    "Nine months postpartum and every blood test came back normal — so nobody had anything for me. Three weeks with this and my scalp finally feels calm, my roots look fuller, and I'm not dreading the shower drain. First thing that's helped."

    "I'm 27 and the prescription sat in my cart for months — I couldn't commit to something I'd be on forever. Two minutes a night with this instead. My scalp feels alive, my part looks fuller, and I finally feel like I'm doing something."

    "I bought it for the itch, not my hair. Greasy by day two, scratching my head in meetings — that's gone. The cooling is unreal. Then by week three my roots looked fuller too. Wasn't even what I came for."

FAQs

What does this serum actually do?

Two jobs in one pass. Microscopic spicules gently clear the buildup sitting on your scalp, and the brush puts vegan PDRN, cica and caffeine exactly where they're needed — on the scalp, not on your hair. A calmer scalp, and fuller-looking roots over time.

Will this work if nothing else has?

Most serums sit on your hair and never reach your scalp — which is why so many of them do nothing. Cica Root is built around getting in: the brush parts your hair, the spicules clear the way. We can't promise it'll work for everyone, but it's a different mechanism to whatever you've already tried.

How do I use it?

Part your hair into sections. Squeeze a pea-sized amount through the brush, directly onto your scalp — not onto your hair. Massage for a full minute. That minute matters more than anything else: it's how the spicules do their work. Leave it in, no rinsing.

How long until I see results?

You'll feel the cooling from the very first use. A calmer, less itchy, less oily scalp usually comes within 2–3 weeks. Fuller-looking roots take longer — hair moves slowly, and anyone promising you otherwise is selling you something. Give it 8–12 weeks of consistent use.

What does the tingling feel like?

Cool and minty, not burning. Most people describe it as the first product they could actually feel working. It settles within a couple of minutes. If it feels like more than a tingle, use less and go every other night.

Will it make my hair greasy?

No — it's water-based and lightweight, and it goes on your scalp rather than your strands. The one mistake people make is using too much. A pea-sized amount is genuinely all you need; more won't work faster, it'll just sit there.

Is it right for me?

If your scalp is itchy, oily or irritated, or your part has widened and your ponytail feels thinner, it's made for you. It's especially loved by women dealing with postpartum shedding. Skip it on broken or badly inflamed skin, and patch test if you react easily.
