This is what i understand...... the alpha keratin in hair are linked together by disulphide bonds. hydrogen peroxide, which is used to bleach hair, oxidises cysteine in the keratin, making more disulphide bridge as it removes hydrogen atoms connected to the sulphur. This leaves hair brittle. Perming lotions have opposite effect - they break disulphide bonds. So from my point of view , both bleaching and perming at the same time don't seem to cause a problem since both crosses out each other. But my answer, it seems , is not correct . Why?
Re: Why is it not advisable to have hair bleached and permed at the same time?
