Science of the hair

The hair growth cycle is a complex process that significantly affects how our hair appears and behaves. Understanding the four phases—anagen (growth), catagen (transition), telogen (resting), and exogen (shedding)—is essential for effective hair care. The anagen phase is the stage where hair actively grows, lasting for years, and its duration can vary based on genetics and health. The catagen phase, though short, is crucial as it marks the transition where hair slows its growth and prepares for shedding. In the telogen phase, hair rests without growing, but new hairs begin to form beneath the surface. Lastly, the exogen phase involves shedding, where it is natural to lose around 100 hairs daily. Familiarizing yourself with these stages can help you understand why hair care practices matter; for example, maintaining a healthy diet rich in vitamins supports the anagen phase, ensuring optimal growth. Additionally, gentle washing and not over-styling can minimize excessive shedding during the exogen phase. With the right knowledge and care practices informed by the science of hair, individuals can promote healthier hair and recognize when changes may indicate a need for better self-care or consultation with a specialist.
