Hair growth follows a natural, predictable cycle composed of three distinct phases: anagen (growth), catagen (transition), and telogen (rest and shedding). At any given time, approximately 85–90% of scalp hairs are in the active growth phase. After several years, each follicle transitions out of growth, eventually shedding and beginning the cycle again.
As we age, the body’s ability to sustain robust hair growth declines. The anagen phase shortens, resulting in thinner, shorter hairs. In some individuals, follicles remain in the resting phase longer or become inactive altogether. Hormonal shifts, decreased circulation, and reduced nutrient delivery to the scalp all contribute to this change.
While age-related thinning is common, early intervention can help preserve existing hair and support healthier regrowth patterns. Recognizing subtle changes in hair density or shedding patterns is the first step in identifying whether further evaluation is warranted.
