Hairderm CICA+PDRN Hair Ampoule is an advanced Korean scalp treatment designed to help support healthier-looking, fuller hair by targeting the scalp first.

While most hair products only coat the strands, Hairderm focuses on where healthy hair begins — the scalp and roots. Powered by CICA to calm visible irritation and PDRN to support scalp renewal, this concentrated ampoule helps reduce the look of dryness, soothe stressed scalps, and create the ideal environment for stronger, thicker-looking hair.

If your hair feels thinner, weaker, or more fragile than it used to, Hairderm delivers targeted care that helps bring your scalp back into balance so your hair can look healthier over time.

  1. After washing your hair, part it into sections and apply the ampoule directly onto the scalp.
  2. Focus on thinning areas, stressed spots, or anywhere your scalp feels dry or irritated.
  3. Gently massage with your fingertips until fully absorbed.
  4. Do not rinse.
  5. Use consistently for best results.

You're not imagining it.Your hair is changing.

Your part is wider than it was last year. Your ponytail feels thinner in your hand. You find strands on your pillow every morning. You avoid certain hairstyles. Certain photos. Certain lights.

It's not vanity. It's your scalp telling you something's wrong.

87% of thinning starts at the scalp — not the strands.

The truth nobody tells you:

Over 20,000 Women Already Made The Switch

6 weeks in and my postpartum hair loss has visibly slowed down. The brush applicator is genius — no greasy roots. Already on my second tube.

My hair was so flat and thin after my 40s hit me hard. 4 weeks with this and I actually have volume again. The serum doesn't make your roots greasy which was always my issue with other products.

Verified

Melissa T.

Stress was literally eating my hair. 5 weeks using this and the shedding has reduced so much. My scalp feels calm for the first time in years.

Verified

Carmen V.

Arrived in 6 days, packaged really carefully. I'm 52 and my hair was thinning badly on top. 3 weeks in and I can already see new growth filling in. Wish I'd found this sooner.

Verified

Isabelle M.

Tried everything for two years, nothing worked. Package showed up faster than expected, really well protected. Week 6 now and the shedding has basically stopped. Wore a ponytail last week for the first time in ages.

Laura K.

I've been using it for 7 weeks and this little strand is brand new – I'm really happy with it!! I'd definitely recommend it

Most users report a significant reduction in shedding within the first 2 to 4 weeks of daily use.

Because our formula targets follicle weakness and helps “anchor” the hair at the root, the first sign of success is usually a cleaner hairbrush and a clearer shower drain. Real restoration takes time, but the “stop-loss” phase often happens relatively quickly.

Not at all. Unlike traditional rosemary oils that sit on top of the hair and ruin your style, our Korean Scalp Serum is a water-light, non-greasy formula. It is designed
to absorb quickly into the scalp without leaving residue, so you can apply it to dry hair in the morning and go about your day with a fresh, clean look.

Most products try to treat the hair strands you already have. We treat the “soil”.


If your follicles are dormant due to poor circulation or a clogged scalp environment, vitamins may not effectively reach the root.

Our serum uses a specialized Korean activation complex to help reset the scalp environment and support dormant follicles, especially around sparse areas like the hairline and part.

We want you to feel the weight return to your ponytail and see those new sprouts at your temples.


Because hair growth cycles vary, we recommend using the serum daily for at least 60 days to give it enough time to show the full “sprouting” effect.


If you’ve stayed consistent and still aren’t seeing the results you expected, we offer a 60-Day Money-Back Guarantee. No stress, no risk.
