The main cause of hair loss is STRESS! Physical and psychological stress can cause hair loss, along with strain on the body such as going through childbirth. Several months after childbirth you can expect hair to fall out in shower etc. Also going through a trauma or recent illness can contribute to hair loss. Vitamin deficiency can impact hair loss, such as riboflavin, biotin, folate, and vitamin B12 deficiencies.
Can it maybe be something more serious ?
yes!, hair loss can also be a symptom of a larger medical issue a person may have, like hypothyroidism or lupus.You need to make an appointment with your GP and get tested if you believe your hair loss is not linked to stress.
