It's ok but there's better ones out there.
I had high hopes for this leave-in conditioner, especially with all the promises of multi-level repair, hydration, and split-end mending.

The best
Hair Type Very Curly Hair
I love it so much and my hair looks amazing! My curls are so pretty and well behaved ( not fussy or messy). This was my first time purchasing Olaplax and I was a bit nervous. I'm so glad I did, it's the best product I've ever bought for my hair. I'll be buying it again!
I would buy
I have not used it yet but my hair dresser praised it, especially for my thin, colored & split end hair.
Holy grail leave in for my type 4 hair!
I took a chance and tried this leave in to help stop the breakage I was experiencing and it was the best thing I've ever done! This leave in does EXACTLY what it claims to do. After the very first use I notice a massive difference in my curly/coily hair. It had more volume, more definition with less product, and a healthy sheen. I have repurchased this product at least 3 times now and I can't wash my hair without it.
