Leave-in conditioner is a do-it-all kind of product. After all, many can detangle, smooth, and protect against heat. Because of this, almost every haircare brand has a leave-in conditioner that they claim to be the best. So what really makes a leave-in conditioner great? The answer varies from person to person. For me, it comes down weight (I need a lightweight formula for my fine hair) and the shine it leaves me with.

I’ve found only a few leave-in conditioners that check all my boxes; and when I heard that OUAI had one available, I was excited to get my hands on it. Ahead, my honest thoughts on OUAI's best-selling Leave In Conditioner. 

About My Hair: Difficult to detangle and prone to flyaways

I love having short hair—so much so that you will rarely see me with a style that extends past my shoulders. There's a reason for this: My hair is difficult to detangle and prone to flyaways and frizz that can feel uncomfortable. My hair type prompts me to heat-style almost every day (I know it's not a great habit) and that process is usually capped with a great leave-in conditioner that smooths and protects my strands. I swapped out my go-to leave-ins for OUAI's for a week.

The Scent: Rich florals

This product's scent is so fresh and luxe, you’ll feel like you just stepped out of the hair salon after every use. The scent—dubbed North Bondi by the brand—is inspired by Sydney’s iconic Bondi Beach. Top notes include bergamot, rose de mai, violet, and more, which all contribute to the fresh, floral scent. The base notes include patchouli, sandalwood, and white musk.

This product’s scent stays with you throughout the day in a subtle, pleasant way. It's hard not to fall for, but If you are someone who likes scentless hair products this may not be the leave-in conditioner for you.

The Results: Bouncy, shiny, smooth hair

This one quickly became one of my favorite leave-in conditioners. After using it for a week, I noticed my hair look shinier and smoother. I was even complimented about how great my hair smelled!

Its lightweight feeling is the main selling point for me. It truly doesn’t feel like I have any product on, which I love because my hair has a tendency to get oily buildup from heavier products. 

The Value: Worth every penny

A $28 price tag is completely fair for a product of this quality. (Most comparable products fall around $25-30 for the same amount of product.) I just wish the brand offered a bigger size for this product because I am running through it fast. After just a week, I noticed that I’ve already used a considerable amount of product.
