If you have a dry, flaky scalp, a dandruff shampoo used correctly can help stem those flakes.

The American Academy of Dermatology advises:

• There are different types of dandruff shampoos with different active ingredients. Make sure you carefully read and follow the label’s instructions.
• People of Asian or Caucasian heritage should limit use of dandruff shampoo to twice weekly.
• People of African-American ethnicity should limit use of dandruff shampoo to once weekly.
• People with white, blond or gray hair should be careful when using dandruff shampoo that contains coal tar, which can affect hair’s color.
• Protect your scalp from the sun if you use tar shampoo, which may make your skin more sensitive to sunlight.
