I wish I'd found this years ago because it is the best shampoo and conditioner I've ever used

This is the BEST hair care system I have ever used.....it is expensive!

My hair feels healthy and strong using this.

Few customers complained about receiving an empty container...mine came completely sealed, there’s no way it could leak...been using this shampoo, conditioner and hair mask for over 2 years, I’m very happy with it as it actually helped my hair regenerate after years of bleaching it...also, you don’t need to use a lot of it, which makes it last just as long as if not even longer than a regular 300ml bottle

My hair has been falling out since using this product, unfortunately.

Olaplex 4 shampoo is by far the best product I have used for my hair

Olaplex is simply the best product line I have ever used, no question about it!

This is the BEST shampoo I have ever used

After using this product and the conditioner too for only about 3 or 4 times, I can see a major improvement in the softness, strength and manageability of my hair

This is the best product I have ever used that did exactly what it is supposed to and more.

It smells great, leaves my hair very soft and clean-feeling, as if it has got rid of all the bad shampoos I have used in the past.

Since first use makes my hair harder to manage, opposite of softening and moisturizing on hair and not the greatest smell either.

This has been the best shampoo I've used so far
