Hairstyle Appreciation Day is observed on April 30, 2016. It celebrates the uniqueness of all styles of hair and honors the people who make artful hairstyles possible. Hairstyling is an artful skill, on April 25 you can show your favorite hairstylist your appreciation.
A hairstyle's aesthetic considerations may be determined by many factors, such as the subject's physical attributes and desired self-image or the stylist's artistic instincts. Physical factors include natural hair type and growth patterns, face and head shape from various angles, and overall body proportions; medical considerations may also apply. Self-image may be directed toward conforming to mainstream values, identifying with distinctively groomed subgroups, or obeying religious dictates, though this is highly contextual and a "mainstream" look in one setting may be limited to a "subgroup" in another.
A hairstyle is achieved by arranging hair in a certain way, occasionally using combs, a blow-dryer, gel, or other products. The practice of styling hair is often called hairdressing, especially when done as an occupation. (With material from: Wikpedia)
