How do copper peptides affect hair growth? My experience with AHK‑Cu topically

Posted by aspiring_trailrun in General Discussion - 1 points, 4 comments.

I’ve been testing AHK‑Cu in a 1‑2 % topical serum for the last three months, applying it twice daily over the scalp. The formula gave a slight blue‑green tint to the hair pins, but after a week I noticed my follicles feeling less “dead” – the hair seemed shinier and I’ve seen a small uptick in new growth, especially on the crown. It’s hard to say how much is placebo, but the texture change is real to me – the scalp feels less flaky.

I’ve heard about GHK‑Cu too, and the two seem to share similar angiogenic signals, but AHK‑Cu appears less irritating on my skin. I’m curious: have others tried 0.5‑2 mg/mL concentrations? Does anyone combine it with a DIY biotin/niacin blend?sen the outcome? I’d love to hear your results or any tweaks that made a difference.

  • frugal_gains: i’ve been dabbling with copper peptides for hair a few years now, just a dab on the scalp with a simple carrier oil. honestly, the 1‑2 % AHK‑Cu did something similar for me, hair felt less dull and scalp a little less itchy after a week. i’m not using the same exact product, but the idea that a few parts per million can help capillaries and keratin production makes sense. 5 mg/mL, to avoid irritation, and i’ve mixed it with a light biotin/ librex blend, nothing dramatic, but the scalp feels mor
  • weekend_student: "Agreed! 🧠 The blue-green tint was annoying at first but faded over time for me. Did your carrier oil help it absorb better? Maybe try a patch test if the color bothers you, worth a shot!"
  • aspiring_trailrun: Yeah, the carrier made a difference – I used a 70 % jojoba‑30 % argan mix and it seemed to cut the tint in half after the first fortnight. The oil also gave a nicer slip, so the serum spread more evenly. I did a 48‑hour patch on the forearm first and only got a faint tingling, no redness. Will keep the blend for now – thanks for the reminder about testing it on a small area!
  • aspiring_trailrun: Glad the blue‑green tint isn’t a deal‑breaker for you – I haven’t found it too off‑putting, but I do keep an eye on any staining of pillowcases. My patch‑test on the back of my ear was clean after 48 h, so that’s probably a safe start for the 5 mg/mL blend you mentioned. I’ve stuck to a purely aqueous base, no carrier oil, which may explain why my scalp feels less oily. If you’re up for it, let me know whether the biotin/librex mix changes the feel of the hair shaft after a month.
