Paul Mitchell's Tea Tree Scalp Care Anti-Thinning Tonic (now sold under the Scalp Care Regeniplex name) is a leave-on scalp spray designed to dissolve oily buildup and create a healthier scalp environment that supports fuller, thicker-looking hair over time. It's a scalp treatment rather than a hair-length product — it's sprayed directly onto the scalp and left in, not rinsed out.
The formula is built around Paul Mitchell's Regeniplex botanical complex, which combines Kakadu plum, pea peptides, clover flower extract, turmeric root extract, and ginseng root extract, alongside tea tree leaf water, biotin, panthenol, and niacin. In an 8-week clinical study cited by Paul Mitchell, 85% of participants reported increased hair volume and strength. It's color-safe, so it won't strip or fade hair color, and it's paraben-free.
