Final answer:
Shonda should avoid clay/mud masks for hydrating her client's skin, as they can be drying. Instead, she should opt for sheet masks, cream masks, or paraffin masks that are designed to provide moisture to the skin.
Step-by-step explanation:
Shonda needs to choose a mask for her client to hydrate her skin. The type of mask Shonda should avoid for hydration purposes is the clay/mud mask. These types of masks are excellent for absorbing excess oil and are best suited for oily or acne-prone skin. They can be drying if used on skin that requires hydration. On the other hand, sheet masks, cream masks, and paraffin masks are ideal options to hydrate the skin. Sheet masks are soaked in serum to deliver intense hydration, cream masks usually contain moisturizing ingredients such as hyaluronic acid, and paraffin masks form a barrier on the skin's surface, which helps to seal in moisture.
