The 12-peptide complex is the signature peptide blend the product is named for. Peptides are short chains of amino acids used in scalp treatments to support the scalp and the hair growth environment. In this filler the peptide complex works alongside copper tripeptide-1, the exosome complex and hyaluronic acids.

It is the product’s exosome component – a plant-derived exosome complex. Exosomes are tiny extracellular vesicles that act as messengers between cells and are used in scalp care to support communication within the scalp environment. The “3D” naming is the brand’s term for its exosome complex.

Hyaluronic acid is a strong humectant that holds moisture. Including multiple hyaluronic acids in the filler is intended to hydrate and condition the scalp environment, which can become dry or compromised, so the exosomes and peptides act on a better-balanced scalp.

The filler is the in-clinic treatment step, while the matching HAIRIZ 3D scalp-care shampoo is a take-home product for daily maintenance between treatments. Used together they form a treat-and-maintain routine for the scalp.

It is intended for use by trained medical and aesthetic professionals on the scalp, not for self-administration. It should be avoided in pregnancy and breastfeeding, in anyone with known allergy to its ingredients, and on areas with active scalp infection. Patient suitability is assessed by the treating professional.
