What to expect
Results vary.
Copper Crown is a copper peptide scalp serum formulated at a true 3% AHK-Cu, the copper tripeptide studied for the hair follicle rather than the face. It is boosted with 1.5% caffeine, fully disclosed on the label, and made for people who want to know exactly what they are putting on their scalp.
Most products sold as hair serums are skincare formulas in new packaging, often built around a skin-focused copper peptide complex at a fraction of a percent. This one is built the other way around: follicle-first, at a concentration printed on the bottle.
Free shipping from Texas, discreet packaging, and a 60-day money-back guarantee. Naturally blue from the copper peptide itself, with no added dye.

Transparency

Generic formulas vary. Compare each product's label before purchasing.
How to use it

Apply about 1 mL directly to the scalp where thinning is visible.
Gently massage the serum into the targeted area.
Leave it on overnight. No rinse is needed.
For first-time use, a patch test is recommended. Each 30 mL bottle provides approximately 30 days of nightly use.
Nightly routine
Hair changes slowly. Make Copper Crown part of your nightly routine and take progress photos under similar lighting so you can judge changes consistently over time. Individual experiences vary. Copper Crown is a cosmetic scalp serum.
Customer proof
“Excellent product. Hair looks thicker and feels thicker.”
Andrei G.
“I've used Copper Crown for about 2 months now. I'm mid 40's and have struggled with my hair getting thinner. It runs in my family and am trying to avoid going bald. I've definitely been seeing changes in my hair. I have hairs starting to grow back, and what I have left looks a lot better than before I started. I just started another bottle and like what I see so far.”
Jessie H.
“I've been using the hair serum for around 2 months now. I've got pretty thin hair, but since I'm getting older it has thinned a lot more. My hair is definitely getting thicker and looks much better. I'm gonna keep using to see how thick my hair gets. So far it's made a big difference.”

Rethink the routine
Shampoo and conditioner rinse away in minutes.
A face serum is not automatically a scalp formula.
If the label does not show the percentage, you do not know how much is inside.
Copper Crown was built differently. Hair first. Scalp first. Exact percentages disclosed.
