    Meeting my expectations

    I have only been using the GHK-Cu hair & scalp serum for nearly one month. Thus far, I can see less hair fall on my brush, and in my shower. My hairdresser even commented on it that she is noticing a significant decrease while styling my hair. I have not noticed any new hair growth or change in thicknesses- which I wouldn’t expect in this short timeframe. I look forward to seeing more results as I continue to use it over the next few months.

    No residue

    Love that this only has two ingredients and that it leaves absolutely no residue. It makes it really easy to use it in the morning and save my minoxidil for night. The only downside is the spray bottle. It's a silly, innefficent way to apply this to your scalp.

    Hair serum

    It looks like I had som hair growth. I went through the bottle way faster than it was supposed to last. I think the bottle should have been bigger, especially if its recommended to use morning and evening. I did not buy the samr product the second time around. I bought the GHK/AHK Cu. I feel this one really produced more hair growth. I am very pleased with that serum and will repurchase that one.

    Slow Progress, Good Results

    I have been using this for about 3 months and I am starting to see some growth. I am 46 and in perimenopause. I also started losing hair long before that after pandemic however many years ago that was. I am balding in my crown area of my head. I have used pretty much everything and honestly really expensive stuff to not even get any new hair growth. I saw my stylist a couple months ago, and she even mentioned that she is seeing new hair growth! She also mentioned that it looked much better in that area. I will admit that it’s very slow. I wouldn't expect fast results. You really need to be patient and check your scalp to see if you are going to continue to make the investment. I am going to continue to use this and see what happens. So far I am happy with this product. I will update this post with pictures next time.

Your Daily Ritual for Fuller-Looking Hair

Step 1

Apply to a Clean, Dry Scalp

Apply a few drops directly onto your scalp, focusing on areas that look thinner. Best used in the morning or before bed.

Step 2

Massage Gently for 30–60 Seconds

Use your fingertips to gently massage the serum into your scalp to support absorption.

Step 3

Let It Absorb & Stay Consistent

No need to rinse — the lightweight formula absorbs in minutes. Use daily; most people assess changes over 8 to 12 weeks.

The Science Behind GHK-Cu

Copper peptides, including GHK-Cu (Copper Tripeptide-1), have been studied in cosmetic and dermatology research for supporting the appearance of healthy skin and hair. They are used in topical products as cosmetic ingredients, not as drugs to treat hair-loss conditions.

GHK-Cu copper peptides have been studied in cosmetic research for their role in supporting a healthy-looking hair and scalp environment. Our formula is designed to work with your routine, helping hair look fuller and more resilient over time.

This is perfect for you if…

You're noticing thinning and want to support fuller-looking hair over time.

Your scalp feels dry or irritated and you want a more comfortable, conditioned scalp.

You prefer a clean, two-ingredient formula without fragrance or fillers.

This might not be for you if…

You expect visible changes in a week — give it 8 to 12 weeks of consistent use.

You're looking for a medical hair-loss treatment — this is a cosmetic product, not a drug.
