The frequency of washing your hair depends primarily on your hair type, scalp condition, and lifestyle. Generally:

• Fine or oily hair: Wash every day or every other day to prevent greasiness.
• Coarse, curly, or tightly coiled hair: Wash less frequently, about once every two weeks, to avoid dryness and damage.
• Normal hair: Washing 1-3 times per week is typically sufficient.
• People with dry scalps should wash less often, about once or twice a week, to retain moisture.
• Those with oily scalps or active lifestyles may need to wash more frequently, even daily, if preferred.

Over-washing can lead to dryness, damage, and breakage because it strips natural oils that protect hair strands. Between washes, dry shampoo or scalp care can help maintain cleanliness without shampooing daily. Adjust your washing routine based on how your hair and scalp feel, with a typical range from every other day to a couple of weeks depending on your unique hair needs.
