I received a full size product of OGX Pro Growth + Peptide Scalp Serum 0.33 fl oz from Pinchme to try for my honest opinion and I must say I like that the product doesn't have a scent to it, that it doesn't make my hair feel greasy or weighted down. It will take a little time to see if it helps with hair growth and hair health. I have thinning grey hair so I'm hoping the OGX Pro Growth + Peptide Scalp Serum will help me out.

I love any product that can help keep my hair in my head at this point in my life. I’m in my 40s and I’m losing a lot of hair. I hope this product will continue to stop some of my hair loss.

I received a free sample of OGX Pro Growth + Peptide Scalp Serum in exchange for an honest review. After using the product for a couple of weeks I would definitely recommend it to others. My hair appears to be healthier, stronger and more manageable. It had less breakage and just feels more healthy. A little goes a long way with this product as well.

This serum was super convenient to apply, I loved that you don’t have to get your fingers greasy in order to apply it. It made my hair nice and shiny and helped it grow strong and healthy!

I received this product for free in exchange for an honest review. I honestly can’t tell if it has done anything? I typically use it at night before a hair wash day as it leaves my hair a bit greasy. No smell. Easy to use. But has it done anything? I’m not sure.

I really like the OGX Pro Growth + Peptide Scalp Serum. It feels lightweight on my scalp and doesn’t leave my hair feeling greasy or heavy. It’s easy to apply and absorbs nicely. I’ve been using it as part of my hair care routine to help support healthier, stronger-looking hair. I also like that the bottle is small and convenient to use. So far, I’m enjoying it and look forward to seeing the results with continued use.

After using this for a while I didn’t notice any dramatic growth change. It did t seem to make my hair grow any faster or thicker than it normally grew. I liked the smell and the consiypf the oil though.

I got OGX Pro Growth + Peptide Scalp Serum 0.33 fl oz as a free gift from pinchme. Feels ok in my hair, no side effects, but also haven't noticed any significant growth since using. I guess needs a long time of consistent use before progress is shown?

I didn't have much hope so I never bought if cuz I was afraid it wouldn't help but after getting a free sample from pinch me to try it i ended up buying another one because I actually liked how it was working on my thinning hair

I'm grateful for this opportunity and such a good quality product. I can not wait to share this product with all my family and friends.

I received this product as a free sample. I used the product every day on my scalp and hairline and honestly didn't really notice any difference or changes. I did however really love the applicator - it was so easy and convenient to use and not messy like so many similar products. Overall I wouldn't personally recommend the serum, but it might be effective on some people.

I recieved a free sample of the OGX Pro Growth + Peptide Scalp Serum to try out. I like it so far but unsure how much it has actually contributed to growing my hair.

I am very sensitive on my scalp. I haven't tried it fully, just a small test. I have eczema, on my scalp. I intend on trying it more in depth on my vacation days from work.
