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

The truth is that some people absolutely love it and say it works, whilst others will say it did absolutely nothing. For those who say 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 cannot provide you with a review because I wasn’t consistent, but I will give it another go. When I did use it, I felt my hair look unwashed and greasy the next day, meaning I had to keep washing it. My hair is really fine.

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

The Multi-Peptide Hair Serum – I started using on my brows, and bald patches 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 balanced 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 purchased from Deciem. 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.

Hair Loss

When it comes to hair loss, there could be many reasons. It’s best to check with a professional and maybe get your blood checked. I lost a lot of hair after surgery and when I had anaemia. It slowly grew back once my body recovered. I picked up some great tips from the Curly Girl Method (Facebook Groups), using some of the recommended shampoos, plopping (wrapping hair up in a microfibre towel), using less heat and no heat at all through the summer months. The more I worried, the worse it became.
