Traditionally, men have used what is referred to as a "Club" brush--a wide-based brush with densely packed bristles and a shorter length handle. This brush is best used for smoothing hair, not texturing or detangling, as most women's brushes are used for. Since men usually have closely cropped hair, they need o use a brush closer to the scalp to effectively smooth their hair.
Also, the short handled brush was designed to allow a man's hand to closely grip the brush and thus better control its smothing action. In addition, the shorter handle style is usually a wider or thicker handle, which fits a man's larger hand more comfortably and provides a stronger brush that won't break as easy.http://www.ehow.com/about_5091254_history-hair-brushes.html
