Peptide Labz has upgraded its Advanced Hair Growth & Strengthening Serum Spray with the addition of licorice root extract, known for its soothing and scalp-supporting properties. The formula combines powerful peptides like acetyl tetrapeptide-3 and biotinoyl tripeptide-1, along with biota orientalis leaf extract and caffeine, to promote thicker, stronger, and healthier hair. Designed for daily use, the serum targets hair thinning at the root, strengthens follicles, and supports a healthy scalp environment.
