Hair Loss

Why Does Hair Loss Happen?

The typical scalp hosts an average of approximately 100,000 hairs, with a normal daily shedding rate of around 100 hairs.

However, as individuals age, a gradual increase in hair loss occurs, influenced by genetic factors affecting both men and women. Termed inherited hair loss, this phenomenon afflicts approximately half of the population by the age of fifty. Individuals with a genetic predisposition to hair loss exhibit heightened sensitivity to testosterone, resulting in the contraction of hair follicles.

Men, in particular, produce higher quantities of testosterone, leading to the initiation of hair loss as early as 21 years of age, with a substantial proportion experiencing bald patches by the age of 40.

Women, on the other hand, encounter increased hair loss post-menopause, typically after the age of 45. Nevertheless, fluctuations in hormone levels due to variations in the menstrual cycle, childbirth, and the use of birth control pills may induce hair loss even before menopause, albeit often reversible.

In summary, genetic factors contribute to inherited hair loss, with men generally experiencing earlier onset and a higher prevalence, while women may encounter increased hair loss following menopause, influenced by hormonal shifts related to various life stages.

What Can Affect Hair Loss

While hair loss is commonly associated with aging, it can affect individuals of all ages, including children. Ringworm of the scalp is a prevalent cause of hair loss in infants, while trichotillomania, a stress-related compulsive behavior involving the pulling out of hair from various body regions, is more common among teenagers and young adults.

Malnutrition, characterized by deficiencies in protein and iron, has been specifically linked to hair loss in individuals of any age. Studies also indicate a correlation between excessive smoking and hair loss. Adopting a healthier lifestyle often promotes the regrowth of hair in such cases.

Alopecia areata, a condition targeting hair follicles, results in round-shaped hairless patches on the scalp and the body, or overall thinning hair. It typically takes nearly a year for individuals with alopecia areata to regrow their hair.

Thyroid diseases, including hypothyroidism and hyperthyroidism, may lead to hair loss if left untreated. Rarer diseases such as lupus and syphilis can also contribute to hair loss, with regrowth often occurring upon proper medication.

Cancer, untreated or treated with chemotherapy, can result in non-permanent hair loss. Additionally, certain medications or medical treatments, such as blood thinners, may cause hair loss in some individuals, though not permanently.

Certain hair grooming practices, including the use of hair dyes, curling irons, and specific hairstyles, can weaken hair and contribute to hair loss. This and the above reasons are why many patients opt for HTN to address these issues.

Conclusion
