If you have long, wavy hair, you can try adding soft layers to give it a lived-in look. There are many benefits of soft layers for long hair, including a softer undercut, which keeps that from looking too heavy. It is also a good choice for people who have thin, straight hair. However, if you have wavy or thick locks, long hair does not suit you well. You can also go for a short bob to add volume to your style.
