Hair fall lasting for 6 years with gradual thinning usually suggests a long-term condition rather than temporary shedding. Common reasons include genetic hair loss (androgenetic alopecia), chronic dandruff or scalp inflammation, nutritional deficiencies like low iron or vitamin D/B12, thyroid imbalance, stress, or sometimes a combination of these factors. When hair density keeps reducing over time, it often means the hair roots are slowly becoming weaker, so early control is important to slow further loss. Management usually works best with a combined approach. Keeping the scalp healthy with a mild shampoo and controlling dandruff or itching is important because inflammation can worsen shedding. A balanced diet with enough protein, iron, and vitamins supports hair growth from the inside. Regular sleep, stress control, and avoiding harsh chemical treatments, heat styling, or tight hairstyles can also help reduce stress on the hair roots. In cases of progressive thinning, medical treatments like topical growth-supporting solutions are commonly used, but they should be started only after proper evaluation of the cause. Since this has been ongoing for many years, it is important to get a dermatologist's assessment to identify whether it is mainly genetic or deficiency-related, so treatment can be targeted properly and further hair loss can be slowed effectively.
