A hairstyle's aesthetic considerations may be determined by many factors, such as the subject's physical attributes and desired self-image and/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 (military-style crew cuts or current "fad" hairstyles such as the Dido flip), identifying with distinctively groomed subgroups (e.g., punk hair), or obeying religious dictates (e.g., Orthodox Jewish have payot, Rastafari have Dreadlocks, North India jatas, or the Sikh practice of Kesh), though this is highly contextual such that "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.
Hairstyling may also include adding accessories (such as headbands or barrettes) to the hair to hold it in place, enhance its ornamental appearance, or partially or fully conceal it with coverings such as a kippa, hijab, tam or turban.
