Hair Root Infusion Serum Applicator Brush Bulk

This Scalp Revitalizing Serum pairs a 135ml soft-tube formula with a precision serum infusion brush — a dense-pin applicator with an ON/OFF flow control dial that channels serum directly through needle-fine pins deep into the scalp's root zone while simultaneously detangling and massaging the hair. Designed for consumers who want a salon-grade scalp treatment experience at home, this set delivers active ingredients at follicle depth with zero product waste and zero hand contact.
