Divi Scalp Serum for Thinning Hair – Peptide & Rosemary, 30ml

Divi Scalp Serum for Thinning Hair is a 30ml (2x15ml pack) peptide and botanical serum targeting scalp health and the appearance of fuller hair. Formulated with amino acids, caffeine, and rosemary oil, it claims to promote scalp circulation, reduce oil and product buildup, and support hair density. Applied via dropper to the scalp, the serum targets those with thinning or fine hair seeking lightweight scalp stimulation without heavy oils.

Active ingredients include a peptide-caffeine-rosemary blend, positioning it between a pure botanical oil (like Mielle) and a clinical serum (like The Ordinary). Clinical testing is mentioned but details are sparse in retail copy—growth claims lean anecdotal. Community feedback suggests it soothes and hydrates scalp without greasy buildup, making it suitable for fine/thinning hair types. At $40/oz, it sits in the mid-premium range. Some reports of occasional dropper inconsistency. Divi has a growing but modest brand presence in scalp-care circles.
