Hair fall is a prevalent issue affecting individuals of all ages, and while occasional shedding is normal, excessive loss can be concerning. Nutritionist Nmami Agarwal identifies four primary causes of hair loss: chronic stress, which elevates cortisol levels and forces hair follicles into a resting phase; hidden nutrient deficiencies in essential minerals and vitamins that impair hair growth; gut dysbiosis, which disrupts nutrient absorption and triggers inflammation; and chemical overload from harsh styling products that damage hair structure. To combat hair loss, Agarwal recommends maintaining a balanced diet, staying hydrated, and adopting a healthy lifestyle. These steps can help not only reduce hair fall but also support healthier hair growth over time.
