I had tried this years ago (around 4 years ago) and at the time I hadn't been that impressed, it seemed to make my hair feel like straw, perhaps because my hair was glossy and shiny and healthy, or the formula was more protein heavy, I am not sure.
Since then I have had some bleached highlights and some hairdressers haven't been brilliant. My current one is wonderful, but took time to find.
My hair however has got very dry and puffy.
So I tried Olapex again recently. I tried an in salon Olapex treatment, and took step 3 home. I was impressed. This 3 step process added a swish and a soft substance to my hair I forgot could exist. I have used the step 3 once a week at home and continues to bring back the soft and shine from the in salon treatment. I think that the steps 1 and 2 need to be done for step 3 to work well (perhaps I'd not done that the first time I had tried Olapex).
For me, I think that this will become a staple that will make my hair glossy in time. I only wish wish wish I had used it for the last 4 years at every in salon treatment. I wish!!!!! If I had known then what I know now. You can't buy new hair, invest in it, it makes a world of difference to your appearance.
