Hair is an fascinating aspect of everyone, men, women, young and adults. Everyone wants a shiny head full of hair. It not only plays a role in giving one a good appearance but also serves important functions, such as protecting the scalp and the brain from harsh sun rays and varying weather conditions. But have you ever wondered how hair grows? To understand hair better, you need to look at the hair growth cycle. Each hair goes through these phases in their lifespan. This cycle has three main stages: anagen, catagen, and telogen. Let’s explore each stage and what happens during them.
The Three Stages of Hair Growth
1. Phase 1: Anagen
The first stage of the hair growth cycle is named anagen. Also known as the "growth phase." During this time, hair is actively growing. The anagen phase can last for several years, usually between 2 to 6 years, but sometimes even longer.
In this phase, hair follicles are very active. They produce new cells that form the hair shaft. Where the hair grows longer and thicker. The length of the anagen phase varies from person to person and can depend on genetics, age, lifestyle and health conditions.
For example, people with long hair usually have a longer anagen phase. If you notice that your hair grows quickly, you might have a strong anagen phase. It’s also the stage where hair receives nourishment from the body, which is important for healthy hair growth.
2. Phase 2: Catagen
The second phase is the catagen phase of the hair growth cycle. This stage is much shorter than the anagen phase, lasting about 2 to 3 weeks. During this time, hair growth slows down, and the hair follicle begins to shrink.
This phase is like a transition period. The hair stops receiving nutrients, and the lower part of the hair follicle begins to break down. At the end of the catagen phase, the hair is no longer attached to the follicle, and it gets ready to shed. While the hair is still in your scalp, it is called a "club hair." This is a natural part of the cycle, and it prepares the hair for the next stage, which is shedding.
3. Phase 3: Telogen
The final stage of the hair growth cycle is telogen phase. This phase can last anywhere from 3 to 4 months. During this time, the hair is resting. It is not growing, and the hair follicle is at rest.
At the end of the telogen phase, the old hair is ready to fall out, making way for new hair to grow in the anagen phase. It’s normal to lose about 50 to 100 hairs a day during this phase. This shedding can happen more often if you are stressed, not eating well, or facing health issues, click here to read the common health issues that cause hair fall.
How the cycle works together
These three phases work together in a cycle. Not all your hair is in the same phase at the same time. Some hairs are in the anagen phase, while others are in catagen or telogen. This is why you don’t lose all your hair at once, even if you are going through a shedding phase.
The cycle also means that hair grows at different rates. For example, the hair on your head may grow faster than the hair on your arms or legs because of the differences in the anagen phase length for each body part.
Factors Affecting Hair Growth
Several factors can influence how your hair grows and how quickly it cycles through these stages. Here are a few important ones:
Genetics
Genetics play a significant role in your hair growth cycle and hair type. If your parents had thick, fast-growing hair, there is a good chance you might too. Conversely, if they experienced hair thinning or slow growth, you might face similar issues.
Age
As we age, our hair growth cycle changes. The anagen phase can shorten, leading to thinner hair or slower growth. Many people notice changes in their hair in their 30s and 40s.
Hormones
Hormonal changes can significantly affect hair growth. Conditions like pregnancy, menopause, and thyroid issues can alter the hair growth cycle. For example, some women experience thicker hair during pregnancy due to hormonal changes, while others may notice hair loss afterward.
Diet and Nutrition
What we eat plays a vital role in our hair health. Definitely, a diet rich in vitamins and minerals supports healthy hair growth and less hair fall. Nutrients like iron, biotin, selenium, vitamin D, and zinc are especially important. Poor nutrition can lead to weak hair and a slower growth cycle.

Stress
High levels of stress can also impact hair growth. When we are stressed, our body goes through changes that can lead to increased shedding. It’s essential to manage stress through activities like exercise, meditation, or hobbies to help maintain a healthy hair cycle.
Health Conditions
Certain health conditions can affect hair growth as well. Conditions like alopecia areata, scalp infections, and other medical issues can disrupt the hair growth cycle. If you notice sudden hair loss or changes in your hair, it’s a good idea to consult a healthcare professional.
