Effective Product at a Great Price!

When I lost a bunch of weight, I lost a bunch of hair too. To help remedy this problem I tried so many different things. Some products didn’t work, some left my hair feeling oily, sticky or crunchy and another one that really worked was $150 per month which was unsustainable. The reviews on this product were good so I gave it a try along with a rubber type brush to stimulate blood flow and spread the product. I have been using it for two months now and yesterday someone actually told me that I have thick hair! This product contains effective ingredients, it is not sticky or oily and most importantly it works really well at helping to thicken and regrow lost hair. It comes with a dropper and it is a clear liquid. No strong smell and easy to distribute on the scalp with no irritation. Not only does it work but it has an excellent price point. I will continue to use this hair product and I very highly recommend. Read more

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. Read more

Pleasantly surprised — will update after more time

I'm only about 3 weeks in, so I want to be upfront that this is an early impression — but I'm already noticing less hair in the shower drain and on my brush, which is honestly more than I expected this soon. I wasn't sure a serum at this price point would do much, but the shedding reduction alone has me keeping it in my routine. Application is straightforward — I use it at night directly on my scalp and massage it in. The texture is light and doesn't make my hair feel weighed down or greasy by morning. No irritation on my end either, which I was a little worried about. Holding off on 5 stars until I've used it longer and can speak to actual density improvement, but so far the results are promising. Will update after a couple more months. Cautiously recommended if you're dealing with excess shedding. Read more

Totally recommend this product!

I love using this product- I am attempting to fix damaged hair, and growth. I was afraid to use an oil because I didn't want my hair to look oily every day. The instructions on how and when to use the product are very clear, and it doesn't leave my hair oily at all. I have used it for about a week now and I have already seen an impressive difference! I can't wait to see the growth and damage repair in a month! I am a natural brunette and have been dying my hair a warm bright blonde for years now- I totally recommend this product! Read more

Meh. Leaves hair greasy, no real signs it’s working.

This is a decent addition to your hair growth arsenal if you’re already using products with more clinical evidence behind them (mainly minoxidil), but it isn’t likely to cause a very noticeable amount of hair growth on its own. I haven’t noticed much of a difference since I started using it, but I also use 5% minoxidil once daily. While it’s not QUITE as greasy as some reviewers claim, it will definitely leave your hair at least a BIT noticeably greasy until the next time you wash. For that reason, I basically have to skip using this serum if I’m going anywhere important or want to style my hair in anything other than a tight ponytail/bun before my next scheduled wash. I assume that your mileage may vary if you have dark-colored hair. Read more

Doesn't work. Sorry

An honest review here it absolutely does nothing. It just makes your hair greasy. I hate to say it. I've used it for 3 to 4 months. It has done nothing for hair growth. Absolutely nothing. Maybe it's placebo for other people, but it does nothing at all I think I get better results from head and shoulders than I do from this. Maybe works for some other people due to some kind of enzyme reaction but at the end of the day it really doesn't do anything and the studies are limited and the studies are funded by the company that produces the product. I do love their caffeine cream serum, but this doesn't really work. Read more

Serum + AHK + Bio Needle = Fast Improvement

It’s actually shocking how well this works. I don’t struggle with hair loss, but at 35, I could see some spots along my hairline were thinning from putting my hair up. I added a little AHK powder to the serum and used a bio needle to apply it. I’ve done this once a week for a month and that somehow has been enough for me to have a lot of new hair growth. The patches are filled in. It’s crazy. I thought I was just being preventative more than anything, but this has actually made a huge impact from just 5 applications. Read more

Great for hair

After the chemo, my hair grew back, but thin. I started to use this every night for about a year now. My hair is thicker and very healthy. I still use this and probably keep using it. Read more
