Frizz
Strands that rise out of a smooth shape or curl group, giving a fuzzy outline.
Frizz happens when individual hairs stand away from their neighbours instead of lying smooth or joining a curl. Damp air is a common cause, because dry hair takes up moisture from the air and swells unevenly. Rough towelling, brushing curly hair when dry and raised cuticles add to it. Curly-hair routines reduce frizz by scrunching, drying with a diffuser or air drying and touching the hair less. Some styles, like a stretched afro, embrace a soft outline.
