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 6–8 drops of 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.

Sarah M. · Verified Customer
"I've had scalp psoriasis for 11 years. I've tried every steroid cream going and nothing lasted. After 6 weeks with Derval, my scalp is the calmest it's been in a decade. I actually wear my hair down now."
★★★★★
James T. · Verified Customer
"My dermatologist mentioned copper peptides as something worth trying. I found Derval and within a month the constant itching had basically stopped. The coal tar shampoo was embarrassing and this is so much better."
★★★★★
Priya K. · Verified Customer
"I was sceptical — I've been let down by so many products. But honestly, after 3 months I had my first totally clear week. My scalp psoriasis hasn't gone entirely but the severity has dropped massively."

Your 90-Day Journey to a Calmer Scalp
