The colour of your hair depends on how much of each type of melanin, or pigment, it contains. All hair colours, from black to blond and everything in between, result from the blending of just two types of melanin: eumelanin (dark) and phaeomelanin (light). Each hair grows out of an individual follicle, or tiny tube beneath the skin's surface. Pigment cells in the follicle inject melanin into the hair shaft as the hair develops and grows longer. In later years, the follicle slows its production of melanin. Hairs with less melanin appear grey in colour. If melanin production shuts down altogether, then the new hairs, lacking any melanin, will be white.Which organisational structure does this text primarily use?

Solution
The text primarily uses a cause and effect organizational structure. It explains the cause (the amount and type of melanin produced by the follicle) and the effect (the resulting color of the hair). It also explains the cause (the slowing down of melanin production in later years) and the effect (the greying or whitening of the hair).
