It happens every day to millions of women around the world – troubles with bad hair. Scientists working for Proctor & Gamble have found that coloring your hair can increase the chance of having bad hair days.
Hair is typically coated with a protective layer of natural oil that is uncharged and repels water. Chemicals used in colors strip away this layer and as a result, hair becomes negatively charged and attracts water. This all means that hair becomes difficult to manage!
Scientists, using high-powered microscopes, discovered that just one or two applications of hair dye
can cause hair to become highly charged. When this happens, hair sticks together when wet. The way the hair behaves is completely changed.
When you color your hair, this protective layer is almost completely removed. Hair cannot recreate this layer. Only new hair can have it.
Chemicals that remove the oily layer are peroxide and ammonia. They can be found in most hair dye products.
Scientists also discovered that traditional shampoos and conditioners cannot repair the damage. This is because the chemicals found in these products, for example silicon, could not adhere to the negatively charged hair. It means that using this traditional products is waste of time and money.
Scientists at P&G, however, have a solution to the problem. They have created liquid crystals that can adhere to the negatively charged hair. They can be found in a new range of Pantene shampoos and conditioners.
