It depends on your hair type and lifestyle. Generally, washing every 2-3 days is sufficient for most people. Over-washing can strip natural oils from your scalp, leading to dryness, while under-washing can cause buildup and scalp issues.

Choose products formulated for your hair type (dry, oily, curly, etc.) and specific concerns (dandruff, color-treated, etc.). Look for sulfate-free formulas to prevent stripping natural oils and silicones to add shine and manageability.

Frizz is often caused by dryness and humidity. Use a hydrating shampoo and conditioner, and incorporate a weekly deep conditioning treatment. Avoid rubbing your hair with a towel—instead, gently squeeze out excess water—and consider using a serum or oil to smooth frizz.
