Hair Cycle Dysfunction = Hair Loss
The underlying causes of hair loss are varied and complex. However, the process of hair loss and thinning sometimes referred to as follicular miniaturization, is the same in both men and women. Hair naturally goes through cycles of growth, rest and release/fall, With the growth cycle normally lasting 3 – 8 years. Things such as hormones, genetics, changes in diet, stress and age can upset the hair cycle process and this leads to hair cycle shortening. Specifically, the growth phase, known as anagen, becomes very short, the follicles undergo a process of miniaturization where they shrink and hairs become thinner and less substantial as they transition from terminal to vellus hair. After an extended period of hair cycle dysfunction, the arrector pilli muscle detaches, the reservoirs of stem cells are lost and hair follicles may die.
