Key Ingredients
Key Ingredients
PDRN (Polydeoxyribonucleotide) — the K-Beauty clinic favourite. A regenerative, DNA-derived ingredient that supports skin repair around the follicle, creating a healthier environment for growth.
Rosemary Leaf Extract — studied for its ability to support circulation in the scalp and promote thicker, denser-looking hair over time.
Caffeine (10,000 ppm) — a high-strength dose that wakes up flat, tired roots. Helps hair at the scalp look lifted, fresh, and full of life.
Lightweight Hydrating Base — water-light texture that soothes dryness and flaking without weighing hair down or leaving residue.
See packaging for the full ingredient list.

THE REAL PROBLEM
Your hair isn't the problem. Your scalp is.
Most hair products coat the strand and ignore the root. But thinning starts underneath — follicles fall dormant when the scalp is inflamed, dry, and undernourished.
The fix: PDRN, the regenerative molecule used in Korean skin clinics, repairs the scalp environment while rosemary stimulates circulation to the follicle. Healthy scalp in, fuller hair out.

How To Use It
Four simple steps, once a day. Most users see the best results after 6–8 weeks of consistent use.

1
STEP 1
Part Your Hair
Start with a dry or towel-dried scalp. Part your hair to expose the areas you want to treat — crown, hairline, or anywhere thinning shows.
-
2
STEP 2
Apply The Serum
Dispense 1–2 droppers directly onto the scalp along your part lines. A little goes a long way — focus on the roots, not the lengths.
-

STEP 3
Massage For 60 Seconds
Gently massage with your fingertips. This boosts absorption and stimulates circulation — the perfect partner to rosemary's follicle-waking effect.

STEP 4
Leave In — That's It
No rinsing, no residue. Style as usual. Use once daily — morning or night — and let consistency do the work.

PDRN Serum FAQ's
How long until I see results?
How long until I see results?
Most users notice a calmer, healthier scalp within the first week. New baby hairs typically appear around weeks 3-6, with visibly fuller density at 8-12 weeks of consistent daily use. Hair growth is a cycle — consistency matters more than anything.
Will it make my hair greasy?
Will it make my hair greasy?
No. The serum is water-light and absorbs into the scalp in seconds. There's no oily residue, no buildup, and no need to rinse — you can style your hair as usual right after applying.
What exactly is PDRN?
What exactly is PDRN?
PDRN (polydeoxyribonucleotide) is a DNA-derived regenerative ingredient made famous by Korean dermatology clinics, where it's used to repair and rejuvenate skin. Applied to the scalp, it supports a healthier skin environment around the follicle — the foundation for fuller-looking hair.
How often should I use it?
How often should I use it?
Once daily — morning or night, whichever fits your routine. Apply directly to the scalp, massage for about 60 seconds, and leave in.
Is it safe for sensitive scalps and color-treated hair?
Is it safe for sensitive scalps and color-treated hair?
Yes. The formula is designed to be gentle and is applied to the scalp, not the lengths, so it won't affect your color. As with any new product, we recommend a small patch test first if you have very sensitive skin.
How long does one bottle last?
How long does one bottle last?
With daily use, one bottle lasts around 4-6 weeks. Since visible results build over 8-12 weeks, most customers start with two or three bottles so they don't run out mid-progress.
What if it doesn't work for me?
