Changes in Hair Follicles
During hair loss, both the visible hair shaft and the underlying follicle undergo changes. The hair shaft becomes thinner and more fragile due to miniaturization, reducing its size over time. Simultaneously, the hair follicle shrinks, producing shorter and finer hairs. In some instances, follicles enter a long resting phase and may completely stop hair production. The connection between the hair shaft and the follicle weakens, making hair easy to pull out. As more follicles become dormant, noticeable thinning or balding occurs.
