Olaplex No.0
I use this once a week with No.3 treatment, and together with the shampoo and conditioner from Olaplex, I am really pleased with the health of my hair. It was brittle and so short but using these products for 12-15 months I have seen improvements. My hair is healthier and growing!

It's okay
I love the olaplex range. I used this before the number 3. I didn't really feel like it added much to the health or feel of my hair. I feel like the number 3 is just as amazing on its on. Also with the consistency being basically water you do use a lot of product

Could this be the secret to beautiful hair?
I’ve used olaplex on and off for years- usually when I want to grow my hair. I’ve never had this product before, but have bought it as a product to use alone- not with the bonding treatment. I tried it today as a 10min mask pre wash and it’s lovely! My hair looks conditioned, tame and loved!

Hair feels stronger
My hair feels stronger and has less breakage whilst washing. The application is a bit annoying as it squirts everywhere there could be and improvement made on the applicator.

Makes hair stronger
I do not need to use too much of this as I haven't bleached my hair in years, however my hair does still need a little extra help every now and then. By spraying this over my hair and leaving it for 10 minutes before I wash it, my hair feels silky, shinier and it becomes a lot more manageable. I also do not need to wash my hair as much after using this product as my hair does not become oily afterwards. I only use this at least once every 2 weeks and my hair loves it!

Olaplex 0
I use this before olaplex 3 once a week to maintain health of my hair. I’m uncertain if it’s necessary to get the best out the olaplex 3 but I use it anyway…

Would recommend!
This is the type of product that you don't necessarily see results with straight away but is working on your hair from behind the scenes! I've used this for a few months now and have noticed a difference on the damage of my hair. I use usually before washing my hair
