The Process

• When hair is bleached, the bleaching agent in the formula is mixed with a peroxide solution known as a developer that opens the cuticle so the bleach can enter the hair cortex. The developer then eats away at the natural hair shade located within the hair molecules. When hair is tinted with another colorant, the color replaces what is stripped away; however, during the bleaching process there is no replacement of colorant that occurs which is why it weakens the hair and often leaves it dry, damaged and coarse.
  
  

Shampoo Less, Condition More

• To recondition your hair into a healthier state for your next bleaching experience, cut down on the number of times you shampoo your hair, going two to three days in between washings. This enables your hair to acquire more natural scalp oils to help condition your damaged strands. Avoid shampoo formulas for "oily" hair and buy those rich in emollients for dry and damaged hair. Some formulas are specifically designed for chemically processed hair and may help restore moisture and minimize damage. Cut down on the amount of shampoo you use to one-third the normal amount and wash hair in tepid water, rinsing thoroughly.
  
  Conditioning is crucial to your dry hair, and there are many deep-conditioning hair treatments available on the market in addition to leave-in conditioners. When rinsing hair after conditioning, always use icy cold water to help seal the moisture into the hair follicles. Avoid heat-styling devices such as blow dryers and curling irons, which further damage hair and can cause splitting and breakage.
  
  

Doing the Deed

• If and when you do decide to have your hair bleached, it is recommended you go to a professional if you have any signs of previous damage. Professional hairdressers can gauge what type of colorant to put on your hair and for how long to minimize any further damage. They may also apply conditioning treatments that will aid in repairing your hair after your coloring. Many hair salons use techniques that are not available when at home, such as moist heat lamps, color processors and infra-red heat devices that can speed up the coloring process and help you to avoid additional damage to the hair.
  
  If your natural hair color is dark, it is always safer to go slowly when lightening your hair rather than in one fell swoop; this will minimize damage caused by over-processing and cause a less drastic shock to your hair follicles. Try coloring every three months just a few shades lighter to help you to arrive safely and slowly towards your hair color goal.
