Hair follicles do not simply serve as reservoirs for new hair to come out of, but rather they determine the amount of growth each strand receives. Essentially, hair follicular cells are the key organs responsible for the various thickness and length of each hair strand. As the follicle cells divide, they manufacture keratin to make the strands stronger and longer. Since shampoo, gels, mousse, and other styling products merely work the cells by opening and closing, it is very important to use products that help clarify the scalp and increase the flow of nutrients-particularly nutrients that strengthen and lengthen the roots so that more hairs will grow.
As stated earlier, the hair is made up of billions of tiny hair-producing follicle-causing cells called keratinocytes. These follicular cells also divide, but because of the stresses in our lives such as pollution, stress, and many other factors, their ability to function properly decreases.

However, if you want to know how to do hair follicles work, you should look for ways in which you can improve your overall health as well as how you can address issues like thinning or dullness of the hair.
