Real People. Real Results.

Your 12-Week Scalp Reset

Our AHK-CU + GHK-CU Hair Serum Pro delivers 4800mg of dual copper peptides in a simple twice-daily spray. AHK-Cu works at the cellular level to help hair-root cells resist premature die-off. GHK-Cu supports the broader follicle environment and scalp health. Two mechanisms, one formula.

Month 1

Month 2

Month 3+

Month 1

What's Happening:
Both peptides are absorbing into the scalp. AHK-Cu begins signaling to hair-root cells to stay active longer. GHK-Cu starts calming the scalp environment. Dryness and irritation may begin to ease.

What to Expect:
No visible changes yet — that's normal. This phase is about building the right conditions under the surface. Keep showing up twice a day.

✓ Formulated with Clinically Studied Ingredients

Carefully formulated with clinically studied ingredients and rigorously third-party tested for quality and consistency.

Month 2

What's Happening:
The follicle environment is shifting. Hair-root cells are getting more support from AHK-Cu. GHK-Cu is contributing to a calmer, more balanced scalp.

What to Expect:
Existing hair may start to feel stronger. Some people notice less hair in the shower drain or on their pillow. Fine "baby hairs" may begin to appear in thinning areas.

✓ Formulated with Clinically Studied Ingredients

Carefully formulated with clinically studied ingredients and rigorously third-party tested for quality and consistency.

Month 3+

What's Happening:
Consistency is paying off. Follicles supported by both peptides are producing hair in a healthier growth cycle. New growth has had time to come in thicker and more visible.

What to Expect:
Fuller-looking coverage in areas that were thinning. Hair that feels stronger overall. The difference between month one and month three is real, and it compounds from here.

Benefits Of Consistent Use

Follicle-Targeted Support

AHK-Cu works directly on hair follicles, helping hair-root cells resist early die-off. GHK-Cu supports the broader scalp environment. Together, they address hair thinning from two complementary angles.

Less Shedding, More Staying

Follicles that stay active longer shed less. With consistent use, many people notice fewer hairs in the drain and on the pillow within the first couple of months.

Calmer, Healthier Scalp

Dry, irritated scalps aren't great at growing hair. This dual-peptide formula helps create a more balanced scalp environment: less flaking, less tightness, better conditions for growth.

Works With What You Already Use

The water-based spray dries fast and layers under or over your existing products. No greasy residue, no reformulating your entire routine.

Three Ingredients. Nothing Else.

AHK-Cu, GHK-Cu, and distilled water. No sulfates, no parabens, no fragrance, no fillers. You can read the entire ingredient list in about three seconds.

Supports the Growth Cycle Where It Starts

Rather than masking thinning with volumizers, this formula works at the follicle level to support the anagen (growth) phase. It addresses the root cause, not the symptom.

Three Ingredients. One Job.

We stripped this formula down to what actually matters. No extras, no fillers, no 30-item ingredient lists that look impressive but don't do much.

Primary Active

AHK-Cu (Copper Peptide Complex)

AHK-Cu is a copper peptide tripeptide specifically studied for its interaction with hair follicle cells. In laboratory research, it helped hair-root cells (dermal papilla cells) survive longer than untreated controls. This is the lead peptide in the formula — chosen for its follicle-specific mechanism.

Supporting Active

GHK-Cu (Copper Peptides)

GHK-Cu is one of the best-researched copper peptides available, with evidence spanning scalp health, tissue remodeling, and growth factor signaling. It occurs naturally in the body but declines with age. Here it plays a supporting role — complementing AHK-Cu with broader scalp environment support.

    Its slowly working

    I’ve been using AHK-CU + GHK-CU Hair Serum Pro for a while now, and I’m genuinely impressed with the results so far. It’s definitely not an overnight miracle product — the progress is slow and gradual — but that actually makes me trust it more. Over time, I’ve started noticing my hair feels a bit stronger, healthier, and there’s a subtle improvement in thickness.

    What I appreciate most is that it doesn’t feel harsh or irritating on my scalp, and it fits easily into my routine. If you’re patient and consistent, it seems to do exactly what it promises. I’m excited to keep using it and see how the results continue to build.

    Copper peptide hair serum delivers quality and on it's promises

    I stumbled upon the use of copper peptides and had exhausted using a multitude of other pre-made oils and mixtures to no avail on my hair/scalp. I looked into many other companies and what copper peptides they offered and while there are much cheaper options on the market from other companies, when you account for the cost of the copper peptides at the alleged concentrations they are marketed, it begins to make you suspicious of the quality and whether you are getting you're buying. Neurogan offers lab-tested results affirming the purity and is GMP certified providing assurance you are buying the copper peptides in the highest quality.

