3 stages of hair development
According to Dr. Stuti Khare Shukla, dermatologist, founder of Elements of Aesthetics and Haila Growth Booster (India), hair growth takes place in cycles and 3 separate stages: the anagen phase, the catagen phase and the telog stage. Each stage plays an important role in hair growth and loss, this cycle will be repeated continuously.
Dr. Stuti Khare Shukla details about each stage, including:
The period of anagen (development stage)
This phase lasts from 2-7 years, depending on genetic factors, health and other external factors.
This is the strong growth stage of the hair, when the new hair is formed from hair follicles and grows long. Each hair follicle may have 1-3 hair growing at the same time in this period. Hair can grow about 1 cm per month during the Anagen period.
Catagen period ( transitional phase)
The catagen stage lasts about 2-3 weeks. This is the transition period, when the hair stops growing and the hair follicle starts to shrink. The cells in hair follicles stop producing keratin and hair begins to separate from the blood vessels to nourish hair follicles. At this time, the hair will be called "hair prepared".
Telogen phase (resting phase)
The telogen period lasts about 3-4 months. This is a period of rest, when hair no longer grows but has not yet fallen out. Hair is still in the hair follicles but has not developed further. During this period, hair follicles are starting to prepare for creating a new replacement hair. When new hair grows from hair follicles, old hair will be pushed out and lost.
How does the hair cycle repeat itself?
After the telogen phase, the hair will shed and a new hair will grow from the same hair follicle, starting the development cycle from the Anagen period. This process can take place continuously for a lifetime.
Factors affecting hair cycle
Genetics: Genetic is the main factor determining the hair cycle of each person, including the time of each stage.
Hormone: Hormone changes in the body (such as during pregnancy, age, hormonal changes) may affect hair cycle, cause hair loss or change hair growth.
Stress: Prolonged stress can affect the hair cycle, increasing the number of hair to the telogen phase, leading to a lot of hair loss.
Diet: Lack of vitamins and minerals (such as iron, zinc, biotin) can reduce hair health and disrupt hair cycle.
Notes
Dr. Stuti Khare Shukla emphasizes that each stage in the hair cycle has its own characteristics and needs. Understanding this helps you choose the right hair care products and apply the necessary treatment measures.
If you notice too much or abnormal changes, through the hair development cycle can help you identify whether it is caused by a problem such as nutritional deficiencies, stress or other pathologies caused or Are not.
