All time go-to product

My go to hair product! I’ve been using Olaplex products fir a while now and this my favorite by far. Not only does it nourish and hydrates your hair but if used prior to blow drying, it acts as a nice protective coating. Highly recommend it

Left my fine hair frizzy

Purchased this because it was described as a lighter leave-in conditioner. I'm pleased to report this is true, but almost to a fault. I doubled up and still found it to be so light that it actually leaves my hair frizzier than before. I strayed (purely out of curiosity) from my regular Ouidad Climate Control Leave-In Conditioner spray and I think I will go back to it after trying this. This conditioner did have a very light and pleasant scent, and if you're looking for a very light product, this would fit the bill but for my fine curly hair, it just didn't deliver the results I need.

Big fan!

I have used almost all of the Olaplex products at this point and have been very happy. I have porus, curly hair that can't get enough moisture, so having a leave in conditioner is great. I've used no. 6 and 9 and love them both. This one is a bit l8ghter than 6 and still a cream. Great for days when I need a lighter leave in.

Just What My Hair Needed

I was concerned about using this product on my hair because I have fine thin hair. I was so sure that this product was meant for others that don’t have my hair type, but to get an answer I decided to email Olaplex and ask them. My hair has a tendency to have fly-away ends that I wanted to have tamed and apparently this product , according to Olaplex, is just perfect for my hair! I have been so delighted with this product that I will probably get a subscription so I never have to worry about not having enough. It goes on with just one pump from the applicator, and not only holds down those fly away ends, but also conditions and protects my hair from heat damage. To add another positive point it does not weigh your hair down, and actually makes your hair healthier in appearance, too. This conditioner along with other products from Olaplex have really made a difference for my hair-
