and another thing...the hair closet to the scalp will lighten faster than hair that is 1 1/2 + away from the scalp. here's a example:

20vol bleach will actually be 30vol at the roots and 20vol on the rest of the hair. which is why when you lighten hair that is really long, you need to do what we call a "virgin application". apply the bleach to the ends first and when you are close to your projected level, apply to the roots and they should both match by the time the bleach is finished developing.

while that bleach is sitting in the color bowl it is oxidizing and slowly becoming a 10vol. then you apply it to the roots and the heat from your scalp kicks it back up to a 20vol. have i confused anyone yet?
