Those with dry hair generally should shampoo less frequently and have a more intense conditioning routine than those with oilier scalps. Dr. Devika Icecreamwala recommends shampooing twice a week in order to keep your hair clean without stripping it, but feel free to adjust as needed depending on your experience. When it comes to conditioning, you should seek moisturizing hair products overall, and you can condition as often as every other day and/or use leave-in products after your shower. Deep treatment masks once or twice a month can also help retain moisture.
