The Ordinary Multi-Peptide Serum for Hair Density

A leave-in scalp treatment built on a stack of peptide complexes with caffeine, larch tree extract and a blend of amino acids, aimed at hair density and thickness rather than at the hair shaft. It is applied to the scalp, not the hair, and it is a slow product -- the published testing runs over months, not weeks. Vegan and cruelty-free. This is the one product in the range with no cheaper local equivalent, which is why it holds its price in Bangladesh.

Apply to a dry or damp scalp once daily, ideally at night. Part the hair in sections and use the applicator directly on the scalp, then massage in with the fingertips. Do not rinse out. Give it a minimum of three months before judging results.

Caffeine, Larch Tree Extract, REDENSYL, Procapil, Capixyl, Baicapil, Acetyl Tetrapeptide-3, Copper Tripeptide-1, Glycerin, Pisum Sativum (Pea) Sprout Extract.

Ingredient lists are transcribed from the packaging of the batch we hold. Manufacturers reformulate — always read the carton you receive, and patch test if you react easily.

Check the batch code and expiry first. On a genuine unit both are printed or embossed directly into the carton and the container rather than added on a stuck-on label, and the two match each other. The seal should be intact and machine-applied, the pump or dropper should move cleanly and firmly, and the ingredient list on the pack should match the one shown on this page. Texture and smell are worth a moment too: a thinner, more strongly perfumed version of a familiar product is a common sign of a copy. We photograph every unit as it arrives and record its batch code and expiry from the carton, so the item you receive is the one we checked. If anything does not match, send us photographs before you use it and we will sort it out with you.

• This one is a pre-order. We buy it in the United States for you and bring it over with our next shipment — normally about two to three weeks. That is an estimate, not a promise: we give you the date we expect when you order, and tell you if it moves.
• In and around our own area we deliver ourselves. Anywhere further goes by courier, and you are welcome to collect from us instead.
• The delivery charge is quoted and paid up front, never added afterwards. The rest is paid when the item reaches you.
• Damaged, incorrect or expired: tell us within 7 days with a photograph and we replace it on our next shipment — or refund you if we cannot. See our delivery and returns policy.
