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

The product is good as a volumizing agent. All the hairs are separated from each other. No-greasy formulation. Observed no other positive effect.

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
