Olaplex Bestsellers Set No. 3, 4 & 5

I started using Olaplex products (especially the 3,4,5 and 7) months ago. At first, I have to say quite honestly that I had the impression that this did little for my hair. In any case, no more than other fine brands. But by going ahead with it and following the advices/instructions, I now notice that my hair is really starting to improve! My hair was damaged by bleaching and paint and it is now getting healthier again. I have to say that I really use the no3 a few times a week and that I do see a big difference with using it only once a week. So the tip is to persevere and really give it a chance!

Unfortunately, it's not Olaplex for me. I have straight hair that can get oily quickly. When using Olaplex, I notice that my hair only gets greasy even faster. I once looked up how this happened online and apparently Olaplex is only suitable for very dry hair.

Can someone explain to me how to use Olaplex products correctly? I myself have thin hair with little volume, do they also have products for this in their range?
