Electrophotography Visualizes the Benefits of Liquid Crystal Technology

The process of hair coloring significantly changes the surface of hair fiber. Color-treated hair is rougher and more hydrophilic, attracting water that can leach out pigments. New shampoos and conditioners are designed to preserve hair color function by working with this surface activity of colored hair. Electrophotography now allows P&G Beauty researchers to visually capture changes in hair surface properties resulting from their newest color preservation technology - Liquid Crystals.

People all over the world see hair as important. In the west, for instance, almost all brides are prepared for their approach to the altar by the hands of an expert stylist. On that supreme day, their hair style may be the most elaborate they will ever have in their lives. At the opposite extreme, when a young girl of one of the aboriginal tribes of the Amazon jungle reaches puberty the women of the village ceremonially remove all the hairs from her head, one by one. The ritual significance and mystique of hair on these occasions are undeniable.

Our skin is the outward appearance of who or what we are, or would like to be. But it is more than just a simple cover. It is the largest organ of the body - a complex and dynamic system that is vitally important to our health, and sometimes reflects it as well.

  • A typical fine hair diameter is equal to half the thickness of a sheet of paper (56 microns)
  • If all the hairs on a single head of hair 12" long were laid end- to-end, they would stretch 26 miles
  • The total surface area of a head of hair 12" in length is equal to the floor of a 9' by 4' room (imagine spreading a dollop of hair gel over your entire bathroom floor before it dries!)

The most common areas where volume is desired are:

    R - Root lift (increases height and length of head)
    B - Bang lift (keeps hair up and off face)
    S - Side volume (hair doesn't cling to scalp)
    E - End volume (hair looks free flowing or shaped without stringiness)

Why are some of us struggling with lank, limp head-hugging hair while others seem to have full, bouncy hair all the time? The answer is physiological in nature - we inherited a genetic tendency toward fine or limp hair.

    Hair is 'dead', and we cannot permanently repair any damage that happens to it. You only get one chance with your hair!

    This is why it is so important to treat your hair properly, so as to prevent damage. One essential part of this is to adopt a good hair care routine, along the lines described below. Another is to keep chemical treatments like perming and bleaching to a minimum, as they can weaken the hair. Weak hair is easily damaged.

Most are synthetic products, designed to make the hair thicker and firmer.

    Setting lotions

    These protect the hair from heat. Liquid lotions are designed to be used on wet hair. They give extra volume to the finished style.
