The four stages of hair growth are anagen, catagen, telogen, and exogen. Each stage plays a crucial role in the life cycle of hair.

In the anagen phase, hair is actively growing, which can last for several years. This is the longest stage and is critical for establishing the length of the hair.

The catagen phase follows, representing a transitional period where hair growth slows, and the hair follicle begins to shrink. This stage lasts a few weeks and marks the end of the active growth phase.

Next is the telogen stage, during which the hair is in a resting phase. Hair is not actively growing but is still attached to the follicle. After a few months in this stage, the hair will eventually shed, leading into the final phase.

The exogen phase refers to the shedding of hair, which is a natural part of the hair cycle. This phase is when the old hair falls out and makes way for new growth, allowing the cycle to restart.

This understanding of hair growth stages is essential for anyone in the cosmetology field, as it helps in hair care, treatments, and addressing client concerns effectively.
