So good!
The OUAI Scalp Serum truly worked wonders for my hair. After just one use, I noticed that my scalp felt clean and not greasy at all! Truly an amazing buy

Not a fan
Wanted to try this for a while as heard good things. It makes my hair horrible after applying. And not noticed a difference for a pricey product.

Disappointed
The first time I used this I thought WOW! Smells lovely, the following morning my roots had dried and felt clean - no need for a dry shampoo! After using it for a couple of days I started getting red patches around my hair line, like a sore/burn. I don't have sensitive skin and don't react to product. I was a bit disheartened as I genuinely liked the product to begin with but clearly my scalp doesn't. I have contacted LF to see if I can return the product due to the reaction but have been told it has to be investigated and I need to wait for a response, which a couple of weeks on I am still waiting to hear.......

Amazing
Started using this and I can honestly say this is brilliant and doesn’t leave a tingling feeling. Perfect for before or after washing hair before blow drying.

Magic in a bottle
This was my first time using any sort of hair serum, and I’m glad I’ve started with THIS one. Let me tell you - it’s amazing !!! Soo lightweight which means no greasiness after using it and does actually makes your hair a lot thicker . I massage a few drops every night into my scalp and let it work its magic, as it’s really a magic in a bottle. Definitely recommend!

Irritated my scalp
I got this because it said it helped with itchy scalps but unfortunately it just irritated my already sensitive scalp making it even more flaky than usual.
