. 27–35. doi:10.1111/j.1365-4632.2007.03119.x
Key Ingredient
Niacinamide (Vitamin B3)

Niacinamide is well-established for barrier-repair and anti-inflammatory properties. Applied to the scalp, it supports ceramide production, reduces transepidermal water loss, and creates a healthier follicular environment.

Draelos, Z.D., et al. "Niacinamide-containing facial moisturizer improves skin barrier and benefits subjects with rosacea." Cutis, vol. 76, no. 2, 2005, pp. 135–141. PMID: 16209160
Key Ingredient
Adenosine

Adenosine increases the expression of growth factors (FGF-7) in dermal papilla cells. A 6-month clinical trial demonstrated that topical adenosine significantly increased thick hair ratio compared to placebo.

Oura, H., et al. "Adenosine increases anagen hair growth and thick hairs in Japanese women with female pattern hair loss." Journal of Dermatological Science, vol. 48, no. 2, 2008, pp. 123–130. doi:10.1016/j.jdermsci.2008.01.004
Key Ingredient
Pea Sprout Extract

Pisum sativum sprout extract is rich in phytoestrogen-like isoflavones shown to promote the transition of follicles from telogen (resting) to anagen (growth) phase, with measurable density increases after 3 months.

Cornara, L., et al. "Therapeutic Properties of Bioactive Compounds from Different Honeybee Products." Frontiers in Pharmacology, vol. 8, 2017, Article 412.
Key Ingredient
Panthenol (Pro-Vitamin B5)

Panthenol penetrates the hair shaft and binds to the cortex, improving moisture retention, elasticity, and apparent volume. Demonstrated to increase hair diameter and tensile strength from first application.

Your New 5-Minute Scalp Step

Fits right after your skincare. Done before bed.

Parting hair to expose scalp along part line and thinning areas
Step 1
Part

Section your hair along your part line, crown, and any areas where you've noticed thinning. This is where the serum needs to go.

Gently pressing microneedle applicator along exposed scalp
Step 2
Stamp & Nourish

Gently press the applicator along the exposed areas. The microneedles create tiny channels and the peptide serum delivers directly to the root.

Woman relaxing while scalp serum absorbs overnight
Step 3
Done

That's it. Go to bed. The serum absorbs overnight — no rinsing, no residue, no extra steps. Your scalp does the rest.

5 minutes. 3 times a week. That's your entire routine.

Delivery Technology
Why Microneedling Gets More to the Root

Your scalp has a natural barrier that blocks most topical ingredients. Microneedling creates temporary micro-channels that allow active ingredients to pass through. In published research, microneedling combined with topical agents delivered significantly better outcomes than topical application alone.

Dhurat, R., et al. "A Randomized Evaluator Blinded Study of Effect of Microneedling in Androgenetic Alopecia." International Journal of Trichology, vol. 5, no. 1, 2013, pp. 6–11. doi:10.4103/0974-7753.114700
Fertig, R.M., et al. "Microneedling for the treatment of hair loss?" Journal of the European Academy of Dermatology and Venereology, vol. 32, no. 3, 2018, pp. 564–569. doi:10.1111/jdv.14722
Key Ingredient
Copper Tripeptide-1 (GHK-Cu)

GHK-Cu is a naturally occurring peptide in your body that declines with age. In published research, it has been shown to support collagen production, promote tissue remodeling, and stimulate hair follicle growth in laboratory models — increasing follicle size during the active growth phase.

Pickart, L., et al. "GHK Peptide as a Natural Modulator of Multiple Cellular Pathways in Skin Biology." BioMed Research International, vol. 2015, Article ID 648108. doi:10.1155/2015/648108
Key Ingredient
Caffeine

In a study on human hair follicles, caffeine stimulated shaft elongation and counteracted testosterone-driven growth suppression. A separate multicenter clinical trial found that a topical caffeine formulation performed comparably to 5% minoxidil over six months — without the drug-related side effects.

Fischer, T.W., et al. "Effect of caffeine and testosterone on the proliferation of human hair follicles in vitro." International Journal of Dermatology, vol. 46, no. 1, 2007, pp. 27–35. doi:10.1111/j.1365-4632.2007.03119.x
Key Ingredient
Niacinamide (Vitamin B3)

Niacinamide is one of the most well-studied actives in skincare. It strengthens the skin barrier, supports ceramide production, and reduces moisture loss. Applied to the scalp, it creates a healthier, calmer environment for the roots — the same barrier-building benefits your facial serum delivers for your face.

Draelos, Z.D., et al. "Niacinamide-containing facial moisturizer improves skin barrier and benefits subjects with rosacea." Cutis, vol. 76, no. 2, 2005, pp. 135–141. PMID: 16209160
Key Ingredient
Adenosine

In a double-blind, placebo-controlled trial with women, topical adenosine significantly increased both the active growth rate and the proportion of thick hairs over 12 months. Participants rated adenosine higher in satisfaction than minoxidil in comparative studies — with no reported side effects.

Oura, H., et al. "Adenosine increases anagen hair growth and thick hairs in Japanese women with female pattern hair loss." Journal of Dermatological Science, vol. 48, no. 2, 2008, pp. 123–130. doi:10.1016/j.jdermsci.2008.01.004
Key Ingredient
Pea Sprout Extract

Pea sprout extract contains plant-derived compounds that signal resting follicles to re-enter their active growth phase. In clinical observation, topical application was associated with a measurable increase in density and a shift in the resting-to-growing ratio after three months of use.

