Are you taking good care of your hair and using the right products? Could your shampoo be damaging your hair? Should you brush your hair more or less? The following are a few tips to help you keep your hair healthy and shining.

★A balanced diet will help you have nice-looking hair. Try to eat more green vegetables, eggs and beans every day.

★Wash your hair every day, or every two days. Always use cool, clean water to wash the shampoo out of your hair.

★Use shampoo that is specially designed for your hair type (dry, oily, etc.).When using shampoo, be sure to massage your hair, including the roots, softly.

★Allow your hair to dry naturally whenever possible. Hair is at its weakest when it is wet, so never brush or comb your wet hair hard, and use a wide-toothed comb.

★Give your hair a good brushing before going to bed. Do this by bending over so that your head is hanging down, and brush from back to front. This will help remove the dirt from your hair.

★Strong sunlight is bad for your hair. So remember to wear a hat to protect it on hot summer days.[来源
