Here are some steps to style a long bob:

1. Start by washing your hair and towel-drying it. You can also use a heat protectant spray before styling.

2. Apply a styling agent such as mousse or soft-hold gel into your hair.

3. Blow-dry your hair using a round brush to create volume.

4. Use a flat iron to curl the ends under and give it more volume.

5. Tease at the crown for more added volume using a round bristle brush.

6. Finish off with hairspray to hold the style in place.

I hope that helps! Let me know if you have any other questions.
