Type 1 hair
Straight hair, which falls flat from root to tip without a wave or curl.
Also: straight hair
Type 1 is straight hair. It grows without a bend and tends to look shiny because light reflects off a smooth surface, and the oil from the scalp travels down it easily. Some typing charts split it into 1A, very fine and flat, through 1C, coarser with a slight bend. Straight hair shows every cutting line, so blunt cuts and sharp bobs look crisp on it, and it can be slippery for braids and updos, which may need texture added first.
