puffs" (a cross between an Afro and pigtails) and a variant in which the Afro is treated with a blow dryer to become a flowing mane. The "hi-top fade" was common among African-American men and boys in the 1980s and has since been replaced in popularity by the 360 waves and the Caesar haircut. Other styles include plaits or braids, the two-strand twist, and basic twists, all of which can form into manicured dreadlocks if the hair is allowed to knit together in the style-pattern. Basic twists include finger-coils and comb-coil twists. Dreadlocks, also called "dreads", "locks" or "locs", can also be formed by allowing the hairs to weave together on their own from an Afro. Another option is the trademarked "Sisterlocks" method, which produces what could be called very neat micro-dreadlocks. As well as faux locs, a type of synthetic dreadlock which is obtained using extensions. Manicure locks—alternatively called salon locks or fashion locks—have numerous styling options that include strategic parting, sectioning and patterning of the dreads. Popular dreadlocked styles include cornrows, the braid-out style or "lock crinkles", the basket weave and pipe-cleaner curls. Others include a variety of dreaded mohawks or lock-hawks, a variety of braided buns, and combinations of basic style elements. Natural hair can also be styled into "Bantu knots", which involves sectioning the hair with square or triangular parts and fastening it into tight buns or knots on the head. Bantu knots can be made from either loose natural hair or dreadlocks. When braided flat against the scalp, natural hair can be worn as basic cornrows or form a countless variety of artistic patterns.

A majority of Black hairstyles involve parting the natural hair into individual sections before styling. Research shows that excessive braiding, tight cornrows, relaxing, and vigorous dry-combing of kinky hair can be harmful to the hair and scalp.
