When people conjure images of the elderly, they often envision heads gleaming with baldness or fringed with a horseshoe of silver hair the so-called "male pattern baldness."
In reality, baldness is not only prevalent among the elderly; with the advent of hectic work schedules and prolonged overtime, many office workers are facing premature hair loss, including receding hairlines and even complete baldness.
Some people find solace in the adage, "Less hair, longer life; bald heads belong to the long-lived." But is that truly the case? Let's delve into the relationship between hair, health, and longevity.
Factors Affecting Baldness
Researchers have discovered that men with sparse hair on the top of their heads appear to have a lower risk of developing cardiovascular disease. This revelation stems from the role of male hormones, specifically dihydrotestosterone (DHT), in hair loss.
DHT binds to hair follicles, causing them to shrink, leading to thinner hair strands and a shorter growth cycle, ultimately accelerating hair loss. However, DHT also plays a crucial role in the body by reducing low-density lipoprotein (LDL) cholesterol.
LDL cholesterol accumulates on blood vessel walls, potentially leading to blockages. Therefore, men who experience hair loss due to high levels of DHT may simultaneously reduce their risk of atherosclerosis, hypertension, and other cardiovascular diseases.
Nevertheless, the impact of excessive male hormones on the hair varies from person to person, a phenomenon that can be attributed to genetic coding. The sensitivity to hormonal changes is determined by inherited genes. Individuals with low DHT sensitivity experience little to no hair loss, while those with high DHT sensitivity are predisposed to premature baldness.
"Male pattern baldness" may sound like a condition exclusive to men, but women are not immune to it. In males, male pattern baldness typically manifests as hair loss on the sides of the forehead (the infamous "M-shaped hairline") and thinning hair on the crown. In contrast, female hair loss primarily affects the part of the hair, resulting in a widening part and thinning hair on the crown, while the front hairline remains intact.
Baldness Longevity
Based on the aforementioned study, one might infer that a shiny scalp signifies a low risk of cardiovascular disease. However, this is not entirely accurate. Baldness is merely a surface-level symptom, and we must look beneath the surface to understand the underlying causes.
1. Hereditary Hair Loss
Research indicates a strong genetic predisposition to male pattern baldness. Specific genetic markers, such as variations in the AR gene (androgen receptor gene) on the X chromosome, are closely associated with baldness. If a man's father or grandfather experiences hair loss, he is likely to have a higher risk of developing male pattern baldness.
2. Interference from Other Hormones
Apart from male hormones, fluctuations in other hormones can also affect hair follicle health and hair growth. Factors such as folliculitis, stress, smoking, postpartum hormonal changes, and certain autoimmune disorders can trigger or exacerbate hair loss. For instance, abnormal thyroid function can disrupt the hair growth cycle. In China from 2016 to 2017, two studies involving patients with hyperthyroidism found a potential link between thyroid dysfunction and hair loss. Furthermore, iron deficiency and metabolic disorders may also contribute to hair loss.
3. External Influences
In addition to internal factors, external forces can also lead to hair loss. The sight of cancer patients undergoing chemotherapy is a stark reminder that the drugs used to treat malignant tumors often cause extensive hair loss.
Fungal or bacterial infections can damage hair follicles, forming scars and resulting in permanent hair loss in the affected areas. Harsh hair dyes and styling products, as well as harmful gases emitted by building materials, new furniture, and paints (such as formaldehyde and benzene), can irritate the skin, compromising scalp health and damaging hair quality. Prolonged exposure to indoor environments with toxic chemicals can adversely impact hair health, underscoring the importance of maintaining good indoor air quality.
As evident from these examples, hair loss is not necessarily an indication of longevity or good health. In fact, some types of hair loss may serve as warning signs of chronic diseases or abnormal bodily functions.
Health Manifestations in Hair
While we cannot directly infer health status based on baldness, hair does serve as a mirror reflecting internal conditions.
1. Premature Graying
Apart from genetically inherited premature graying, a sudden development of gray hair may signal nutrient deficiencies. A lack of vitamins B1 and B2, iron, copper, and protein can all contribute to gray hair. In some cases, premature graying can also indicate an autoimmune disease or thyroid problems.
2. Brittle Hair
Hair that becomes rough, brittle, and resembles dry grass could indicate a nutritional deficit as well. The absence of Omega-3 fatty acids, vitamins A, E, and zinc can result in hair losing its elasticity and becoming dull and lifeless.
The hair growth cycle and hair texture are closely tied to the aging process of the body, and cellular health is directly linked to
