well just to let you all know that using straighteners to remove the bonds doesnt work it just sticks the glue to your hair alot worse! Acetone doesnt really work either, it may remove the hair but chances are the glue will remain stuck in place or at least most of it. And if your like me you will even end up with small round bald patches of where your own hair has accidently been pulled out at random places about your head. No matter how much it costs I would defo go back to the hairdresser that put them in. Thats what I am doing tomorrow with big regrets at trying a DIY job!!
And just to add, it was 100% acetone I used and almost choked on, I poured 2 litres in a bucket and spent about an hour upside down with my head in.
