Water-light scalp care, delivered directly through a built-in massage applicator.

Refilled Hair Recovery Cytokine Booster Pro is a leave-in scalp serum for a fresh, clean-feeling root routine without a greasy or sticky finish. The attached soft silicone applicator helps place the formula between the hair, then massages it across the scalp without requiring a separate tool.

• Direct scalp application: Short, soft silicone massage nubs help distribute the serum at the roots.
• Fresh surface care: Salicylic acid supports gentle removal of oil and buildup from the scalp surface.
• Cooling, lightweight feel: Menthol gives an immediate fresh sensation while the water-thin formula absorbs quickly.
• Hydration and comfort: Glycerin, panthenol and allantoin complement the clarifying base.

Who it suits

Best for normal, oily and combination scalps that want targeted leave-in care for buildup, excess oil or a flat-feeling root area. The formula contains alcohol, menthol, fragrance and fragrance allergens, so dry or reactive scalps should patch test before full use.

How to use

After shampooing, towel-dry the hair and scalp. Remove the black outer cap and gently press the attached silicone applicator directly onto the scalp, focusing on the desired areas. Massage until absorbed. Do not rinse. The retailer directions recommend use morning and evening on damp or dry hair.

Applicator note: The product uses a cluster of short silicone massage nubs attached to the bottle, not a narrow nozzle.
