If you have hair stuck on a leather cushion cover, you can try several methods to remove it:

1. Lint roller: A lint roller can be effective in picking up hair from leather surfaces. Roll the lint roller over the cushion cover to lift the hair.

2. Vacuum cleaner: Use a vacuum cleaner with a brush attachment to gently vacuum the hair from the leather surface.

3. Damp cloth: Dampen a clean cloth with water and gently wipe the leather surface. The moisture can help loosen the hair, making it easier to remove.

4. Rubber gloves: Put on a pair of rubber gloves and dampen them slightly. Run your hand over the leather surface in a sweeping motion to collect the hair.

5. Adhesive tape: Wrap a piece of adhesive tape around your hand with the sticky side facing out. Pat the tape over the leather surface to pick up the hair.

6. Specialized products: There are also specialized leather cleaning products available that may help in removing hair from leather surfaces. Be sure to follow the instructions on the product carefully.

Remember to test any cleaning method on a small, inconspicuous area of the leather cushion cover first to ensure that it doesn't cause any damage. Additionally, always follow the manufacturer's recommendations for cleaning and maintenance of your leather furniture.
