The Ordinary Multi-Peptide Serum for Hair Density - Size: 2 oz/ 60 mL

Don't know how it "works" yet as far as hair density, but it feels very nice. No smell, light texture, not greasy and does not weigh down hair any. My hair is fine AND thin, and it hasn't been a bother at all. Nice to use with no need to rinse out.

I love all of my Ordinary products. They are all fragrance free and do exactly what they claim!

It's quite good. I started using it. I hopefully feel it's going to give me a result.

I'm using it for quite awhile and it's worked on my scalp for hairfall. a little greasy but useful

It's good and keeps my hair hydrated.

I didn't use it long because using semi permanent hair color, it made color disappear faster. Otherwise light scent, easy to use.

I do not have any noticeable improvement to my hair density.

i have bought this serum so many times from places like sephora or ultra. never had a problem and it worked great. something is wrong with this product. the liquid is light yellow when its to be clear and my hair is left hard like i put gel in it. when i brush it out my hair feels so sticky and unmanageable to the point I have to wash and shampoo it twice to get it off. something isn't right.

Already opened, don't know if it was used or tampered with. Don't even know how long it's good for. It also smells like nothing so I dont know if it's just water or not.
