I'm in the process of slowly working up to platinum blonde hair. At the moment my hair is a nice light blonde so not far off, but as it's fine, I want to invest in some decent hair treatments. Ones I find in boots etc aren't really doing much. I'm looking at olaplex and for the shampoo, conditioner and 3 of their treatments, it's £97 which is making me wince a bit.
Picture to see current hair which will be getting blonder. For context, I was a medium brown shade around a year ago, so it has taken a while to get to the stage I'm at now with trips every 8-10 weeks with a good trim in between.
So back to the main question, is olaplex worth it, or are there other alternatives out there which are just as good but not as expensive?
