Understanding Hair Loss: Common Causes and Practical Advice
Hair loss is rarely the result of a single issue. Dermatologists point to several medical factors that can influence scalp hair health. In discussions with specialists from Hemotest laboratory, experts explain how hormonal balance, thyroid function, and overall metabolism shape the vitality of hair. A central topic is androgenetic alopecia, a form driven largely by dihydrotestosterone (DHT). When the body creates excess DHT, hair follicles can shrink over time, producing thinner strands and more shedding. This hormonal pattern is one of the most common culprits behind noticeable thinning for both men and women. Clinicians emphasize that the hormonal environment plays a pivotal role in hair vitality, and balancing hormones can help manage the condition. (Source: Hemotest laboratory)
If metabolic processes falter, hair tends to suffer first. Hair follicles respond quickly to energy shortages, nutritional gaps, and cellular stress. Dullness, increased breakage, and shedding can signal deeper systemic issues. Ongoing metabolic disturbances may magnify hair loss, underscoring the link between hair health and overall wellness.

Beyond hormones and metabolism, thyroid health stands out as another key factor. Both hypothyroidism and hyperthyroidism can alter hair growth cycles. When thyroid hormones misalign, the scalp often shows changes in hair density and texture. Proper evaluation of thyroid function is a common step in diagnosing the root cause of shedding and planning appropriate treatment. (Source: Hemotest laboratory)
Anemia is also cited as a contributor to hair loss. A complete blood count, along with measurements of serum iron, ferritin, and transferrin, can help identify iron deficiency or other anemias that may contribute to thinning hair. Correcting iron status and addressing anemia can improve hair regrowth in many individuals. (Source: Hemotest laboratory)
Diet and nutrition frequently surface in discussions about hair health. Dermatology specialists note that specific foods can support hair growth and reduce shedding as part of a balanced plan. Fatty fish, rich in omega-3 fatty acids, provides essential nutrients that may help support follicle function. Eggs supply high-quality protein and biotin, while leafy greens and vegetables like spinach contribute minerals and antioxidants. Nuts and avocados offer healthy fats that support overall hair vitality. A nutrient-rich diet, paired with medical management as needed, can play a meaningful role in improving hair condition over time. (Source: Hemotest laboratory)
Experts stress that hair loss is not always permanent. In some cases, addressing underlying health issues—whether hormonal imbalances, thyroid disorders, anemia, or nutritional deficiencies—can slow or reverse shedding. Regular medical assessment and tailored treatment plans are recommended to determine the most effective approach for each person. (Source: Hemotest laboratory)
From a practical standpoint, individuals experiencing noticeable shedding should consider a comprehensive health check. A clinician may review hormonal profiles, thyroid status, iron stores, and other relevant markers to form a clear picture of the cause. When a specific trigger is identified, targeted therapies, lifestyle adjustments, and nutrition strategies can be combined to support hair regrowth and resilience. (Source: Hemotest laboratory)
In summary, hair loss often signals broader health processes. While androgenetic alopecia remains common, thyroid issues, anemia, and metabolism all contribute to the overall picture. With careful assessment and a personalized plan, many people can improve hair quality and reduce shedding over time. (Source: Hemotest laboratory)
