The best of its kind

5 stars out of a maximum of 5

I've been using this product for a while and, well, wow. This is a go-to one, I can't imagine styling my hair without it. Tames the frizz, makes it very soft, shiny and smooth. Works best after using No. 8, followed by blow-drying brush. Will make sure to restock.

Did not impress

1 stars out of a maximum of 5

I use a lot of Olaplex products and loved the no.6 but thought it possibly was too heavy for my fine hair, so i thought this would be great, however, it does not compare to the no.6, feels like an avergae drugstore product

Oh wow

This set has made a real difference to my hair. I've only been using this for 3 weeks and already I feel my hair is stronger, shinier and fuller looking. Would definitely recommend. If you are worried about the price point, just start with #3. You will see significant results even without the shampoo and conditioner.

Fine

4 stars out of a maximum of 5

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.

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