With The Ordinary Multi-Peptide Hair Serum, there’s really only one question everyone wants answered. Does it work?

Some people (see reviews below) absolutely love and will say it works and others will say it did nothing. For those it did nothing for – were they consistent? Did they really use it as instructed and persevere with it? I could easily say it didn´t work, but the truth is I wasn´t consistent. I started using it but then a friend bought me the Olaplex System so I am currently using The Ordinary Multi-Peptide Serum on my eyebrows and will report back soon.

I don’t have hair loss but my hair is very fine and I find that the multi-peptide serum it does give volume and makes hair look healthy.

I started using The Ordinary Multi-Peptide Hair Serum on my brows and bald patches started to show some new hair growth. My brows are looking so much fuller!

I liked this serum! It works amazing if you have an itchy or irritated scalp. It balances it out and gave me a few new baby hairs as well.

I wasn’t consistent and it worked for me. Had I not taken before and after photos or I wouldn’t have believed myself.

The Ordinary Multi-Peptide Hair Serum has totally worked for me. I run the tip down each side of my head and some at the crown and then brush with a massaging brush. I have noticeable hair growth.

The Ordinary Multi-Peptide Hair Serum Box, Bottle & Serum

For anyone worried if they have bought a counterfeit product, here are photos of The Ordinary Multi-Peptide box, bottle and serum. The serum is quite watery, it rubs into the skin on the back of my hand quite nicely. It absorbs very well and leaves it feeling smooth, not oily.

Where to buy The Ordinary Multi-Peptide Hair Serum

Buy from Deciem or one of the many authorised stockists online. If you purchase from Amazon, Ebay, Shopee there is no guarantee of the products being authentic.

Other hair products

Deciem also has HIF for hair which you could look at and find reviews in the Facebook Group or on Instagram. If you´re looking for something to repair hair, then I would look at Olaplex. A friend of mine loves it and bought me a mini-set for Christmas. First impressions are that it´s amazing. It’s a bit of a chore having to damp the hair and leave products on for a while but it’s worth it. Hair feels so much stronger yet softer. You can buy through Look Fantastic and sometimes the Deciem Chat Room codes work too, but they often have 20% off.
