Thinning at the parting? 7 reasons this one-minute scalp serum is different from what you've tried
Shampoos rinse away. Oils sit on top. Here's why a leave-on serum is the step that stays where it's needed.

If your parting looks wider than it used to, or there's more hair in the brush, you've probably already tried something. A thickening shampoo. Rosemary oil. A tub of hair gummies. Here's why a leave-on scalp serum is a different kind of step, and why it's worth giving it months, not weeks.
It stays on your scalp all day
A shampoo gets about a minute before it's washed off. This is a leave-on serum: the drops go straight onto your parting and stay there. Nothing to rinse, nothing to wait for.
Four named complexes, strengths on show
No mystery blend. Every complex is listed with its strength, rounded out with biotin, rosemary leaf extract, violet rice extract and betaine, in a pH-balanced, water-thin base.
Water-thin, and nothing to wash out
Oils sit on top of your hair and have to come out again, usually with a double shampoo. This is water-thin: it absorbs in seconds and leaves no residue. And the new formula was made to work on every hair colour, so it won't change yours.
- Blonde
- Grey
- Red
- Brunette
- Black
The whole routine takes 60 seconds
Two or three drops on your parting, a few seconds of massage with your fingertips, and leave it in. Morning or night, whichever you'll actually stick to.
