His hair is also cut shorter on the sides and the top is left longer to arrange in a messy spikey-do. Here the sides are brushed forward for a fun men's hairstyle.
This gentleman has the comb over version of this style but he is certainly not experiencing thinning hair. Sideburns complete his look.
