“My scalp used to feel tight and itchy a day or two after washing. The mint feels cool without burning, and after a couple weeks my scalp just felt calmer. The hair changes came later, but that alone made me keep using it.”

What people notice first
Less in the drain
“By the third bottle there was noticeably less hair in the drain, and my part wasn’t catching my eye every time I looked in the mirror.”
L
A calmer scalp
“My scalp used to feel tight and itchy a day after washing. The mint feels cool without burning, and after a couple weeks it just felt calmer.”
D
The part filling in
“Short little hairs sticking up along my part when the light hit them. They’re still fine, but they weren’t something I was noticing before.”

Built for scalps that have been thinning for years
Not a quick fix, and not another oil. Tap any point to see it.
- Goes on the scalp Not the lengths. Hair is already dead — the follicle sits in living skin, and that's the only place anything can work.
- Absorbs in about a minute One dropper at night, thirty seconds of massage. Sleep on it and style as normal — no rinsing, no residue.
- Every active named on the label Rosemary, green tea, vitamin E and Japanese mint. No proprietary blend — and we'll tell you which one has no human study behind it.
- Ninety days to judge it A hair cycle runs in months. Thirty days expires before you could possibly know — so ours runs the full cycle, and you keep the bottle.

Results You Can See in the Mirror
2/5
Definitely not an overnight product. I was close to giving up after the first bottle, but by the third month I was shedding much less and the top of my hair looked noticeably fuller. I just wish the bottle lasted a little longer.

5/5
I’m 63 and my biggest issue was the amount of hair coming out when I washed it. I didn’t see anything dramatic the first month, but by the third bottle there was noticeably less hair in the drain and my part wasn’t catching my eye every time I looked in the mirror.

My scalp used to feel tight and itchy a day or two after washing. The mint feels cool without burning, and after a couple weeks my scalp just felt calmer. The hair changes came later, but that alone made me keep using it.

3/5
The serum itself has been very good for my scalp and I’m seeing lots of short little hairs around my part now. Took longer than I expected to notice anything, but the improvement has been steady enough that I’m continuing with it.

5/5
The shedding was the first thing that changed for me. Then around month three I started noticing these short little hairs sticking up along my part when the light hit them. They’re still fine, but they definitely weren’t something I was noticing before.
K
5/5
I’ve had fine hair for years, so I wasn’t expecting to suddenly have thick hair again. What I’ve noticed is that the top doesn’t separate into those obvious little gaps as easily anymore. It looks more filled in when I style it.
P
5/5
My hair always looked decent from the front and terrible from above. Bathroom lighting was brutal. After about 12 weeks the crown doesn’t look as see-through to me, especially when I wear my hair down.
S
5/5
I was worried this would leave my roots oily because it has castor and coconut oil in it. Surprisingly, when I use the right amount and massage it into the scalp, my hair doesn’t look greasy the next morning. It actually feels softer around the roots.

5/5
I’m almost 70, so I bought this with pretty low expectations. I still have thin hair, but I’m shedding less and the little wispy hairs around my part seem longer and more noticeable now. That feels like progress to me.
N
5/5
I’ve tried plain rosemary oil before and hated how heavy it was. This feels much easier to use. I like the cooling mint feeling, it doesn’t make my scalp feel coated, and my scalp flakes are nowhere near as noticeable as they used to be.
C
5/5
I didn’t take a perfect before photo, which I regret, but my hairdresser was the one who said she was seeing a lot of short new hairs through the top. I hadn’t mentioned the serum to her, so that got my attention.
D
5/5
I get seasonal dryness and little flakes around my part. Using this at night has made that area feel much less dry, and my scalp doesn’t feel stripped after wash day anymore. I’ve also noticed fewer hairs on my brush.

Fair questions
The things people actually ask us — answered plainly.
How long does one bottle last?
Thirty days. One full dropper covers the whole scalp, and a 50ml bottle holds thirty of those. A hair cycle runs about ninety days, so three bottles is the shortest period over which you can fairly judge it.
When will I actually see something?
Feel, within days. See, not for months. Scalp comfort usually shifts first, then shedding somewhere between weeks six and ten, then density last around month three or four.
Take a photo the day you start, under the same light, and another at week twelve. That's the only comparison that means anything.
Will it make my hair look greasy?
It's a serum, not an oil. One dropper spread across the whole scalp absorbs in a minute or two and leaves a satin finish rather than a slick one. Most people apply at night and style normally in the morning.
If your hair does look oily, you're using too much — the dose is one dropper for the entire scalp, not per section.
My scalp is oily already. Is this wrong for me?
Not necessarily. Oiliness and a stripped scalp barrier often travel together, and washing harder tends to make the scalp produce more, not less.
That said, if yours is genuinely very oily, start every other day and see how it sits before going nightly.
What if it doesn't work for me?
It won't work for everyone — no scalp serum does. If your scalp is smooth and shiny with no fine hairs on it at all, that follicle has closed and nothing topical reopens it. We'd rather tell you that than take the order.
If you've given it ninety days and you're not glad you did, email us. We refund you and you keep the bottle.
How fast is shipping, and can I return it?
Dispatched within one to two business days, tracked, and typically delivered in five to seven business days. Free over $50.
Returns run on the ninety-day guarantee — one email, no forms, no return portal, and nothing to post back.
