1. Depending on the desired degree of lightening, mix with bondbar Creme Developers 10 vol., 20 vol., 30 vol., or 40 vol. in a ratio of 1:2 (1 part lightener to 2 parts developer) in a non-metallic bowl. (When applying directly to the scalp, do not exceed 20 vol. developer.)
2. Apply to dry, unwashed hair. DO NOT USE HEAT. Do a strand test prior to application.
3. Use mixture immediately and discard any unused mixture.

Patch Test:
Prior to application, a preliminary patch test should be conducted. The following patch test must be made 48 hours prior to each application.

1. With soap and water, wash an area the size of a circle 1 inch diameter (2.54 cm) in the bend of the elbow or behind either ear, touching the hairline. Pat area dry with absorbent cotton.
2. Apply a small amount of color directly from tube to test area, using an absorbent cotton-tipped applicator.
3. Let test spot dry. Do not wash, cover, or disturb.
4. Leave on for 48 hours. Examine at 24 and 48 hours. If no reaction has occurred, you are ready to color. Do not use hair color if any of these danger signs appear: burning, itching, swelling, eruption, or irritation. If these signs appear in or around the test area, it indicates that the patron is hypersensitive and color must not be applied.
