The Basic Process and Importance of Hair Growth

The process of hair growth can be divided into three stages: the anagen phase, catagen phase, and telogen phase. During the anagen phase, hair follicles continuously produce new hair, a process that can last from 2 to 7 years. This is followed by the catagen phase, during which hair ceases to grow and begins to shed, typically lasting for several weeks. Finally, there's the telogen phase, where hair growth stops but remains within the follicle, lasting approximately 2 to 4 months. The importance of hair growth lies not only in its contribution to one's appearance but also in its role in protecting the scalp and regulating body temperature.

The Four Cycles of Hair Follicle Growth

Hair begins at the follicle, undergoing cycles of growth and shedding. The follicle cycle resembles the four seasons, including the anagen phase, catagen phase, telogen phase, and exogen phase, which repeat in a continuous cycle. Each follicle undergoes independent cyclical changes, even adjacent follicles may not be in the same growth phase. The characteristics of these four cycles are as follows:

Anagen Phase

The growth phase lasts 2-6 years, much like spring and summer. Hair is bathed in ample sunlight and rain during this time, with approximately 85% of hair in the growth phase. Hair falls out daily, but it does not affect one's appearance. Hair follicle stem cells are not indefinitely active; after 2-6 years of growth, they enter the next follicle growth stage, the catagen phase.

Catagen Phase

This is a transitional phase, lasting 2-3 weeks. The follicle shrinks and sheds during this time. Approximately 1% of hair is in this phase at any given time, similar to autumn. The follicle is in a contracted state during this phase, and some hair shedding is a normal phenomenon.

Telogen Phase

This is a relaxation phase, lasting about three months, with approximately 10-15% of hair in this phase, similar to winter. The follicle is in a dormant state, and hair sheds, but the follicle remains viable. Hair loss is actually due to the follicle entering the resting phase and being unable to enter the next growth phase.

Exogen Phase

This is part of the resting phase, similar to spring. Old hair sheds, and new hair continues to grow. Healthy follicles resume the growth phase, and follicles and hair shafts grow again. As long as life continues, follicles will continue to cycle through growth, continually producing hair shafts, which then shed.

Factors Influencing Hair Growth

Genetic Factors

Family genetics may affect the speed of hair growth, hair quality, and hair loss patterns.

Nutrition

Adequate intake of protein, vitamins, and minerals is crucial for healthy hair growth.

Hormones

Hormonal imbalance may lead to hair problems, such as excessive androgen levels contributing to hair loss.

Stress

Prolonged stress and anxiety can affect blood circulation, impacting hair health.

Environmental Factors

Climate, pollution, UV exposure, and other environmental factors can also influence hair growth.

To maintain healthy hair, the number of hair follicles in the growth phase must exceed the number of hair follicles in the resting phase.

Are there any effective methods to accelerate hair growth?

Actually, the rate of hair growth varies from person to person, depending on genetics, daily nutritional intake, and hair care habits. However, there are some methods circulating in the community to accelerate hair growth, which can be referred to:

Scalp Massage

Research suggests that scalp massage can promote blood circulation, stimulating hair growth. Massaging the scalp with a wooden comb for 2-3 minutes twice a day can promote hair growth.

Balanced Diet

Diet is crucial for hair growth. It's important to supplement with high-quality proteins such as fish, meat, eggs, beans, and dairy products. Additionally, black sesame is an excellent choice for strengthening hair roots. It is generally recommended to consume 0.8 to 1 gram of protein per kilogram of body weight per day, and the specific intake can be adjusted according to individual circumstances and dietary habits.

Regular Hair Trimming

Regularly trimming split ends can help nutrients be fully absorbed by healthy hair, allowing hair to grow healthily.

Stress Reduction

Taking stress-reducing measures such as meditation, yoga, or deep breathing can help alleviate stress and improve hair health.

Moderate Exercise

Regular moderate exercise can enhance overall health, improve blood circulation, and promote hair growth.

Adequate Sleep

Maintaining adequate sleep is conducive to body repair and metabolism, which also positively affects hair growth.
