Looking for some advice please - I have natural blonde hair which has gone darker with age, it’s now a dark blonde. I have had it highlighted for years, I used to have bleach ( blondor) then a high lift tint Majiblonde violet/Ash. About 4 and a half years ago I changed my hairdresser and she used Schwarzkopf bleach (not sure what one) and over the last few year has also mixed with Olaplex. From about a year and a half ago my hair has started breaking really badly, to the point where I have a layer the whole way around my head that is about nose length... the rest of my hair is below the shoulder so it looks ridiculous! I can’t carry off short hair as I have a pea head so cutting it short isn’t an option. Although I do kind of think it might be the Olaplex that has caused the damage I have read that this is impossible so it must be the bleach? I used to straighten my hair pretty much every day and have cut this back a lot over the last 4/5 months but it’s so far made no difference other than my hair looks even worse as I can’t style it at all. My hairdresser keeps saying it’s because that section of my hair gets all the elements (wind, rain etc) but I don’t buy it as 1. I don’t spend an awful lot of time outside and 2. Nothing has changed about the way I do my hair or live my life in the past 10 years other than my hairdresser, what she uses and Olaplex. I’ve looked at switching to a high lift tint and it seems there will be an issue matching up the colour and although I’d rather just stop dying it altogether the natural colour is quite dark now so roots will look terrible. Looking for some advice please! Should I switch hairdressers? Mine keeps saying to trim every 2-4 weeks and use Olaplex all the time (the salon treatment with her every 2 weeks and then the No3 plus the shampoo and conditioner) which I have been doing since summer, I’ve also hardly been straightening it, I sleep on a silk pillow and use a Mason Pearson boar bristle brush to minimise damage but it just seems to be getting worse and worse and shorter and shorter and breaking more and more I find broken bits with 4/5 splits in them! Completely lost what to do, I just want healthy hair back that’s not stupidly short at the back. Help please
