Is one single hair is called a strand or a bundle of 40-50 hair or say bunch of ringlets of hair is called strands?
okay but dictionary meaning of strand says a wisp or tress of hair or grass.
Human hair grows everywhere on the body except for the soles of the feet, the lips, the palms of the hands, and the eyelids, apart from eyelashes. Like skin, hair is a stratified squamous, keratinized epithelium made of multi-layered, flat cells with overlying keratin (a protein), whose rope-like filaments provide structure and strength to the hair shaft.
Hair follows a specific growth cycle with three distinct and concurrent phases: anagen, catagen, and telogen phases. Each phase has specific characteristics that determine the length of the hair. All three phases occur simultaneously; one strand of hair may be in the anagen phase, while another is in the telogen phase.
The body has different types of hair, including vellus hair and androgenic hair, each with its own type of cellular construction. The different construction gives the hair unique characteristics, serving specific purposes, mainly warmth and protection.
From the explanation in the last sentence of the second para, it becomes clear thet strand’ refers to only one piece of hair.
