Like another reviewer, I use Olaplex 6 & 7 as well. If you use these products, this is redundant. It's a nice product, not heavy, but if you are using the other Olaplex styling products, this one is just not going to make any difference to the outcome. I cannot use it without Olaplex 6 as my hair is just too unruly and damaged (bleaching/coloring) for this alone. It's nice but likely best suited for those with not overly processed or thick/course hair.

Hairs feel incredibly soft and hydrated. And love the smell

It smoothens hair really well from blow-dry freeze. Just make sure to not use too much! A little goes a long way.

Every time I use this product my hair is more hydrated and smooth without weighting it down. Just bought my second bottle.

I enjoyed the product and appreciate that fact that ir provides heat protection but does not contain silicones, however, found that it leaves my hair greasier/more weighted down as compared to a combination of other Olaplex products that I’ve been using (no. 6 and 7).
