Of course, hair bleaching is quite a dangerous chemical procedure (make sure to use a hair mask after bleach). Dust-free bleach powder should become your ultimate choice if you decided to repeat the bleaching procedure. However, we don’t recommend performing it twice if there are any other options.
In case if you just NEED to perform hair bleaching for the second time, we highly recommend using the Bond Angel kit for bleaching which is the best product for saving your hair even if you bleached it twice. Just add 2 ml of Bond Maker for every 10 g of bleaching powder used. As you can see, everything is very simple! In the kit, you will get not just Bond Maker but a 2 x Bond Reconstructor which is a post-chemical rebuilder making your hair lively again!
