Step 2, in big bottles — the shampoo + conditioner pair in 500 mL. The shampoo is the foundation; the conditioner is the optional second step. These are the same two steps in generous 500 mL (16.9 fl oz) bottles, so you reorder less often.
Two steps designed to work together, not two unrelated bottles: the sulfate-free shampoo cleanses and conditions the scalp, then the conditioner smooths and detangles so fine, fragile strands feel stronger and look fuller. Gentle enough for daily use on sensitive, color-treated hair.

Who it's for
Who it's for
For women 45–60 noticing more shedding, thinner density, or finer hair — through perimenopause, menopause, or postpartum changes — who want one complete, plant-forward daily routine in big bottles, instead of juggling unrelated products.
Why it works
Why it works
This is a 2-step botanical system, designed to work together:
- Step 1 — Growth Shampoo: plant actives (Rosemary, Biotin, Saw Palmetto, Caffeine) cleanse and refresh the scalp for a clean, conditioned foundation. Sulfate-free.
- Step 2 — Conditioner: strengthens and smooths so fragile, fine strands break less and look fuller.
Used consistently across a full 90-day routine, the two steps build on each other for a daily, gentle scalp environment and healthier-looking hair.
How to use
How to use
Step 1 — Shampoo: apply to wet hair, massage into the scalp 1-2 minutes, rinse. Step 2 — Conditioner: work through mid-lengths to ends, leave 1-2 minutes, rinse thoroughly. Hair typically feels thicker around week 6; by week 12, visibly fuller, thicker-looking hair is the goal. Individual results vary.

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.
