The Science

What Copper Peptides Actually Do

Copper peptides are short chains of amino acids bound to copper. In hair care they are studied for their role in supporting the scalp environment where follicles do their work — circulation, the skin barrier, and the conditions that let a growth phase run its course.

Most serums include them at trace levels. Ours is built around them: 10% GHK-Cu and 5% AHK-Cu, in a water-light base designed to be used daily rather than saved for special occasions.

10% GHK-Cu — 10% The most researched copper tripeptide. Studied for its role in supporting follicle activity and a healthy, hydrated scalp barrier.
5% AHK-Cu — 5% A complementary copper tripeptide layered in to support strand thickness, density and overall hair resilience.
H2O Lightweight water base Fast-absorbing and non-greasy, so the serum layers into any routine without residue or buildup.

Three Steps, Once A Day

How To Use

Under a minute in the morning or before bed — the routine only works if it is easy enough to keep.

1

Part your hair

Part dry or towel-dried hair to expose the scalp wherever you want results.

2

Apply 1–2 ml

Use the dropper to apply the serum directly along the part line, hairline and any thinning areas.

3

Massage and leave in

Work it in with your fingertips and leave it on — no rinsing. Style as normal once it absorbs.

Questions

Frequently Asked

Still deciding? These are the things people ask us most before their first bottle.

Shop The Serum
When will I see results?

Plan on daily use for 6–12 weeks before you judge it. Some people notice less shedding earlier than that, but visible density follows a full growth cycle. Consistency matters far more than quantity.

Will it make my hair greasy?

No. It is a lightweight, water-based serum that absorbs quickly and leaves no residue, so you can apply it in the morning and style as normal.

How much should I use, and how long does a bottle last?

1–2 ml on the scalp once a day. At that rate the 30ML bottle is roughly a one-month supply and the 60ML is about two.

Is it for men or women?

Both. The formula is not gendered — it is built for thinning, damaged or aging hair of any type or texture.

Can I use it with my other hair products?

Yes. Apply it to the scalp first, let it absorb, then layer your usual styling products on top.

Is this a substitute for medical treatment?

No. This is a cosmetic serum, not a drug, and it is not intended to diagnose, treat, cure or prevent any condition. If you are experiencing sudden, patchy or rapid hair loss, please speak with a doctor or dermatologist.

What if it does not work for me?

You are covered by our 30-day money-back guarantee. If you are not satisfied, we will refund you in full — no questions asked.
