The Non-Regulation Military
For the normal civilian, and of course Tom Hardy above, the high-and-tight style of the armed forces can be a little more relaxed.
What do I ask my Barber?
Ask if the barber can cut the sides and back with a short blade (from 0-1/12) up to the crown and to blend it into a scissor length that has texture, leaving and inch or two left.
How do I get it to look like this at home?
Use a puddy with a matte strong hold (see product recommendation on the next slide). This should be applied to dry hair. Moving the hair in the direction you want it to stay in or mess it up for some texture.
How often do I need to come back and cut to maintain this style?
1-3 weeks to keep the sides short.