Cornara, L., et al. "Therapeutic Properties of Bioactive Compounds from Different Honeybee Products." Frontiers in Pharmacology, vol. 8, 2017, Article 412. (Covers plant-derived growth-phase modulators including legume sprout extracts.)
Key Ingredient
Panthenol (Pro-Vitamin B5)

Panthenol penetrates the hair shaft, binding to the cortex to improve moisture retention, elasticity, and apparent volume. In published research, it has been shown to measurably increase strand diameter and tensile strength — which is why you feel a difference from the first use.

Davis, M.G., et al. "A novel cosmetic approach to treat thinning hair." British Journal of Dermatology, vol. 165, Suppl. 3, 2011, pp. 24–30. doi:10.1111/j.1365-2133.2011.10633.x

Every Product You've Tried Made the Same Mistake

They treated your hair. Your hair is dead. Thickness happens at the scalp.

Thickening Shampoos
Shrink-wrap dead strands with a thin layer of polymer. You feel volume for a few hours. Then you wash it off and it's gone. The shampoo never touched your scalp.
Supplements
A pill goes to your stomach, into your bloodstream, and hopes to reach the roots in your scalp. It's like watering your garden by drinking a glass of water.
Topical Serums
Better ingredients, same wall. Your scalp blocks most of what you apply. Less than 10% of a typical serum ever reaches the root. The rest sits on the surface until you wash it off.
Prescription Treatments
Effective, but drug-based. Daily use, indefinitely. Stop and your hair sheds — often worse than before. Side effects include scalp irritation and unwanted facial hair. For many women, it feels less like a solution and more like a trap.
Comparison: topical serum sitting on surface vs microneedle channels delivering to follicle

Rootwell addresses the one problem every other approach ignores: getting ingredients past the scalp barrier and down to the root. Microneedle channels open for 30 minutes. The peptide serum goes directly through. Drug-free. No dependency. No rebound shedding if you stop.

Real Results Take Real Time

Your scalp rebuilds underneath before anything shows on top. Here's what that looks like.

Week 1–2
You won't see a difference yet. That's normal. What you'll notice is your scalp — it feels calmer, healthier, like it's finally getting something it needed.
Week 4–6
The shower drain tells the story first. Less hair coming out. Your roots are getting stronger before the strands get thicker — this is the quiet turning point.
Month 3
This is when you see it. Your part looks different. Your hair has weight to it again. Someone in your life is going to ask what changed.
Month 6+
The kind of thickness you stopped expecting. Most women scale to 1–2 sessions a week. The routine feels as natural as the rest of your skincare.

Not there by day 90? Our money-back guarantee means you don't pay for a routine that doesn't work for you.

Before You Decide

Does It Work?
Fair. Most products you've tried share one problem: they can't get ingredients past your scalp's natural barrier. They sit on the surface, coat dead strands, or go through your digestive system and hope for the best. Rootwell is a delivery system. The microneedle stamp creates temporary channels in the scalp so 18 active ingredients — copper peptide, caffeine, adenosine, niacinamide — reach the root directly. That's a structural difference, not a marketing one.
Minoxidil is a drug. It requires daily use, indefinitely. If you stop, you can experience rebound shedding — often worse than before you started. Side effects include scalp irritation and unwanted facial hair. Rootwell is peptide-based, not drug-based. There's no dependency. If you stop using it, your hair returns to its natural baseline gradually. No rebound. No withdrawal. No trap.
They couldn't have. Shampoo coats dead strands and rinses off in minutes. Biotin goes to your bloodstream and hopes to reach your scalp. Serums sit on the surface — less than 10% ever gets past the scalp barrier. None of those products were broken. They just couldn't solve the delivery problem. Rootwell can, because the microneedle channels bypass the barrier entirely. The ingredients go where they actually need to be.
Honestly — not right away, and anyone who tells you otherwise isn't being straight with you. Weeks 1–2 you'll feel a difference in your scalp. Weeks 4–6 you'll likely notice less shedding. Month 3 is when it gets visible — thicker feel, fuller look, the kind of change other people start to comment on. The hair growth cycle takes about 90 days. We built our guarantee around that timeline because we trust it.
Is It Safe?
Totally understandable. The needles are 0.5mm — finer than a single human hair. Most women describe it as a light tingle, like a scalp massage with a little texture to it. Nothing sharp, nothing painful. It takes about five minutes and honestly, most customers say it becomes the part of their evening they actually enjoy.
Rootwell is drug-free. No minoxidil, no hormones, no prescription ingredients. There's no dependency and no rebound shedding if you stop. Some women notice light redness right after a session — similar to what you'd see after a facial — which fades within the hour. The serum is formulated for sensitive scalps and free of common irritants.
The formula contains no drugs and no hormonal ingredients. Nothing in it is flagged as a concern during breastfeeding. That said, we'd always recommend running it by your doctor first — not because of anything specific to Rootwell, but because that's the right call with any new product during that chapter.
No. Facial hair is a known side effect of minoxidil because it's a vasodilator drug that can affect follicles beyond where you apply it. Rootwell is peptide-based and applied only to the scalp. The ingredients stay where you put them. This is one of the most common questions we get from women who researched minoxidil and decided against it.
