Built for men who'd rather not add a step.
Most DHT formulas make you choose: a shampoo, then a separate conditioner, then a serum. This is one bottle. Shampoo and conditioner in a single 2-in-1 — so the routine actually survives a Tuesday morning.
What's in the bottle
Saw palmetto and Aminexil (the same family as Rx-strength DHT topicals), plus a peptide (Dipeptide-4), Biotin, Ceramides, and Rosemary. We list every ingredient in full, right here. You're an adult — you can read a panel.
Who it's for
Men noticing early thinning or a receding hairline, and anyone already following a dermatologist-directed routine who needs a wash that won't get in the way. Sulfate-free and silicone-free, so it lifts DHT-laden sebum without stripping the scalp or leaving residue that blocks your other treatments.
What to expect
Fuller-feeling hair from the first wash. Many men tell us they see less hair in the drain over a few weeks of consistent use. We're not promising regrowth — we're promising 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, rinse. Daily use is fine.

— The team behind RootStim
Who it's for
Who it's for
RootStim DHT Blocker Shampoo is built for men who've started noticing the early signs: more hair in the shower drain, on the pillow, 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 before it gets worse.
- The protocol-stacker (30s-40s) already following a dermatologist-directed routine, who needs a daily cleanser that's compatible — sulfate-free and silicone-free.
The honest promise: a cosmetic shampoo that helps reduce shedding and supports a fuller-looking, healthier scalp — not a regrowth drug.
Hair thinning is progressive — the follicles you keep are easier to support than the ones you've already lost. If you're noticing more shedding or scalp showing through now, that's the window to start a consistent, gentle routine.
Why it works
Why it works
A genuine multi-active stack in a single 2-in-1 bottle:
- Saw Palmetto and Aminexil — actives associated with hair-thinning support.
- Dipeptide-4 plus Biotin, Niacinamide, and Panthenol to support the look of thicker, healthier hair.
- Ceramides, Centella Asiatica, Aloe, and Piroctone Olamine to support a calmer, healthier scalp.
Truly sulfate-free and silicone-free, so it cleans gently and won't interfere with a topical routine. Honest timeline: the most consistent win men report is less shedding over weeks of regular 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.
