If you suffer from an itchy, flaky scalp, washing your hair too little can make the problem worse. Use a sulfate-free shampoo and try washing your hair at least every other day.
Flakes that are left in place also provide a haven to yeasts and bacteria, trapping sebum, hair products, and dust or dirt on your scalp. This is the perfect recipe for a full-blown breakout of dermatitis.
The solution is simple. Just wash the flakes away and rinse thoroughly to keep your scalp happy and itch-free.
