5. Nutritional Deficiencies
Low intake of iron, zinc, biotin, protein, and Vitamin D directly weakens hair structure. Even crash diets or poor gut health can limit nutrient absorption.
6. Harsh Hair Styling and Heat Damage
Frequent blow-drying, straightening, or using alcohol-based gels causes microdamage to hair shafts and follicles. These effects are cumulative.
7. Tight Hairstyles and Headwear
Constantly tying hair back or wearing tight caps/helmets can trigger traction alopecia—hair loss from repeated pulling on roots.
8. Hormonal Imbalances
Beyond testosterone, imbalances in thyroid, insulin, or DHT (dihydrotestosterone) levels can shrink follicles. A blood panel can reveal hidden hormone issues.
9. Environmental Pollutants & Water Quality
Hard water, UV rays, and air pollutants strip hair of protective oils and cause buildup on the scalp, suffocating follicles.
10. Sudden Weight Loss or Crash Dieting
Extreme calorie deficits confuse your body into survival mode—halting hair growth to conserve energy. Hair becomes brittle and starts shedding within weeks.
