If you color your hair, try to minimize doing it to around once every two months. Hair dying can dry out and damage your hair with harsh chemicals. If you limit it to every two months, your hair will have time to recover from the damage that you had done previously.
You must drink lots of water to have the healthiest hair possible. Water not only hydrates your body, it also hydrates your hair. Drinking plenty of water makes sure that your hair is hydrated, which leads to less frizzy days! As a goal, always try to drink about eight glasses of water every day.
