The 90-Day Path to Visibly Thicker Hair

Our GHK-Cu serum delivers a potent 2400mg dose of copper peptides directly to your hair follicles. At a cellular level, GHK-Cu has been shown to increase the production of growth factors and reduce inflammation, creating the optimal environment for hair to grow.

We use 6x more GHK-Cu than leading brands, which means you get faster, more visible results.

What’s Happening: Your scalp absorbs the GHK-Cu, reducing inflammation and preparing follicles for growth. You may notice up to 40% less shedding and a healthier scalp.

    GHK-CU Spray

    I ordered this to help manage inflammation on my scalp due to suspected folliculitis. So far, it helps reduce the itching. I will continue to purchase if it keeps working!

    So Far So Good

    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.

    No seeing results

    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?

Your Daily Ritual for Thicker Hair

Step 1

Apply to Clean, Dry Scalp

Use 3-5 sprays (3 for targeted areas, 5 for broader coverage) directly onto your thinning areas. Best applied 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 increase blood flow and absorption.

Step 3

Let It Absorb & Stay Consistent

No need to rinse. The lightweight formula absorbs in minutes. Use daily for best results. Most customers see visible changes in 8-12 weeks.

The Science Behind GHK-Cu

Copper peptides are one of the most well-researched ingredients for skin and hair rejuvenation. In a double-blind, placebo-controlled study of 100 participants with androgenetic alopecia:

  • 98% of participants using our 2400mg GHK-Cu serum reported visibly thicker hair.
  • Participants saw an average 40% reduction in hair shedding.
  • No significant side effects were reported.

GHK-Cu has been shown to stimulate the production of several key growth factors that are essential for hair growth.

This is perfect for you if…

You’re in your 30s, 40s, or 50s and noticing gradual thinning.

You want a science-backed, non-hormonal alternative to Minoxidil or Finasteride.

You have hair loss related to PCOS, Hashimoto’s, or stress.

You want to be proactive and prevent further hair loss.

This might not be for you if…

You’re looking for an overnight miracle. This takes 8-12 weeks of consistent use.

You have complete baldness. This works best on thinning areas with active follicles.
