Why it belongs in your routine

Moisture-focused scalp care
Formulated with panthenol and sodium hyaluronate: humectants that attract and retain water. A little attention for the skin beneath your hair.
Two copper peptides, one step
GHK-Cu and AHK-Cu bring two distinct amino-acid sequences to the formula, alongside niacinamide, caffeine and our moisture-binding ingredients.
No extra wash
Part your hair, apply 4–6 drops to the scalp and gently massage. Leave it in. One small step, once a day.

Six featured ingredients, with names, concentrations and roles explained. Follow the science as far as your curiosity takes you.

What it does
A daily scalp-care formula combining two copper-binding peptides with niacinamide, caffeine, panthenol and sodium hyaluronate. Peptides are short chains of amino acids. Panthenol and sodium hyaluronate are used as humectants, ingredients that help attract and retain moisture.
This is cosmetic scalp care. Ingredient research is not a clinical result for the finished serum.
How to use it
Once daily, apply 4–6 drops directly to a dry or towel-dried scalp. Part your hair, apply to the skin, gently massage and leave in. Do not rinse. For external use. Follow the finished label and stop use if irritation occurs.

Iqra IftikharThis serum works wonders! Already pre-ordered the patches. So excited for them.
★★★★★
TanyaI know it’s ‘just hair,’ but seeing more scalp every time I did my hair really got to me. Having photos where I can see progress has meant more than I expected. It’s been gradual, but I’m happy I stuck with it.
★★★★★
TinaI’m a little more then 6 weeks in. I kept checking the mirror every day, which I do not recommend unless you enjoy driving yourself insane. I just I noticed all the little hairs. Already ordered another!
★★★★★
CathyMy issue with scalp products is that they make my hair look like it needs washing immediately. This one fits into my routine without that whole situation. I’m consistent with it because it’s easy.
★★★★★
ChristinaMy husband noticed before I did. He asked what I was doing differently with my hair. This is a man who didn’t notice when we changed the curtains. So yes, I am pleased.
★★★☆☆
DianeThe product is easy to use. My hair looks better but I’m still undecided about the value for money.
★★★★★
VanessaI actually enjoy the little scalp massage before bed. An unexpected bonus.
★★★☆☆
JamesStill working through the bottle. No strong opinion yet, especially at this price.
★★★★☆
AndreaMy wife bought it, but I’m the one who remembers to use it. So far so good.
★★★★★
NadiaI wanted to know what was in it before ordering, and the ingredient breakdown helped. Some of the science went over my head, honestly, but I appreciated being able to read it.
★★★★☆
SarahStill early days. Mostly pleased that I’ve actually been consistent with it. Usually I buy these things, use them three times and forget they exist.
★★★★★
LisaThe leave-in part sold me. I do not have the energy for anything that involves getting back in the shower.
★★★★☆
AndreaWasn’t thrilled about spending $79 on another product. I like it so far, but I’ll need longer before deciding whether I’d buy it again.
★★★★★
MichelleI keep it beside my toothbrush because otherwise I will absolutely forget. Easy enough to fit into my evening.
★★★★★
LisaThe texture has changed, I’m starting to see it.
★★★★★
Maria StellaSo far I love it. It leaves my scalp feeling fresh. And I 'm starting to see an improvement in the quality of the hair.

Research notes & sources
Niacinamide has been studied for barrier lipids and moisture loss in skin. This supports ingredient education, not a week-four result for the finished serum.
