Using baby powder as a dry shampoo may cause dryness due to its absorbent nature in some individuals, mainly if used more frequently or in large amounts. Use a shampoo specifically formulated for dry or damaged hair instead if you have dry or damaged hair. These types of dry shampoos may contain ingredients that help to moisturize and nourish the hair rather than absorb oil and moisture. If you choose to use baby powder as a dry shampoo, follow the safety instructions carefully and ensure the quantity you use is safe.
