The Ordinary Multi-Peptide Serum for Hair Density

The Ordinary Multi-Peptide Serum for Hair Density is a concentrated, ultra-lightweight leave-in scalp treatment formulated to support thicker, denser, & fuller-looking hair. Water-based & fast-absorbing, it applies cleanly without residue or greasiness, making it ideal for all hair types — including fine & colour-treated hair. Positioned as an affordable, clinically inspired alternative to high-end hair density treatments, it delivers a 21.15% total concentration of active technologies in a no-fragrance, vegan, & alcohol-free base.

This serum is designed exclusively for PM use. It is applied once daily to a clean, dry scalp at bedtime, allowing the actives to work overnight without interference from styling products or environmental stressors. Because it is a leave-in formula, it should not be rinsed out. Results typically require consistent daily use over a minimum of three months, with many users reporting reduced shedding within the first four weeks & gradual density improvements over several months.

The formula features six key technologies: REDENSYL targets scalp stem cells & fibroblasts to rebalance the hair growth cycle; Procapil combines Biotinoyl Tripeptide-1 with vitamin B to strengthen hair anchoring & combat DHT-related thinning; CAPIXYL pairs Acetyl Tetrapeptide-3 with red clover extract to inhibit DHT & support the scalp’s extracellular matrix; BAICAPIL uses botanical extracts to extend the active growth phase; AnaGain (Pisum Sativum Extract) supports follicle signalling; & High-Solubility Caffeine stimulates microcirculation to improve nutrient delivery to the follicle.

How to Use: Apply a few drops directly onto a clean, dry scalp once daily, preferably at bedtime. Massage thoroughly into the scalp using fingertips to aid absorption. Do not rinse out. Use consistently for at least three months for optimal results. Patch test prior to first use is recommended.
