Lightweight Scalp-to-Strand Care for Fuller-Looking Hair
medicube Rosemary PDRN Hair & Scalp Conditioner is a lightweight conditioning treatment designed for dry, fine, weak-feeling, or flat-looking hair. Combining Rosemary Extract, PDRN, and a 19 Amino Acid Complex, it helps hydrate, smooth, and detangle hair while supporting a comfortable-feeling scalp and fuller-looking volume. Its scalp-to-strand approach makes it a versatile addition to a hair-care routine focused on softness, manageability, and healthy-looking hair.

Rosemary Extract & PDRN for Scalp Care
Rosemary Leaf Extract is a botanical ingredient used to condition and refresh the scalp, while PDRN (Sodium DNA) is included as part of the formula’s scalp and hair-care system. Together with moisturizing and conditioning ingredients, they help maintain a comfortable-feeling scalp and support healthier-looking hair. These cosmetic benefits should not be confused with proven treatment for hair loss or guaranteed hair growth.
19 Amino Acid Complex for Softer, Smoother Hair
Amino acids are important components of hair’s natural protein structure. The formula’s 19 Amino Acid Complex helps condition the hair, improve smoothness, and make strands easier to manage. The blend includes amino acids such as Alanine, Arginine, Aspartic Acid, Glutamic Acid, Glycine, Histidine, Isoleucine, Leucine, Lysine, Methionine, Phenylalanine, Proline, Serine, Threonine, Tryptophan, Tyrosine, and Valine, helping support softer-feeling hair and easier detangling.
Hair Strength & Breakage Care
Dryness and tangling can make hair difficult to manage and contribute to breakage during brushing. Conditioning agents help smooth the hair surface, improve manageability, and support stronger-looking strands. Regular conditioning can make hair easier to comb and style, although results depend on hair condition and styling habits.
Lightweight Volume Without a Heavy Finish
Fine hair can easily feel weighed down by rich conditioners. This lightweight formula helps soften and detangle the hair while maintaining natural-looking volume, making it particularly suitable for fine, flat, or easily weighed-down hair. It helps hair look smoother and more polished without relying on a heavy coating to create shine.
Hydration from Scalp to Ends
Glycerin, Panthenol, Hydrolyzed Hyaluronic Acid, and Sodium Hyaluronate help maintain moisture and improve the feel of dry hair and scalp. These moisturizing ingredients work alongside conditioning agents to leave hair softer, smoother, and more manageable. The result is a conditioning routine that combines moisture care with lightweight softness and a refreshed feel.
Refreshing Scalp Sensation
Menthol, Rosemary Oil, and Peppermint Oil contribute to a refreshing sensory experience during application. However, cooling sensations do not necessarily indicate improved scalp health, and botanical oils or fragrance components may not suit everyone. Those with fragrance-sensitive or easily irritated scalps should review the ingredient list and patch test before use.
Reported Hair-Care Test Results
According to medicube’s reported product testing, the conditioner demonstrated a 38.12% improvement in hair-breakage strength after four weeks, a 63% reduction in the appearance of visible flakes after one use, a 44.07% improvement in hair softness, and a 22.27% improvement in hair volume. These figures reflect the brand’s testing conditions and should not be interpreted as guaranteed results for every user.
How to Use
After shampooing, apply the conditioner to wet hair and scalp according to the product directions. Gently massage through the hair, from the scalp toward the lengths and ends, leave on for 1–2 minutes, and rinse thoroughly with lukewarm water. Use regularly as part of your hair-care routine. For a coordinated routine, pair it with medicube Rosemary PDRN Shampoo or Rosemary PDRN Scalp Serum, if available.
Perfect For
This conditioner is particularly suitable for fine or flat-looking hair, dry and weak-feeling strands, hair prone to tangling and breakage, and hair lacking softness or shine. It may also appeal to those looking for a refreshing scalp-care experience alongside lightweight conditioning. If irritation develops, discontinue use.
Formula Note: The product is described as free from parabens, silicones, sulfates, and silicone oils. Individual sensitivities can vary, so review the full ingredient list before use.
