Smells amazing. I mostly apply after washing my hair. I believe it also helps with hair falling too. Can see some baby hair. Just need some time to observe

Great to use in between washes, and has delayed dandruff a little. Still in the process of using it.

This brand is the absolute bees knees. I was super nervous at first about how this product would make my hair look greasy (you can apply it in the morning and then wash your hair at night). I was worried it would make my scalp itchy. It did none of that. It smells amazing, and I am super excited to see how it works after several weeks. I have several product from this brand, I absolutely love OUAI! 10/10

I’ve been losing hair due to stress, and I decided to splurge on a hair serum. The first two weeks I didn’t think it would work, but after almost two months of use, my hair significantly reduced shedding, I’m starting to have very noticeable hair growth and my scalp gets oily far less quickly than it used to! Would buy again, but I hope they make refillable packaging because it comes in a glass bottle that’s super easy to reuse but they just don’t consider that….
