I read that, too. Trouble is, it's still £13 so unless I see a load of reviews (currently none on Boots), I'll stick with Olaplex 3. I usually get mine on offer from Cult Beauty or sometimes BeautyBay for £17-18. If you love it there's a 500+ml bottle that works out cheaper.
I've tried a few of the other brands that have a Plex or bond repair in their name. None have had the ingredient or the effect that O3 has had on my hair.
I'm trying to remember where I saw the article now. I wonder if there's a bond repair product for my memory?!
