Revitalise thin, lacklustre locks with The Ordinary’s Multi-Peptide Serum for Hair Density, a concentrated serum designed to promote healthier looking hair. Known for its strong focus on effective ingredients and innovative formulas, the brand has enriched this leave-on serum with potent botanical extracts which encourage thickness and fuller-looking hair. The formula also includes a peptide complex to help replenish hair follicles and minimise hair loss, whilst caffeine stimulates the hair, supporting growth and healthy hair. This trio of ingredients is combined in an emollient base, which aims to penetrate the scalp and replenish hair from root to tip. To use, apply a few drops at night to a clean, dry scalp for a leave-on, overnight treatment. The lightweight serum prevents hair feeling greasy or weighed down, meaning it doesn’t need to be washed out after use. The product is enclosed in a recyclable and UV-protected dropper bottle to preserve the ingredients and ensure the effectiveness of the serum. Free from alcohol, silicone and allergens. Cruelty-free and vegan.
