GHK-Cu Copper Peptide Hair & Scalp Serum
GHK-Cu Copper Peptide Hair & Scalp Serum
A minimalist daily scalp serum of just two ingredients — distilled water and the GHK-Cu copper peptide — made to support the scalp for fuller-looking hair.
Couldn't load pickup availability
Neurogan keeps this scalp serum to two ingredients: medical-grade distilled water and GHK-Cu, the copper tripeptide studied for its role in skin and scalp health. There are no carriers or fragrance to dilute it — just a light blue fluid you massage into the scalp once a day.
Worked into a clean scalp each morning or evening, it absorbs quickly and leaves no residue under styling. It is made in the USA by a family-run company, and is designed to sit at the base of a scalp-first routine rather than replace the rest of it.

I have been using this about 3 weeks so it's still a little early to tell, but I do think my shedding has reduced slightly and I see some baby hairs around my hairline coming in. I think I will need to use for probably another month or two to really see results, but I plan on ordering another bottle because I like what I've seen so far.
It works great and has great effects
I’ve been using the scalp serum for a month and I like how easy it is to use and clean up.
This really helped my hair, I have lots of baby hairs after continuously using. I’m so glad to have found this product :)
Finally a product that has decreased my hairloss,! Starting to see some thickness, and definitely seeing healthier hair, and some new growth!
Very good product
I just finished with my first bottle and there’s no results whatsoever. I’m scared to try a second one because there is no money guarantee in this product is expensive. So I’m torn.
I have white hair which the copper turns blue. Cannot use on hair. Are there any other uses for this product?
Great product! Awesome company! Delivering high quality supplements! On my 5th bottle and my hairs are growing back! Thanks for such a great product!
Came with green spot inside the bottle
This is a great product. The 4% GHK-Cu is double that of other brands and the spray means I can use it for my scalp to prevent hair loss. Highly recommended.
Love it!
This serum has helped the hair at my temples fill back in. This is part of my daily regime.
not happy
This product is fantastic! It’s easy to use, stays put without running everywhere, isn’t sticky, and won't discolor. After just 30 days of using it once a day, my hair and scalp already look and feel healthier.
I've been using the GHK-CU copper peptide hair serum for about 4 weeks and it's stopped my hair from shedding. I highly recommend this product, it really delivers! You will not be disappointed,
Im so excited to see my hair loss reversing!!!
So far so good scalp feels less dry and flakey will order more !
So far I haven’t really noticed a difference with any new hair growth but I’m only starting my second bottle. I will continue to be consistent and hopeful that results will start soon!
Great product
I have used this product for over 4 weeks now and it seemed to have stopped my hair loss. I have noticed my hair to be thicker than before. Lets see if it able to make some hair come back.
This product truly work less than 30 days utilizing and I have seen results. I can only imagine what my results will look like after 90 Days.
I received a defective bottle that wouldn’t spray, so Angeline answered promptly and solved my situation!! Thank you Angeline!!
This Copper Peptide serum is a much better value because of the volume of the actual product. Other competitor serums have ingredients that haven't been clinically proven to increase the effectiveness of the Copper Peptide. The fact that this serum contains only Copper Peptide and water shows a minimalistic approach, which will demonstrate the effectiveness of the serum without the fillers. I would recommend this for anyone trying a Copper Peptide product for the first time, or those wanting to switch to a product where the only ingredients are Copper Peptide and water!
About a month ago, my son told me about this product and he advised me to get it. I reluctantly ordered it and did not really have any expectations at all. To my surprise, after a week I could see that the texture of my hair was much different and actually healthy. I also noticed new “baby” hairs growing at the top of my head. My wife also ordered it because she was having hair loss due to menopause. She has also noticed that her hair was growing back and that it was also much healthier! I highly recommend this product !
Sprayer doesnt work
CSR said she would send new bottke and sprayer
Never received
Receivrd bottle with sprayer, product turns my silver growth blue!
In the year that I’ve been using this product I have noticed my hair is healthier and when you initially put it in, it definitely looks fuller. It’s great to pair with derma rolling. I find that doing that once a week and really getting it in after derma rolling makes the most difference overall really good company and really good product.
I'm only on my 4th week but this formula does give me high hopes.
Just in the first week alone i noticed less shedding when I brush my hair and in the shower.
Remarkable results and insane value! I remember buying copper topical peptides 5+ years ago in little vials that were so expensive with less results! Im sharing this topical spray with everyone! Rapid healing, hyperpigmentation and hair growth in one bottle of pure blue magic! So grateful i found this company and product! Thank you!
Only been on it a month for hair regrowth due to Telogen Effluvium and I can already see new growth. I also spray it on my face and neck after micro- needling. I love this stuff.
I received the serum in a timely fashion. I am currently using the serum, which is easy to use, however it is too soon to see any results. I appreciate not having to try to make the serum myself. I believe it is actually less expensive to purchase from Neurogen in lieu of buying all of the supplies and products to make my own. I feel the web site is easy to use. I am currently pinning while using this product twice a week. I will update in several weeks with results!
Absorbs fast. Gotta spray farther away so it doesn’t run quickly. But the only real issue is the blue stains skin sometime Which isn’t a issue if u rub it in after
