Fuller-looking, thicker-feeling hair — in one bottle, in the time it takes to shower.
Most thickening routines make you stack a shampoo, a conditioner, and a serum. This is one 10 oz bottle: a 2-in-1 that cleans and conditions in a single step — so the routine actually survives a Tuesday morning.
What's in the bottle
A genuine multi-active blend — Saw Palmetto, Aminexil, a peptide (Dipeptide-4), Biotin, Ceramides, and Rosemary — chosen to support the look of thicker, fuller hair and a healthier-feeling scalp. Every ingredient is listed in full, right here.
Who it's for
Men noticing finer, thinner-looking hair or a receding-looking hairline, and anyone already following a scalp routine who wants a daily wash that fits in. Sulfate-free and silicone-free, so it cleans gently without stripping the scalp or leaving residue.
What to expect
Used consistently over a few weeks, most men tell us their hair looks and feels thicker. We make no medical claims — just an honest, well-formulated wash that supports the hair you have.
How to use
Apply to wet hair, work into a lather, leave 1–2 minutes, then rinse. As a 2-in-1 it cleans and conditions in one step. Daily use is fine.

— The team behind RootStim
Who it's for
Who it's for
Built for men who've started noticing the early signs — finer, thinner-looking hair, or scalp showing through at the part or temples.
- The early-stage guy (mid-20s to mid-30s) who's just seeing thinning and wants to act early.
- The protocol-stacker (30s-40s) already following a scalp routine who needs a daily wash that's compatible — sulfate-free and silicone-free.
The honest promise: a cosmetic 2-in-1 that supports the look of thicker, fuller hair and a healthier-feeling scalp. It makes no medical claims.
Thinner-looking hair builds gradually — the sooner you start a consistent, gentle routine, the more there is to work with. If you're noticing finer hair or scalp showing through now, that's the moment to start supporting the look of fuller, thicker hair.
Why it works
Why it works
A genuine multi-active blend in a single 2-in-1 bottle:
- Saw Palmetto and Aminexil — well-studied hair-care actives.
- Dipeptide-4 with Biotin, Niacinamide, and Panthenol — chosen to support the look of thicker, fuller hair.
- Ceramides, Centella Asiatica, Aloe, and Piroctone Olamine — to support a calmer, healthier-feeling scalp.
Truly sulfate-free and silicone-free, so it cleans gently and won't leave residue. Honest timeline: most men tell us their hair looks and feels fuller over weeks of consistent use — steady support, not an overnight fix.
How to use
How to use
Use in place of your regular shampoo. Massage into wet hair and scalp, lather, and leave on for 2-3 minutes so the actives reach the scalp. Rinse thoroughly. As a 2-in-1 it cleans and conditions in one step. If you also use a scalp topical, shampoo and rinse first, then apply your topical to a clean scalp.

Common Questions
Is RootStim a hair loss treatment?
Is RootStim a hair loss treatment?
No. RootStim is cosmetic scalp care — not a drug treatment. It's a daily shampoo-and-conditioner routine that cleanses the scalp, conditions the hair, and supports the look of fuller, thicker-looking hair.
It isn't a medicine, and nothing on this site is medical advice. If your shedding is sudden, patchy, or comes with an irritated scalp, please see a doctor — that's a conversation for a professional, not a shampoo bottle.
When should I expect results?
When should I expect results?
Hair works on its own schedule, so here's our honest timeline.
Weeks 1–2: the routine settles in — your scalp feels cleaner and lighter, buildup rinses away, and hair feels softer to the touch.
Around week 6: hair typically feels thicker and easier to style, and many notice it starting to look fuller at the roots.
By week 12: visibly fuller, thicker-looking hair is the goal.
Individual results vary. This reflects what customers typically report over a consistent routine — not a promised outcome. We ask you to judge at 90 days on purpose: that's how the guarantee is built.
Does it contain minoxidil?
Does it contain minoxidil?
No. This is a cosmetic hair-and-scalp routine — no minoxidil, and no drug actives of any kind. Every active in the formula is named in full on the label and explained on our Science page. No secret blends.
