Many customers notice improvements from the very first weeks. But like any real hair growth routine, the transformation happens gradually as your scalp and hair follicles become healthier.

First 30 days:
Your scalp starts to rebalance and become healthier. Hair feels softer, stronger and more moisturized. Many customers already start noticing small baby hairs appearing around the edges, hairline, the beard area, especially if those areas were thinning.

Days 30–60:
This is where most people begin to see clearer progress. The new baby hairs start getting thicker, your hair looks fuller and healthier, and shedding often reduces. Your scalp feels more nourished and hydrated.

Days 60–90:
This is when the real difference becomes visible. Many customers notice stronger growth, longer hair, new baby hairs filling in thin areas, more shine, and a healthier scalp overall. Your hair simply looks and feels more alive.

Hair growth takes time, but consistency is everything. Using GHK-Cu Copper Peptide Hair Serum regularly helps nourish the scalp, support stronger follicles, and create the conditions your hair needs to grow naturally.

1 bottle typically lasts around 30–60 days.
2 bottles (our recommended amount for best results) usually last around 60–90 days with regular use.

Most people start seeing early improvements in the first month, with the most noticeable changes coming from staying consistent over time.

That’s why every order is covered by our 60-day Growth Guarantee. If you use it consistently and don’t see real progress, we’ll refund you.

Use once daily for best results. Below are three simple steps to apply our GHK-Cu copper peptide for stronger, shinier, healthier hair.

One: Spray onto the Scalp
Spray a few times directly onto a clean, dry scalp, focusing on your part and any thinning areas.

Two: Massage It In
Gently massage the serum into your scalp with your fingertips for 30 to 60 seconds as you spray so it stays on the skin instead of running down.

Three: Let It Absorb
No need to rinse. The water-light formula absorbs in minutes without leaving hair greasy, sticky, or weighed down. Style as usual.

Store GHK-Cu serum in a cool, dry place away from direct sunlight or prolonged exposure to heat. Keep tightly closed at room temperature.

Our GHK-Cu Copper Peptide Hair Serum is made in the USA, using a simple, water-based formula containing distilled water and GHK-Cu copper peptides.

Worth every single penny for postpartum shedding!

If you are dealing with postpartum hair loss, you know how incredibly stressful it is to see your hair coming out in clumps. I was desperate for something that actually worked, and after seeing the ingredients in Maxgrows GHK-Cu Copper Peptide Serum, I decided to give it a try. I’m not going to lie it is definitely an expensive product, and I hesitated at first because of the price. But after using it consistently, I can confidently say it is 100% worth the investment. I've noticed a significant reduction in shedding, and my scalp feels so much healthier. It's lightweight, doesn't leave my hair greasy, and actually delivers results. If you're on the fence because of the cost, take the plunge.

2 weeks and seeing results already!

I wanted to wait until I could see if I saw any results before reviewing and honestly did not expect to even make a review for 2-3 months. I started this product Aug 7th, and today is Aug 19th. I swear I can see change! I included a picture for those searching to decide. Top is day 1 and bottom is day 13. I spray morning before I go to work and night before bed I am not sparingly with it. I also rub it in. If you blow dry your hair after, you can fix your hair as normal! (Both pics are post shower when I notice the loss the most). I hope this helps someone searching for hope! I am 33 with Hashimotos and pcos. I’m also on glp1 for those. The hair loss has been so disheartening. I am excited to have my confidence back!

I'm so happy with the results.

I’m always skeptical of any type of hair restoration, I’ve done finasteride, minoxidil, but these copper peptides, combined with my red light therapy, has brought my hair back to life, I was doing the same protocol with minoxidil and finasteride, and it was too volatile, if I stopped using them for a week, it would reverse everything I did and made it worse, but these collagen peptides, works so good I finally can stop wearing a hat, this company definitely hit the spot very happy and can’t wait to see more results as it goes on thank you guys for bringing me back some happiness. :)

Best results of any peptide I’ve tried

I've gone through many peptide products and I'm sticking with this one. It goes further and has the best results of what I tried so far.

