How long does it take for your hair to grow?
That can last from two to six years, which explains why some of us grow our hair to luscious lengths while others max out much sooner: A hair that grows for two years before stopping will be about a foot long, but one that can put in six years of growth could triple that length.
Where does the growth of hair take place?
A similar process occurs for hair. Each hair sits within a follicle that drives its growth. At the base of the follicle is the hair matrix, a group of cells that divide to produce the new cells that make hair strands longer. These cells divide very rapidly, but only when supplied with energy.

Why does hair grow?
Hair grows because matrix cells shed some of their structure as they reach the upper follicle. The shed structure combines with keratins to form hair strands that exit your skin’s surface. Researchers are still looking into what triggers our bodies to “turn on” the anagen phases.
