About this product
Looking for a scalp tonic for thinning hair that fits a daily routine? This multi-peptide serum for hair density from The Ordinary is a lightweight leave-in scalp serum, applied in drops, that helps improve the look of fuller-looking hair. It lists peptide technologies REDENSYL, Procapil, CAPIXYL, BAICAPIL and AnaGain, plus high-solubility caffeine and plant extracts including Larix Europaea wood extract, Pisum Sativum extract and Camellia Sinensis leaf extract.
Texture, format and finish of the serum
The format is a liquid serum rather than a cream, oil or spray tonic, and it is designed to stay on the scalp with no rinse step. The brand describes it as concentrated yet lightweight, so the finish is intended to be non-greasy at the roots. Application is by drops straight from the bottle, which lets you place the product along the part, temples or crown rather than through the lengths. Because it is a leave-in, it sits at the front of your routine on the scalp itself, before styling. The formulae is listed as cruelty-free, gluten-free, vegan, alcohol-free and silicone-free. No scent is named in the product data, so check the carton if fragrance matters to you.
Where this serum fits in a scalp routine
If your main concern is how the hair looks along the part line, a leave-in scalp serum is one option to weigh against a tonic, spray or ampoule. This one goes on the scalp rather than the hair, so you part the hair and work in sections. The stated directions are a few drops on a clean, dry scalp once daily, preferably at bedtime, which suits a routine where the serum sits overnight. The product data does not give a measured amount in millilitres or a stated duration for how long one bottle lasts, and no product size is specified, so follow the on-pack directions and adjust the number of drops to cover the areas you want to reach.
What the ingredient list shows
The declared peptide technologies are REDENSYL, Procapil, CAPIXYL, BAICAPIL and AnaGain, alongside high-solubility caffeine. Plant-based extracts named in the listing are Larix Europaea wood extract, Pisum Sativum extract and Camellia Sinensis leaf extract. This is a cosmetic scalp product, not a licensed drug or NHP, and no DIN or NPN is stated in the product data. The full INCI list is not included, so read the packaging for the complete ingredient declaration if you are checking for a specific component.
How much to use per application
The stated directions are a few drops applied to a clean, dry scalp once daily, preferably at bedtime. There is no rinse step and no measured dose given in millilitres. Part the hair, place the drops where you want coverage, and work along the scalp rather than the ends.
