I loved using this product because I have a really dry scalp naturally. While I didn't necessarily see a huge impact on hair growth, I could tell a major difference on the condition of my scalp and that was worth it.

While I didn't see any amazing results, I did like the applicator compared to other scalp serums I've used

I tried this product over the course of a couple of months and I got so frustrated with the dispensing of the serum that it dominated any thoughts I had of the actual product. The container LOOKS beautiful, but when clicking to dispense the contents, I had to click over and over and over to remove the air bubbles and still was unsure if the drops landed. I think I'd prefer something more manual like a dropper so I could ensure the product was placed on my scalp. As for hair growth or shine, I could not notice a difference.

I tried the serum hoping for hair growth. It does feel nice and cool going on. I would need much more time to see if it helps with hair growth.

It's a hair serum, light weight and non-greasy. It's easy to use and does not leak. It will fit in any purse for travel. I could not see the results in two weeks, but I would continue to apply it and see if it works.

This product made my scalp feel great. I am not sure about the hair growth. I take vitamins for my hair and nails so I am not sure if I should see a difference. I bought it so I can continue to use it to see if it helps hair growth.

I received this product in exchange for my honest review. The OGX Pro Growth + Petptide Serum mist is easy to apply and focus on the hairline areas intended. The product absorbs pretty well and did not leave a greasy or heavy residue.

Ever since I had my two girls, I’ve struggled with getting my hair back to normal. This product has been a godsend! I have noticed a good amount of regrowth. I like that you can still use the product between wash days.

I received my OGX from PinchMe. I used it on my scalp. It didn't leave any residue. It has helped my head hasn't had any itchiness or flakiness. It smells good. I recommend it.

Received this product amongst others from the OGC brand as a sample from PINCHME and i am impressed. Love that this scalp one is so light and not oily. The bottle is sort of also an applicator so is easy to apply to your scalp. Leaves my scalp feeling light

I have been using the OGX Pro Growth + Peptide Scalp Serum and I am so impressed! I have noticed my hair thinning with age so I was very excited to try this serum. I used it daily for months and really see a difference! I have new growth, less shedding and my hair looks and feels thicker. I will certainly continue to buy this product! OGX products are all effective at a great price point!
