Highlighting Performance Q&A (Weave and Slice Quadrant)

Describe a medium weave.

1/4 inch subsections weaved into 1/8 inch sections.

If you mix two batches of peroxide, one you use 20 volume liquid, the other you use 40 vol. heavy crème, mixed to toothpaste consistency, which would be lighter after 30 minutes? Why?

20 vol. liquid would be lighter because it takes more bleach to mix to toothpaste consistency and the bleach then becomes the working product.

At the conclusion of application of packets, how long will it take for the hair in the warm brown category to bleach to a yellow stage?

20-40 minutes

If a client requested a highlight, how would you explain the outcome of a weave versus a slice?

A weave will give a more patterned, streaky effect. A slice is a more blended effect.

Of the two methods, weave and slice, which requires less bleaching time and why?

Slice takes less bleaching time because there is less hair in the packet.

Name two things that cause bleach to bleed when applying foil.

1. Applying bleach too close to the scalp. 2. Applying bleach mixture too thin.

Name two things that determine how long it will take for the hair to bleach to a pale blonde stage?

1. Natural hair color 2. Strength of bleach or peroxide

If after 30 minutes of bleaching, the part of the hair you colored first is lightened to the degree you desired, what would you do?

1. Remove the foils and shampoo then proceed lightening with the rest of the head. 2. You could make the bleach formula stronger as you progress through the rest of the head.

In what way would the bleaching process be affected by adding heat?

If would lighten faster

When bleaching strands of hair utilizing 5, 10, 15, 20 vol. peroxide would the difference in the color of the strands become greater or less the longer they are bleached? Why?

It would become less because as the oxygen dissipates from the product, it is the bleach that does the lightening not the strength of the peroxide.

What is the proportion of liquid peroxide to powder bleach?

Two parts bleach go one part peroxide (2:1) or mix to toothpaste consistency.
