      sterilization is killing of pathogenic organisms and disinfection has a bacteriostatic funtion i.e. preventing their growth

      Disinfection: The destruction or removal of vegetative
      pathogens but not bacterial endospores. Usually used
      only on inanimate objects.

      Sterilization: The complete removal or destruction of
      all viable microorganisms. Used on inanimate objects.

    Everyone who is into style depends on a great
    stylist to look good and help with hair issues and problems.
    Before you go for them, try products at Keranique for hair
    care. Generally, these products are more expensive than their watered-down counterparts,
    but you can find a few affordable pure silicone hair products (see
    below).
