A beautiful healthy hair is
soft, smooth, strong, shiny, fast growing and manageable.
Physical, environmental and
chemical factors can damage a healthy hair and convert it to a
dull, fragile, rough and out of control hair. Environmental
factors are sunlight, dry and hot air, and pollutants in the air.
Mechanical factors include hair bands, combs and hair brushes.
Chemical factors are bleaches, dyes, shampoos and other materials
used to style the hair.
