There is no single age at which people genetically lose hair. Hair loss, or alopecia, is a complex process influenced by a combination of factors, including genetics, hormones, and lifestyle.
Genetic Predisposition to Hair Loss
- Androgenetic Alopecia: The most common type of hair loss, often referred to as male-pattern baldness or female-pattern baldness, is largely influenced by genetics.
- Family History: If your parents or grandparents experienced hair loss, you are more likely to experience it as well.
- Specific Genes: Researchers have identified several genes associated with androgenetic alopecia, but the exact mechanism is still being studied.
Other Factors Influencing Hair Loss
While genetics play a significant role, other factors can also contribute to hair loss, including:
- Hormonal Changes: Hormonal fluctuations, particularly in men and women during puberty, pregnancy, and menopause, can affect hair growth.
- Medical Conditions: Certain medical conditions, such as thyroid disorders, autoimmune diseases, and nutritional deficiencies, can lead to hair loss.
- Medications: Some medications, like chemotherapy drugs, can cause temporary or permanent hair loss.
- Lifestyle Factors: Stress, smoking, and poor diet can also contribute to hair loss.
Age and Hair Loss
While genetics can predispose you to hair loss, the age at which it becomes noticeable can vary widely.
- Men: Hair loss often begins in the late teens or early twenties, but it can also start later in life.
- Women: Women tend to experience hair loss later than men, often after menopause.
It's important to remember that hair loss is a normal part of aging for many people. If you are concerned about hair loss, it's best to consult a dermatologist or trichologist for a proper diagnosis and personalized treatment plan.
