Hereditary hair loss usually develops when hair follicles gradually shrink due to genetic and hormonal factors. Hair may gradually become thinner, weaker and less dense, especially near the crown or front scalp. Stress, poor nutrition, dandruff, smoking, lack of sleep, or frequent chemical hair treatment can sometimes worsen the thinning process. Treatment usually focuses on slowing further hair loss and supporting healthier hair growth. Doctors may suggest medicines like minoxidil or finasteride in suitable adults, depending on age, gender, and overall health. Regular use is often needed for several months before visible improvement appears. A diet rich in protein, iron, zinc, omega-3 fatty acids, eggs, nuts, fruits, and green vegetables may support scalp and hair health. Gentle hair care, controlling dandruff, reducing stress, and avoiding excessive heat styling may also help protect existing hair. A doctor review may help if the hair fall becomes sudden, patchy, rapidly worsening, or associated with scalp itching or redness.
