- Instant Root Refresh, Zero White Residue: Lifts excess oil at the roots, neutralizes odor, and leaves hair looking clean, full, and shiny in minutes — with a fresh lavender scent.
- What It Is (Honest Version): A liquid formula in a pump applicator — not an aerosol powder spray. The carrier is deodorized alcohol: it grabs oil, then evaporates in minutes, leaving a weightless, natural finish with no powder cloud and no white cast. If you're used to chalky aerosol dry shampoos, the feel is different by design.
- Keep Your Routine Gentle: Refreshing your roots between wash days lets you keep a consistent, gentle hair-care rhythm — no daily stripping, no compromise on freshness.
- Clean by Design: Free of silicone, paraben, sulfate and dye. Suitable for all hair types, including color-treated hair.
- How to Use: Shake well (about seven times). Pump a small amount onto the roots section by section (or into your palm), massage in with fingertips, then comb through or fluff for added volume. Dries down in minutes. 40+ uses per bottle.
- Size & Freshness: 100 mL / 3.4 fl oz. Ships in its original retail box. Best by 08/2027.

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.
