What's New: A Glass Oil for the Rosemary PDRN Line
The Rosemary PDRN line already includes the Cooling Thickening Shampoo (400ml), Hair & Scalp Conditioner, Scalp Serum (20ml) and Damage Care Hair Mask (200ml). The Silk Hair Oil is the first leave-in finishing step in the line. Amazon labels it Korean hair care and says it "adds shine". According to medicube, it offers:
- Damage care: smooths frizz and roughness for instant softness, with a finish that doesn't feel heavy or oily.
- Heat protection up to 464°F / 240°C: protects hair from blow-dryers, flat irons and curlers. medicube says this was clinically tested by P&K Skin Research Center and that results may vary with hair condition and routine.
- Rosemary PDRN bonding care: pairs PDRN with 31 proteins and amino acids to help strengthen damaged cuticles.
- Frizz control: medicube reports +138.53% improved frizz control in hot and humid conditions after one use, based on the brand's own clinical testing.
medicube says the oil is formulated for straight, wavy, curly and coily hair, including fine and colour-treated hair.
Rosemary PDRN Silk Hair Oil Scent Notes
According to medicube, the Bergamot Musk fragrance has three layers of notes:
- Top notes: bergamot and lemon
- Middle notes: apple, nectarine and white rose
- Base notes: white wood and white musk
The scent moves from citrus top notes through fruit and white rose to a white wood and musk base. medicube's Amazon listing describes it as "a fresh, cozy scent blending bright bergamot with soft white musk".

What Makes the Rosemary PDRN Silk Hair Oil Different?
- It is the first leave-in finishing step in medicube's Rosemary PDRN hair care line, following the shampoo, conditioner, scalp serum and hair mask.
- medicube claims heat protection up to 464°F / 240°C, clinically tested by P&K Skin Research Center.
- The formula pairs PDRN (Sodium DNA) with 31 proteins and amino acids in a silicone-based glass oil.
It is one of several leave-in hair launches this autumn, alongside the Pantene Abbey Yung Deep Nourishing Transforming Cream to Mist Spray, which also arrived in the US in September 2026. Heat protection and frizz smoothing are also two of the three steps in the K18 Repair, Protect, Smooth Holiday Set.
Formula and Packaging
The oil comes in a spray bottle. Its first three ingredients are dimethicone, isododecane and dimethiconol. The formula also contains argan oil, rosemary leaf oil, Sodium DNA (PDRN) and a protein and amino-acid complex. Amazon lists the package as 5.16 x 2.05 x 2.05 inches and 5.29 ounces.
How to Use
medicube says to apply an appropriate amount to wet or dry hair, focusing on damaged areas. For a smoother finish, it says to apply more to the mid-lengths and ends after blow-drying. The brand also suggests pairing the oil with the Rosemary PDRN Hair Mask for extra bonding care.
