Dr. Rachel Harlow
"I've seen patients reduce steroid use significantly after adding copper peptides to their routine. GHK-Cu addresses the barrier dysfunction that steroids simply don't reach."
1
Part your hair
Apply serum directly to the affected areas of your scalp. Work in sections to ensure full coverage.
2
Massage in
Use your fingertips to gently massage the serum into the scalp for 60 seconds. This boosts circulation and aids absorption.
3
Leave overnight
No rinse required. The lightweight formula absorbs fully and works while you sleep. Apply to dry or slightly damp scalp.
💡 Best results: use nightly before bed
4
Use consistently
Apply every night for best results. Most customers notice reduced itch within 1–2 weeks and visible improvement by week 4.
How long before I see results?
Most customers notice reduced itch and tightness within 1–2 weeks. Visible reduction in flaking typically occurs by week 3–4. Significant improvement is usually seen after 8–12 weeks of consistent daily use.
Can I use it alongside my prescribed treatments?
Derval is steroid-free and made with cosmetic-grade ingredients. Most customers use it alongside their existing routine. We recommend consulting your GP if you are using topical steroids or prescription treatments.
Is it suitable for all hair types?
Yes — the serum is lightweight, non-greasy, and works across all hair types including fine, thick, curly, colour-treated, and natural hair. It is fragrance-free and suitable for sensitive skin.
Do I need to rinse it out?
No. Derval is a leave-in serum. Apply at night, massage in, and leave it to absorb. It won't leave residue on your pillow or feel greasy by morning.

The problem
Your scalp stopped protecting itself
There's a thin outer layer on your scalp that keeps moisture in and irritants out. When it weakens, it doesn't simply bounce back. Everyday things get through, the skin stays irritated, and you end up scratching without noticing.
That's why the flakes are back two days after washing. Why the itch never quite settles. Why there seems to be more hair in the brush than there used to be.
The solution
A scalp serum built for the barrier
2% GHK-Cu. One job: help the barrier hold.
Lift what's built up
Flakes sit on top of the scalp and stop anything reaching skin. 0.5% salicylic acid gently lifts them, so the rest of the formula gets where it needs to be.
Calm what's irritated
Niacinamide and panthenol hold moisture in and help a tight, itchy scalp feel comfortable. Less irritation means fewer reasons to reach up and scratch.

Your 90-Day Journey to a Calmer Scalp
GHK-Cu works progressively — the longer you use it, the more your scalp resets
Week 1–2
Soothe & Stabilise
GHK-Cu begins reducing surface inflammation. Itch typically eases within the first 2 weeks. Scalp feels less tight.
Week 3–4
Visible Reduction in Flaking
Salicylic acid and GHK-Cu work together to lift scale. Redness visibly reduces. Scalp feels cleaner and more balanced.
Month 2

Skin barrier function improves significantly. Flare-ups become less frequent and less intense. Hair appears healthier.
