Biolage Full Rescue Invigorating Scalp Serum is a leave-on scalp treatment for thinning hair that falls out from breakage. The dropper serum delivers the Full Rescue concentrate of steam-distilled rosemary oil and triple-purified niacinamide (5 micrograms per 50 ml, per the pack) directly where hair grows.
Biolage says it fortifies hair from root to tip, balances the scalp and helps neutralize free radicals, supporting healthier-looking growth and visibly thicker hair. The formula also contains caffeine, arginine, calcium pantothenate (vitamin B5) and pyridoxine (vitamin B6). Used with Full Rescue Shampoo and Conditioner, the brand reports +74% resistance to hair fall due to breakage from brushing, versus a non-conditioning shampoo.
Apply to towel-dried hair after shampoo and conditioner, one drop every inch along parted sections, then massage in. No rinsing. 1.6 oz (50 ml) bottle.
