Thinning, limp, or easily weighed-down hair needs a conditioner that nourishes without coating. The Aromatica Rosemary Hair Thickening Conditioner meets that brief — a silicone-free, sulphate-free formula that repairs and volumises using plant-powered active ingredients rather than heavy synthetic polymers.

The headline is 53.6% Rosemary Leaf Extract, extracted using a decoction method — slow, low-heat extraction that preserves the full spectrum of rosemarinic acid, polyphenols, and essential oil actives. Rosemary has strong published evidence as a scalp stimulant, improving circulation to hair follicles and providing antioxidant protection against the oxidative stress that contributes to thinning. Pine Leaf Extract, Basil, and Oregano Leaf are extracted the same way and add cleansing, antimicrobial, and follicle-nourishing activity.

Organic Babassu Seed Oil (Orbignya Oleifera) and Organic Moringa Seed Oil provide rich fatty acid conditioning without heaviness — both penetrate the hair shaft for genuine moisture rather than surface film. Biotin (Vitamin B7) supports hair health and strength from the root. Panthenol (Vitamin B5) improves elasticity and reduces breakage. Bifida Ferment Lysate and Lactobacillus Ferment Lysate support scalp microbiome health. Caffeine adds further scalp-stimulating activity.

The result is hair that feels genuinely softer and lighter, with volume that builds over time rather than disappearing by lunchtime.

Aromatica is one of Sul Skin's favourite Korean clean beauty brands. This conditioner is a particular standout — it's vegan, silicone-free, and backed by a formula that rivals far more expensive options.
