#4 – Sleeked Back Undercut
When Justin Timberlake could pull off this hairstyle that was popular back in the 1920s, you can pull off it too! To get this look, use a hair wax or gel to sleek your hair to the back. However, remember not to overdo the amount of the hair styling product you’re going to use for pulling of this hairstyle.
Don’t forget to give a light lift at the roots to get the most out of this hairstyle.
