You can try many techniques of dry hair treatment but the effectiveness of one would depend on your hair and scalp type. You hair becomes dry when its moisture and oil content is reduced. One of the functions of the skin on your scalp is to reproduce these oils naturally. But if that does not happen due to any reason, you need to take appropriate treatment.
Dry hair can be caused by mechanical damage such as throw blow dryer, environmental damage such as exposure to sun, chemical damage due to artificial colours and bleaches, and natural dryness.
