Nutrient Deficiencies May Contribute to Worsening Hair Loss
Some hair shedding is normal, but much more hair loss can have many causes.
These causes can include stress, illness, hormones, genetics, medicines or not getting enough nutrients.
Low iron, vitamin D, vitamin B12, folate or zinc may be linked with hair shedding in some people.
Not eating enough protein can also affect hair growth.
A possible link does not prove that a nutrient shortage caused someone’s hair loss.
Taking many supplements without testing can be harmful.
A doctor can review the person’s diet, health history and hair-loss pattern.
People should see a dermatologist if hair loss is sudden, persistent, patchy or accompanied by scalp problems.
Iron, vitamin D, vitamin B12, folate and zinc deficiencies may be associated with increased hair shedding.
Inadequate protein intake, restrictive dieting and rapid weight loss can affect the hair growth cycle.
Hair loss may also result from genetics, hormonal changes, stress, illness, medications or scalp conditions.
Doctors may recommend blood tests based on symptoms, diet and medical history rather than assuming a deficiency.
People should avoid unnecessary supplements and seek medical advice for sudden, persistent or worsening hair loss.