What you see is what you get

It looks exactly as it shows in the pictures. I have read over multiple products and this one shows to be truly the authentic article. I will update my review in two months as I have thinning hair and will update if this works or not. I do recommend taking a one a day vitamin while using this peptide to further assist hair growth and strengthening. I have long hair down to the middle of my back. I am very eager to see if this thickens and strengthens my hair. I will also be using Hims minoxidil as well.

Hope to see the result soon!

I ordered this serum for myself and am looking forward to seeing the results. It was well packaged, has no scent, and comes in a blue color. The texture is lightweight and liquid, and it sprays easily.

Seems to Help Delay Gray Hair

It’s been helping delay my gray hairs. According to research, this is one of the few compounds showing promising results for gray hair. As soon as I noticed the first couple of gray hairs, I started applying it as part of a mix, and no new gray hairs have appeared so far. Will continue using it.

Quality copper peptides

I think this product works well. I used it for about a month, mostly around my front hairline, and noticed more baby hairs filling in so I believe this is a genuine, high quality product. Unfortunately, I went back to light blonde and now I worry about the blue pigment staining my hair. The blue color is perfectly normal for copper peptides, but maybe doesn’t mix so well on bleached hair that will readily absorb any pigment. Considering trying this on my eyebrows next though!

Very Surprised at How Well this Works!!!

I was a little put off when I saw that the serum was blue. This, however, is the natural color of copper peptide. And that is all this little bottle contains -- distilled water and GHK-Cu (glycyl-histidyl-lysine-copper). I was hugely surprised within just a day that my hair was not only shinier and softer but also started feeling thicker. Is that possible? Apparently so, because within another few days I saw hair growth and again my hair felt thicker, fuller, and healthier. Directions are simple: just spray on scalp, especially areas with thin hair. Then use scalp massager or fingers (I used fingertips) to promote circulation. You should also let it dry before blow drying or curling/straightening hair. I really like how well this works AND that it is JUST copper peptide and water. No parabens, no dye, no fragrance! The serum is made in the USA (California) and is lab tested. I was really very skeptical of this but now I'm very much a fan. The price seems fair given that this really does work. Also, you just need a few sprays morning and evening -- again, directly on the scalp. If your hair is thinning or if you want to improve your scalp health or have softer, thicker feeling hair, this is really very good. Recommended!

My hair feels great!

it makes my hair feel great! I like that it's made in the USA and you can just spray it on. Both my husband and I have problem scalps - me, itchy and hair loss, him, flaky and dry. And we both love this formula! It has a money back guarantee, made in the USA so you have nothing to lose trying it !

Frequently Asked Questions

How long before I notice a difference?

Give it 8 to 12 weeks of daily use. The first weeks are about consistency, and some people notice their scalp feels more comfortable first. Results vary from person to person.   

Will it tint my hair blue?

The serum is blue because of the copper peptide. On most hair it absorbs without a trace. On very light, white or silver hair it can leave a temporary tint, so spray at the scalp rather than along the lengths and massage it in. Any tint washes out with shampoo.   

Once or twice a day? How long does a bottle last?

Use it once daily: a few sprays on a clean, dry scalp. At that rate one 2 oz (60 mL) bottle lasts about 60 days, depending on how much you spray each time. Subscribe and Save takes 20% off every bottle.   

Can I use it with minoxidil or other hair products?

It is a two-ingredient, water-based serum, so it fits easily into most routines. Spray it on first and let it absorb before any styling products. If you use minoxidil or any other prescription or medicated product, ask your clinician how to combine them. We do not claim that combining products gives better results. 

Can I use it after derma rolling or microneedling?

Microneedling breaks the skin barrier, so follow your professional's advice or the device instructions. Many people wait until the scalp has settled before applying any serum. 

Can I use it on color-treated hair?

Yes. It is a water-based serum applied to the scalp and suits all hair types. If your hair is bleached, very light or silver, try it on a small area first because of the blue color. 

Is this a hair-loss treatment?

No. It is a cosmetic product, not a drug. It may help condition the scalp and support the appearance of fuller-looking hair. For sudden or patchy hair loss, see a doctor or dermatologist. 

What if it does not work for me?

We offer a 60-day money-back guarantee. If you are not happy for any reason, let us know and we will give you a full refund.
