Divi Scalp Serum for Thinning Hair, 15ml — Caffeine & Rosemary

Divi Scalp Serum is a lightweight, dropper-based scalp treatment formulated with amino acids, caffeine, and rosemary oil to address thinning hair and scalp health. The serum targets reduced oil buildup and product accumulation while promoting circulation for a fuller-looking appearance. Positioned as clinically tested, it appeals to users seeking a non-greasy scalp treatment rather than a heavy oil. The 15ml size suits travel and sampling, though coverage for regular scalp massage is limited. Growth claims are clinically supported (a rarity in this category), though results remain primarily anecdotal in community reviews. Best suited for fine, oily, or product-prone scalps seeking lightweight hydration without greasiness.
