Hair Cycle

The human hair cycle is an important part of the body's natural process of skin renewal. This cycle is divided into three different phases: anagen, catagen, and telogen. Each phase of the hair cycle reinforces and replaces the hair on the head and causes changes in the structure of the hair. The anagen phase, also known as the active growth phase, typically lasts for two to six years. During this phase, hair cells rapidly divide and move upwards the inside of the hair follicle. This rapid division of cells is what causes the hair to remain at its regular length and thickness. After this stage, the cells start to die off and are replaced by new cells, causing my hair shaft to become wider and shorter. The next phase of the hair cycle is the catagen phase, also called the regressive phase. During this stage, the outer sheath of the follicle begins to shrink and the hair begins to detach from its base. Also, the base of the follicle stops producing new cells, resulting in a shorter hair. This stage usually lasts for two to three weeks. The last phase is the telogen phase, or resting phase. During this stage, the hair follicle is completely dormant and does not produce new cells. It generally lasts for around 100 days. At the end of this phase, the old hair is shed and a new anagen phase begins. The repeated cycles of the hair cycle are important to maintain healthy hair growth and to prevent hair loss. The hair cycle also affects the texture, color, thickness, and overall appearance of the hair. With the help of regular in-salon trims and treatments, and proper at-home hair care, people can manage their hair cycles and ensure that their hair remains healthy.
