Oily roots
Oily roots are commonly caused by an excessive production of sebum, the scalps natural oil. When choosing products you want to regulate sebum production rather than deep cleansing. Clarifying shampoos and excessive washing can stimulate the scalp and encourage increases in the production of sebum.
PRO TIP
Use a gentle shampoo and focus on the roots. Avoid getting any conditioners on your scalp and roots.
Resist the urge to wash your hair every day as over washing can worsen the issue. Instead, try a dry shampoo.
