Hair Bleach

Cautions and Considerations

Get advice on using hair bleach safely and effectively.

If you're doing an all over blonde hair color, you'll have to apply hair bleach to the scalp, which can cause blistering and chemical burns. That's an extreme possibility, but could happen if you're not careful.

For on-scalp lightening processes, never mix bleach with a peroxide stronger than 20 Volume.

And deep in mind -- bleach just keeps on doin' it's thing until it either dries up or gets washed off.
