Not sure
I do not see any difference after using this product. You cannot use a hair conditioner before using this product causing my hair looks terrible when dry.

My go to
As an Olaplex girl for many years I was super excited to try this. This is so convenient that you put it on post washing your hair and dont have to wash out. I followed the instructions and used for 6 consecutive washes and then dropped to maintence mode which is once every 3-4 washes. It repaired so much damage to my bleached hair, just be careful not to use too much or it will weight your hair down

So much fun
Have given these as little gifts and people love them They dont last long on places like fingers and wrists but any other body areas you will get about two days

Expensive but effective
This definitely is an expensive product, but it does make a visible difference in my hair health - I use it only once a week (but wash my hair 3 times per week) and it still works.
