1. Hair spray is generally a type of varnish and as such will leave a residue.

   If you clean the walls prior to repainting, you should not have a problem painted over the residue. If the residue is brown and not just slightly visible, I would recommend an acrylic stain sealer/primer for the affected wall.

2. Before repainting the bathroom walls to cover up hair spray marks, it is essential to properly prepare the surface to ensure a smooth and long-lasting finish. Follow these steps for effective preparation:

   1. **Clean the Walls**: Use a mixture of warm water and mild soap to clean the walls thoroughly. This will help remove any residual hair spray, dirt, and grime that may prevent the new paint from adhering properly.

   2. **Degrease the Surface**: Hair spray can leave behind a greasy residue that can interfere with paint adhesion. Use a degreasing cleaner or a solution of water and vinegar to remove any oily residue from the walls.

   3. **Sand the Walls**: Lightly sand the walls with fine-grit sandpaper to smooth out any rough patches or imperfections. This will also help roughen up the surface slightly, providing better adhesion for the new paint.

   4. **Fill in any Holes or Cracks**: Inspect the walls for any holes, cracks, or imperfections. Fill them in with spackling compound or a suitable filler, and then sand the area smooth once it has dried.

   5. **Prime the Walls**: To ensure proper adhesion and uniformity of the new paint, apply a coat of primer to the walls. Choose a primer specifically designed for use in high-moisture areas like a bathroom.

   6. **Choose the Right Paint**: Select a high-quality paint that is designed for use in bathrooms or high-moisture environments. Consider using a semi-gloss or satin finish, as these are more resistant to moisture and easier to clean.

   By following these steps and taking the time to properly prepare the walls before repainting, you can ensure a professional-looking finish that will last for years to come.
