Hair is a Lifestyle, and must be represented to the fullest.
Your hair is the starting point of your entire look. Have you ever changed outfits numerous times because something was off, about your look? More then likely, it was simply the way your hair was styled.
Your apparel can be on point, your accessories, as well and your shoes, can be A1, but without perfectly coiffed hair, your look will not "bring it"!
Pick your hair and hairstyle(s) wisely! It plays a tremendous part of your complete look.
