Flakes and an itchy, scaly scalp are the main symptoms of dandruff. White, oily flakes typically accumulate in your hair and on your shoulders and often get worse during the fall and winter months, when the air is dry.
Pinpointing the exact cause of your itchy, flaky scalp can be difficult, but here are a few common culprits:
- irritated and oily skin, a condition also known as seborrheic dermatitis (a more severe form of dandruff)
- not shampooing enough, which causes skin cells to accumulate and create flakes and itching
- yeast called malassezia, which aggravate your scalp and cause excess skin cell growth
- different personal care products may cause contact dermatitis, which makes your scalp red and itchy
