Hair loss and its treatments in men and women involve a deep understanding of hormones like testosterone, DHT, and estrogen. Testosterone, produced from cholesterol, is crucial not only for muscle building and libido but also for heart and brain health. Low testosterone levels can lead to heart disease, stroke, and Alzheimer's disease.
The conversion of testosterone to DHT via the enzyme 5-alpha reductase is a key factor in male pattern baldness. Medications like finasteride and dutasteride can inhibit this conversion, potentially reducing hair loss in genetically predisposed individuals. It's important to note that taking finasteride doesn't decrease testosterone levels; it may slightly increase them by preventing their conversion to DHT. However, this doesn't typically lead to a significant rise in estrogen levels, especially at the low doses used for treating hair loss.
The body's regulation of testosterone involves a feedback loop with the hypothalamus and pituitary gland, which helps maintain hormonal balance. While there's some concern about increased estrogen levels when using finasteride, it's generally not an issue at the recommended dosages.
In cases where exogenous testosterone is used, there might be a need to adjust the finasteride dosage to manage DHT levels effectively. However, hair loss treatment should always be tailored to the individual's needs, as it's not a rapidly progressing condition. Regular monitoring and adjustments can help achieve the best results without significant health risks, such as increased prostate cancer risk.
