* Sea salt spray or lightweight texture cream. Apply to damp hair and let it dry naturally. This will create a casual wave effect with minimal effort. * The right parting. Don’t forget to change it every couple of weeks so your hair doesn’t get used to it and loses volume. * Minimal products. This bob doesn’t need heavy styling. The lighter the texture of the products, the fresher the look will be. * Trimming every 8–10 weeks. This is enough time to keep the shape sharp without requiring frequent salon visits.
