Skin and hair on GHK-Cu: a week-by-week timeline
GHK-Cu works by signalling repair, and repair takes time. Collagen turnover is measured in weeks and hair cycles in months, so the order in which things change is fairly predictable. Track it properly and you will see it.
Weeks 1–2: hydration and calm
The first thing most people notice is that skin holds water better and looks less irritated. Redness settles, tightness after cleansing fades.
This is the anti-inflammatory and matrix-support side of the peptide arriving before any structural change.
Weeks 3–6: texture and firmness
New collagen and elastin start to show up as smoother texture, softer fine lines around the eyes and mouth, and skin that feels thicker rather than papery.
Existing marks and healed blemishes tend to fade faster in this window because remodelling is accelerated.
Weeks 6–12: hair density
Follicle changes lag skin changes. From around week six you may see less shedding first, then finer regrowth at the hairline and crown, then increased overall density towards week twelve.
Hair is the slowest signal in the whole protocol — judge it at three months, not one.
Beyond 12 weeks
Structural gains keep accumulating as long as you stay consistent. Most people continue at 2.5 mg three times a week; some move to two doses a week as a maintenance rhythm once they are happy.
How to actually track it
- —Photograph the same three angles in the same light on day 0, then every two weeks.
- —Hairline and crown photos with hair dry and parted the same way.
- —Judge skin by feel as well as look — thickness and bounce change before lines do.
- —Do not change your skincare routine at the same time or you will not know what did what.
Pairing it with weight loss
If you are running a GLP-3 RT protocol at the same time, GHK-Cu is doing damage control on the skin side while you lose fat quickly. Both pens together take AED 100 off automatically at checkout.
