This product saved me!!
A while ago, I noticed a patch of my hair missing out of the blue. I got tested and everything came back fine. So I ordered this product in hopes it would bring my hair back. The first photo was from January 28th and the spot was very very bare with no hair at all. The photo is pretty bad but trust me, it was bare and big. The second photo was from February 14th and after just a couple weeks there was hair starting to grow. Very faint but it was there. The third picture was from March 4th and there is definitely growth but still not full yet. The fourth picture is from March 30th. It’s definitely still there but much much more hidden. The final photo is where i’m at now. I can tell where my old spot was, but it’s all better now. I also included a photo of how long it has gotten as well. Before I started using this product my hair was not growing. I am so greatful for this product and I cannot recommend it enough.

A Solid Supporting Serum for Hair Density and Strength
I wanted to share a positive review of The Ordinary Multi-Peptide Serum for Hair Density. The photo attached shows my two-month results, achieved using this serum alongside other hair-growth products, including minoxidil. While this peptide serum won’t deliver dramatic results on its own, I truly believe it plays an important supporting role in a hair growth routine. The science behind the ingredients is solid. Peptides act as cellular messengers, encouraging scalp cells to repair, regenerate, and remain in the active growth phase longer. Copper peptides, in particular, help stimulate hair follicles, promote scalp health, and can even increase follicle size, often resulting in thicker strands and improved density. This serum also includes botanical complexes such as Redensyl, which support scalp circulation and help extend the growth phase. There are many other beneficial ingredients I won’t dive into here, or this review would get far too long but the bottom line is this serum is supportive, not miraculous. Results are gradual, but absolutely worthwhile with patience and consistency. I apply it about 30 minutes after using minoxidil each day, and I’ve found that routine works well for me. If you’re on a hair-growth journey, this is a great product to incorporate into your regimen.

Still waiting on results
Long story spent a year and 3 months having teeth pulled and dental implant abutments put inside my gums.This stress if so much novocaine and many dental treatments caused my already thinning hair go into telogen effluvium. So I deeply panicked im a veteran with ptsd and anxiety so I completely shut down .I now have a giant bald spot on left side of my head that moved frontal you can see thru my entire left side of my scalp. My hair is almost to my tailbone .I have no thyroid and of course means hypothyroidism is always to blame. I bought 6 bottles as my thinning is my whole scalp and a couple drops is not cutting it .I needed more per use.Ive been extremely faithful in use put on at evening and wash out next day. So far its been 4 months no new growth anywhere no baby hairs nothing filled in. However after 5 weeks it stopped my telogen effluvium I lose about 35 to 40 a day .I was shedding 100s giant piles of hair prior.So it did curb the shedding alot. I also have extreme thin eyebrows been using it on my eyebrows too but so far no new growth or darker . I purchased here and ulta so im going to use a year faithfully and see if I get any better results My teeth are all done and that stress is now over nothing I've done so far has worked I've tried hard to regrow hair but im 62 and no thyroid . I'd say I've benefited from less fall out but no new growth

Easy to Use & I’m Seeing Hair Growth!
⭐️⭐️⭐️⭐️⭐️ I’ve been using The Ordinary Peptide Serum for about 6 months now and I’m really happy with it. I’ve actually noticed new hair growth, especially in areas where my hair was looking a little thinner. I love how easy it is to use. I just apply it to my scalp before bed and leave it overnight, so it fits perfectly into my nighttime routine without adding much extra time. I’ve been consistent with it and feel like the results have been worth it. Definitely a product I plan to keep using!

Part of a multi-prong approach that works.
I have been battling hair loss for years and have gradually increased my knowledge (and thickened my hair dramatically) over that time. Most notably, in the last 2 years, I have waged an all-out war on hair loss and I can truly say today that I won! I no longer have thin hair, bald spots, or an embarrassing hairline. My hair is as thick as it was when I was a teenager, 50+ years ago. Hair loss is not a one-and-done problem. It takes hitting it on all sides to combat it. For me, what I have found that works is frequent hair washing with a caffeine-based shampoo, lots of 5% minoxidil (and I mean a lot all over my scalp), oral minoxidil (from Musely), and the final nail is this Ordinary Multi-Peptide Serum. Before starting it, I had excellent results everywhere except one area on my left upper temple that stayed stubbornly thin. Within 2 months of starting the Ordinary Multi-Peptide Serum, that area filled in completely.

The Oridnary Hair care will help with hair thickness and some regrowth
I have now finished 2 full bottles of this and can say that my hair definetly feels thicker and stronger. I'm not sure on how it's helping with shedding though as I'm terrible with keeping up with that. I have noticed more baby hairs and hair seems to have grown faster by the gray hair I now have!

Worth Trying for Thicker-Looking Hair
I’ve been using this serum for about a month, applying it twice a week, and I’m genuinely happy with the results so far. My hair looks a little fuller and healthier, and I’ve noticed some improvement in areas that seemed thinner before. The serum is lightweight, easy to apply, and doesn’t leave my scalp feeling greasy. I know hair growth takes time, so I wasn’t expecting instant results, but based on my experience, I think it’s a good value for the price and I’m looking forward to seeing the results with continued use.

Muy bueno
Es muy bueno! Me lo echo de vez en cuando en la raiz y huele bien, no arde ni pica. Eso si, hay que echarselo en la raiz, si toca mucho el pelo alrededor puede dejar una apariencia como grasosa pero no es demasiado.

I am on my second bottle and have definitely noticed a difference.
I have very thin, fine hair which has been thinning at my temples in recent years. After reading many articles I decided to try this serum as it was consistently highly recommended. I haven’t been disappointed. The first bottle lasted about 6-8 weeks and in that time I have noticed hair thickening at my temples and lots of baby hairs growing around my hairline generally. I honestly wasn’t expecting results so fast. I use the product at night and it truely does dry non-greasy - by morning I can’t tell I used it. The smell is strong, but not unpleasant and I quickly got used to it.