    I am nearing the end of month two of using the product. I've opted to use it twice a day and I am a bit liberal with the # of sprays/areas i use it, so I'm on my 2nd bottle, but with more conservative sprays you can easily get more than a month even using it twice a day, and using it once a day extends that even further. While I'm only on the second month, so too soon to say how much an effect it has had on longer term growth, I have noticed a decrease in hair fall, my hair grows quicker, and my scalp feels healthier. All of these things have lead to it appearing thicker and I have finally started to see smaller hairs coming in, in the spots that previously were a bit more sparse including the widening of my hair part beginning to recover. I'm looking forward to what the end of the third and fourth month will look like at this rate. As an…

    It works

    I’m currently on my second bottle and I’ve noticed my hair seems thicker and I can't wait to see the results after a few more months.

    First bottle

    I use to struggle with scalp irritation and this serum has definitely improved my scalp health. It also feels like my hair is growing faster.

    AHK-CU + GHK-CU Hair Serum Pro

    I was very skeptical buying this spray, especially because it's pricey and didn't know if it would do anything. I've been suffering with male pattern baldness for the past 4-5 years and have tried everything from minoxidil, Finasteride, microderm rolling, stem cell injections and FUE. Nothing has worked at all. I started a regimen of 5mg of oral GHK-CU 2 x daily and AHK-CU + GHK-CU Hair Serum Pro topically 2 x daily. Within 1 month I could actually see a difference in actual hair growth and less breakage. It's only been 2 months since I've started this and I have stopped using the Minoxidil foam and only use the AHK-CU + GHK-CU Hair Serum Pro.

Morning. Night. That's the Routine.

Step 1

Spray Onto a Clean Scalp

Start with a clean, towel-dried (or fully dry) scalp. Pull your hair back and apply one spray to each side of the thinning area and one spray to the back — or 3 to 5 sprays across the scalp for broader coverage.

Step 2

Massage In for 30 to 60 Seconds

Use your fingertips to work the serum into the scalp. This helps with absorption and gets blood flowing to the follicles.

Step 3

Let It Dry, Then Layer

The formula dries in a couple of minutes. Once dry, apply other products as usual — styling products, oils, whatever your routine includes.

The Research Behind

In a 2007 study on human dermal papilla cells, AHK-Cu helped these cells survive longer by reducing premature cell death (apoptosis). Dermal papilla cells that die off early can shrink follicles and shorten the growth phase — contributing to thinning over time.

  • AHK-Cu — a newer, more specialized molecule with early research pointing to a targeted role at the hair follicle level, helping hair-root cells resist premature die-off.
  • GHK-Cu — a well-researched peptide with a broader evidence base covering scalp health, tissue remodeling, and growth factor signaling.

In laboratory conditions, AHK-Cu helped dermal papilla cells resist apoptosis — the programmed cell death that causes follicles to miniaturize. Hair-root cells treated with AHK-Cu stayed alive longer than untreated controls. [1]

This is perfect for you if…

You're noticing thinning around the crown or hairline and want to act early.

Your scalp feels dry or irritated and you suspect it's affecting your hair.

You want a non-hormonal, peptide-based alternative to Minoxidil or Finasteride.

You prefer a clean, no-filler formula backed by real research.

This might not be for you if…

You're expecting results in a week. This takes 9 to 12 weeks of consistent use.

You have complete baldness in the area — this works best where follicles are still active.

Is it legal to take AHK-Cu Peptides??

Yes, both AHK-Cu peptides are legal to take and safe to use in topical serum formulations like this one.

Are there any side effects?

No known side effects when used as directed. Avoid overuse or applying to broken skin.

Has anyone tried combining GHK-Cu and AHK-Cu?

Combining both is extremely rare, this is the first known product (from Neurogan Health) to deliver them together in a 1:1 topical spray.

How much am I getting per spray?

Each spray delivers an estimated dose with a 1:1 ratio of GHK-Cu to AHK-Cu, though exact mg per spray may vary slightly due to the spray cap.

What is AHK-Cu used for?

AHK-Cu is a synthetic copper peptide used primarily in hair and scalp formulations. It is designed to interact locally at the hair follicle level and has been studied for its role in follicle signaling and dermal papilla cell activity, which are involved in the hair growth cycle.

How long does AHK-Cu take to work?

Based on our testing and feedback from people in our network, results vary, but most users begin evaluating changes within 4–8 weeks, with more noticeable differences often appearing after 2–3 months of consistent use. Here is what one customer said: “Within about one month, I could actually see a difference in real hair growth and less breakage. It has only been two months so far.”

How do you use AHK-Cu for hair growth?

Pull your hair back and apply one spray to each side of the thinning area and one spray to the back of the scalp, then massage it in before it drips. Use once in the morning and once at night, and allow 4–8 weeks of consistent use to begin evaluating changes, with results commonly assessed after 2–3 months.
