Korean dermatology meets everyday hair care. Stronger roots, calmer scalps, and visibly healthier hair begin here.
Medicube has done something very few brands attempt. Instead of releasing another “nice-smelling” shampoo or a lightweight conditioner that promises shine, they have created a complete, clinically inspired hair-loss system built around one of Korea’s most advanced regenerative ingredients: PDRN.
If you have been dealing with shedding, thinning, scalp irritation, or the slow loss of volume over time, this launch was made for you.
The new Rosemary PDRN Cooling Thickening Shampoo, Hair and Scalp Conditioner, and Scalp Serum work together to reset the scalp, support follicle strength, and improve the overall health of your hair from the root outward.
This is not a trend. It is the next chapter of Korean trichology.
Why PDRN is changing the hair-loss conversation
PDRN has long been used in Korean dermatology clinics to repair damaged skin and accelerate cellular recovery. When applied to the scalp, it supports a more stable environment for hair growth by reducing inflammation, improving hydration, and reinforcing the structures that keep each follicle anchored.
Medicube took this clinic-level ingredient and placed it into a daily routine anyone can use at home.
The result is a three-step system that addresses every major contributor to hair loss: heat, buildup, inflammation, weakened follicles, and poor circulation.
Step 1: Rosemary PDRN Cooling Thickening Shampoo
Deep cleansing. Follicle renewal. Scalp relief.
The foundation of any hair-loss routine begins with clearing the scalp.
This shampoo cleanses without stripping, removing oil, sweat, dead skin, and styling residue that often clog follicles and interrupt normal growth. Low-irritant cleansers keep the barrier protected while salicylic acid gently exfoliates buildup.
What makes it different is the cooling complex. Menthol and menthyl lactate instantly lower scalp heat, a major cause of inflammation-driven shedding.
It also includes caffeine, niacinamide, arginine, biotin, and hydrolyzed proteins to energise follicles and support stronger, thicker hair over time.
Who should use it: Oily scalps, itchy or inflamed scalps, early thinning, heavy shedding, or anyone who wants a cleaner, fresher root lift.
Step 2: Rosemary PDRN Hair and Scalp Conditioner
Lightweight hydration that strengthens, soothes, and supports healthy growth.
This is not a traditional conditioner. It does not coat the hair with heavy silicones or oils. Instead, it nourishes both hair and scalp using restorative actives.
PDRN helps support cellular repair, while hydrating hyaluronic acids soothe sensitivity and prevent moisture loss. Caffeine, biotin, and niacinamide support circulation and follicle strength. A blend of herbal extracts, including rosemary, tea tree, and peppermint, calms irritation and refreshes the roots.
Hydrolysed plant proteins and amino acids repair the cuticle, improving texture, softness, and resilience.
The result is smoother, stronger hair that feels light and breathable at the roots.
Who should use it: Weak or brittle hair, sensitive or flaky scalps, hair that breaks easily, or anyone who wants hydration without weight.
Step 3: Rosemary PDRN Scalp Serum
A concentrated treatment for thinning, irritated, or stressed scalps.
This serum is the heart of the system. It absorbs instantly into the scalp and delivers a high concentration of PDRN, growth peptides, caffeine, and soothing botanicals directly where they are needed most.
If your scalp feels hot, tight, itchy, or inflamed, the cooling effect provides immediate comfort. Over time, PDRN and peptides support stronger follicle anchoring, improved density, and a healthier growth cycle.
Light as water. No stickiness. No residue. Just a calm, refreshed scalp and roots that feel alive again.
Who should use it: Anyone experiencing visible thinning, widening parts, chronic shedding, scalp sensitivity, heat, or buildup-related irritation.
How this three-step system works
Most hair-loss routines only focus on the hair fibre. Medicube focuses on the scalp, where the real problem begins.
Together, the shampoo, conditioner, and serum:
• Reduce shedding by clearing clogged follicles and calming inflammation
• Support long-term growth with PDRN and biomimetic peptides
• Improve circulation for better nutrient delivery
• Strengthen strands with proteins and amino acids
• Balance oil and hydrate the scalp
• Provide immediate relief from heat and irritation
• Create a stable, healthy scalp environment for thicker, fuller-looking hair
This is the closest you can get to Korean clinical scalp care in your daily shower routine.
