Understanding The Science of Hair Growth

Have you ever wondered what makes your hair grow, or why some people have thicker and faster-growing hair than others? What habits affect your hair growth and can you actually influence your hair growth? The hair growth cycle is an intricate one and in this article we will delve deep into the hair growth cycle, exploring the scientific intricacies behind the process and the factors that influence it.

Understanding the Hair Growth Cycle

Hair growth is a complex biological process that occurs in a cycle consisting of three main phases:

1. Anagen Phase: This is the active growth phase where hair cells divide rapidly, leading to the formation of new hair. During this phase, hair can grow at a rate of up to half an inch per month. The length of the anagen phase is largely determined by genetics and can last anywhere from two to seven years.
2. Catagen Phase: Also known as the transitional phase, catagen is a short period lasting about two weeks. During this phase, hair follicles shrink and detach from the dermal papilla, signaling the end of active growth.
3. Telogen Phase: Telogen is the resting phase that lasts around three months. In this phase, hair doesn't grow, and it's eventually shed to make room for new hair in the next anagen phase.

Factors That Influence Hair Growth
