Directions

APPLICATION 

WET HAIR

- Spray about 6 to 8 inches away from eyeline down. Using a wide tooth comb, from the eyeline begin brushing hair.

- The combing process will allow the right amount of product to reach the roots without having to directly apply there.

DRY HAIR

- Thicker, coarser or curlier hair can apply on dry hair for a much-needed dose of hydration, shine, frizz and flyaway control.

Rated 5 out of 5 by from Summery scent I regularly use the original OUAI leave-in conditioner and decided to the try St Barts version. It has a delicious, tropical pina colada fragrance and feels like a light, refreshing mist. It's perfectly hydrating without weighing the hair down and it helps control the frizz for my curls.

Rated 5 out of 5 by from Heavenly Scent and Thicker Fuller Hair New haircare staple! I absolutely love this product, I’ve been using it for a couple weeks now and notice a difference in my hair, it feels much thicker and smoother and smells heavenly. I work selling haircare products but unfortunately we don’t sell this one but I can hands down say this is my favourite! I’ve noticed my hair actually looks blonder and shiner since I’ve used it and overall feels healthier, I love mixing this and K18 as a leave-in treatment together. I would highly recommend for girls with fine bleached hair! It’s a game changer!

Rated 5 out of 5 by from Soft, shiny, frizz free hair I'm nearly finished with the first bottle I purchased and need the product to come back in stock because it is so good. It leaves my hair lovely and soft, gives it a lovely shine, and controls frizz. Further, it smells incredible. Deffo a repurchase for me
