Hair feels lovely

4 stars out of a maximum of 5

My hair feels lovely when I use this on my wet hair, the only thing I don't like is when I dry my hair it smells and it's definitely this leave in conditioner. I don't smell it when I pump it out, it's when the heat is on it it has a smell to it. I'm not 100 % sure if I'll repurchase this because I do love the ouia leave in frizz cream or the Oribe supershine moisture cream they are both brilliant leave in conditioners

Healthy Hair

5 stars out of a maximum of 5

One of my 2025 goals is to take care of my hair and this leave in mask is really helping me achieve that! Since I started using this my hair has been so much softer and shinier. Highly recommend!

Nice

3 stars out of a maximum of 5

This makes my frizzy hair feel smoother and look less frizzy. Wasn’t sticky and didn’t weigh it down. Makes my hair feel hydrated. I like that it is also a heat protectant.

Bought a full size

5 stars out of a maximum of 5

Started with a sample, but ended up loving it. I mix it with bonding oil and it leaves my hair soo soft. This is better than No. 6

Another fab product from Olaplex

4 stars out of a maximum of 5

I love Olaplex' bond building technology but rarely have time to go through the pre wash steps. This leave-in conditioner gives me the all the Olaplex benefits but none of the hassle! Plus I only need a tiny amount for my fine, flyaway hair so the tube will last ages.

Good product

4 stars out of a maximum of 5

It’s a decent product. Not as good as their smoothing balm. Leaves a white residue. Hair does feel nice afterwards.

Excellent for frizzy hair

5 stars out of a maximum of 5

I've been using Opalex leave in conditioner for 3 weeks now and I've noticed a huge improvement to my frizzy hair. The product enhances my natural curls and conditions my hair. After struggling with frizzy hair for a while from heat damage, I'm so pleased that I've found a reliable product. Will definitely be repurchasing.

Lovely formula. It doesn’t weigh my thin hair down. But a little bit goes a long way

Silky Hair

5 stars out of a maximum of 5

Leave In Moisturize and Mend Leave-In Conditioner deeply hydrates and repairs dry, damaged hair. Its lightweight formula detangles and softens without weighing hair down, leaving it silky and smooth. The pleasant scent lingers, and it provides lasting moisture, making it an essential product for maintaining healthy, manageable hair.
