  Alan Kossof, general manager and salon director of the Teddie Kossof Salon Spa in Northfield, Illinois, says that the two main types of hair glaze are clear and color glaze. Both are treatments applied to dull, dry hair by a trained color professional.
  
  

Scientific Side of Glazing

  A clear glaze, applied to color-treated hair, fills holes in the hair cuticle--much like filling potholes in a road. The result is a barrier that locks in color and shine. The benefit is about two weeks more of color. Kossof says even the highest quality hair color and use of anti-fading, sulfate-free shampoo fades in about three to four weeks.
  
  

Auburn/Red Hair

• People with auburn or reddish colored hair lose color faster than other colors. Color molecules don't bond as well, Kassof says. People with this hair color benefit from having their hair cuticle flooded with glaze, providing more life, bounce and shine as well as longer color.
  
  

Color Glaze

• People who want to provide a cascading color hue that shines in the sunlight and adds sleekness and sheen to their hair should ask for a color glaze. This treatment lasts one to two weeks but can still look good for up to four weeks with limited shampooing and heat treatments.
  
  

Safe

• Because glazing does not sit on the hair's roots, there is no danger of it entering the blood stream.
