* Greasing the scalp will help with “dry-scalp“ syndrome.

No, it won’t. “If your scalp is excessively dry, applying oil to it will not help — you may have a different problem,” Alexis says. A flaky scalp is sometimes caused by a type of yeast overgrowth on the skin, resulting in a condition known as sebhorreic dermatitis.

Since scalp is skin, it’s susceptible to the same conditions as skin on the other parts of the body — acne, folliculitis or impetigo. It’s best to see a dermatologist if your dry scalp persists.
