Washing hair too frequently can strip the scalp of its natural oils, leading to dryness and irritation.
The frequency of hair washing depends on hair type, lifestyle, and personal preference.
People with oily hair may need to wash their hair more frequently than those with dry hair.
Those who exercise regularly or live in a humid climate may need to wash their hair more often.
Dry shampoo can be used as an alternative to washing hair, but it should not be used as a replacement for regular washing.
Overall, it is recommended to wash hair every 2-3 days for most people.
