Why does the beard still grow after it is plucked? Revealing the scientific principles of hair growth
Many men are troubled by the fact that their beard will still grow back after being pulled out. This article will combine the hot topics and hot content on the Internet in the past 10 days to analyze the causes of beard regeneration from a scientific perspective, and attach relevant data for readers' reference.
1. Biological basis of beard growth
The growth of beard is closely related to the structure of human hair follicles. Hair follicles are tiny organs in the skin responsible for hair growth and have strong regenerative capabilities. Here are the key figures for the hair follicle growth cycle:
| growth stage | duration | Main features |
|---|---|---|
| Growth phase (Anagen) | 2-6 years | Hair follicles are active and hair continues to grow |
| Catagen | 2-3 weeks | Hair follicles begin to shrink |
| Telogen | about 3 months | Hair falls out and hair follicles become dormant |
2. Why does the beard still regenerate after plucking it?
1.Hair follicles are not damaged: Simple beard plucking will only remove the visible part, leaving the hair follicles intact. As long as the hair follicles are healthy, new hair will continue to be produced according to the growth cycle.
2.The role of stem cells: There are hair follicle stem cells at the base of hair follicles, and these cells have strong regeneration ability. Even if the hair is plucked, the stem cells activate a new growth cycle.
3.Hormonal effects: Androgens (especially testosterone) are key regulators of beard growth. As long as hormone levels are normal, beard growth will continue.

4. Common misunderstandings about beard growth
1.Pulling out your beard will make it grow thicker: This is a common misunderstanding. The feeling that your beard is thicker is because the new beard growth is blunt at the end, not because it is actually thicker.
2.Shaving changes growth rate: Shaving only affects surface hair and does not change the growth cycle or speed of hair follicles.
3.Certain foods can speed growth: While nutrition affects overall health, there are no specific foods that can significantly change the rate at which your beard grows.
5. How to scientifically manage beard growth
1.Prune regularly: Healthier than plucking, can avoid problems such as folliculitis.
2.Keep your skin healthy: Cleansing and moisturizing help hair follicle health.
3.accept individual differences: Beard growth speed and density are mainly determined by genes.
4.medical intervention: For cases where permanent removal is truly necessary, consider professional methods such as laser hair removal.
6. Expert opinions
Dermatologist Dr. Li pointed out in a recent interview: "The ability to regenerate beards is a characteristic retained by human evolution. Under normal circumstances, a single hair follicle can support 20-30 hair regeneration cycles. Deliberate and frequent removal of beards may cause hair follicle damage, and a gentler trimming method is recommended."
To sum up, whether beard will grow even after it is plucked is determined by the biological characteristics of hair follicles. Understanding this principle can help us adopt a more scientific approach to beard management and avoid unnecessary skin problems. If you need to change your beard growth pattern, it is recommended to consult a professional dermatologist.
