The Huffington Post recently featured an interview with Dr. Carlos K. Wesley in which he discussed the biology of the hair cycle and how this relates to men and women everyday. Although there are many external forces that may influence the rate at which the hair cycle is altered in each individual, there are fundamental patterns that hairs follow. Dr. Wesley describes these in detail.
An excerpt from the article reads: “We are born with 100,000 hair follicles on our head that are all pre-programmed to go through a certain growth cycle,” explains Wesley. “The typical cycle is about four to seven years.” But this is only true for the first couple of cycles. As your hair naturally sheds, the anagen phase becomes shorter and the hairs that grow back are a little different. “They are thinner, in smaller bundles, and their growth phase is shorter,” says Wesley. Bundles, you ask? Each follicle actually contains small bundles of hair strands. These bundles include anywhere from one to four individual strands of hair. “When we are born all of our hair is in bundles of one, but as you grow up they become two-, three-, and four-strand bundles,” says Welsey. “Your hair bundles peak at around 12 years old.” Then, sadly, as you age, bundles of four become bundles of three, bundles of three become bundles of two, and it’s all downhill from there. End result: hair appears thinner and less full.”
