How many stages or degrees of decolorization would black hair have to go through on its way toward palest yellow?

• A. 8
• B. 10
• C. 5
• D. 12

Answer: (B)

Decolorization happens in defined steps called levels. Hair color level systems count how light or dark the hair is, with black at the darkest level and palest yellow at one of the lightest levels. Each stage lifts the color by roughly one level. To go from black (the darkest level) up to palest yellow (the lightest level in this scale), you would pass through all ten levels. That means ten stages of lift in total. The other numbers would end the lift earlier in the scale and wouldn’t reach the palest yellow.
