The OrdinaryMulti-Peptide Serum for Hair Density
Highlights
This concentrated vegan serum densifies and thickens hair to leave it looking healthier.
The formula contains several technologies in high concentrations.
Directions
Apply a few drops once a day, preferably in the evening, to a clean, dry scalp.
Carefully massage your scalp to help the serum absorb. This is a leave-in formula. Don't wash your hair or scalp after use.
If irritation develops, stop using and contact a doctor. Only use as indicated. We recommend doing a skin test before use. For a detailed guide to the skin test process, see DECIEM's website.
Keep away from children.

Not sure how effective it is
I saw a lot of hype online about this product, but I am not sure if it works. the texture is a bit oily and it makes my scalp greasy so it's kinds annoying touse it every day. I haven't seen change in hair growth so far.

Good price, nice ingredients
Really great price and I might still buy again, but leads a little bit of a residue and therefore difficult to use consistently. There are other serums on the market, which I prefer, but the ingredients are good and price is tough to beat. I’m not sure how effective the serum itself is versus regular scalp massage.

Not for me!
I really wanted to love this hair serum but it makes my hair so greasy! I’ve used it 3 days in a row and by the third day I’ve needed to wash my hair again which is not normal for me. I can usually leave my hair for up to a week once washed normally. Unfortunately I won’t be continuing to use due to this. I do have quite thin hair so maybe it’s just not suitable for my hair type ☹️

Great daily scalp serum. Lightweight and doesn’t leave your hair feeling greasy and moisturises the scalp really well.

Can I leave it on overnight
Hi! Yes this is classed as a leave in treatment
Date published: 2026-03-25
can it be used on eyebrows?
I use it on my eyebrows, but not on the eyelashes. I've noticed an improvement on my brows, but the consistency is the key, otherwise the effect goes away.
