Human: I've noticed that my skin is a bit dry. What causes this? Assistant: 
Dryness in the skin can be caused by a number of factors, including dehydration, harsh cleansers, lack of hydration from the air, and certain medications. To help prevent dryness, make sure to drink plenty of water, use gentle, non-abrasive cleansers, moisturize regularly, and avoid using too many harsh soaps or detergents.
