Here are some of the main causes of hair loss:
Diet poor in nutrients and vitamins
Some nutrients strengthen hair, such as minerals, proteins, zinc, iron, and vitamins A and C. Their absence in the body can cause hair loss.
Too much stress
Stress and anxiety cause an imbalance of the cortisol hormone. When excessive in the body, it can cause telogen effluvium. It is characterized by generalized hair loss and hair growth interruption.
Menopause and andropause
In women, menopause is a natural aging process in which the ovary stops producing estrogen. Andropause occurs in men. It happens when testicles decrease testosterone production, provoking a hormonal change that can cause hair to fall out more frequently.
Iron deficiency anemia can cause excessive hair loss, as iron is an essential mineral for hemoglobin production, a protein that carries oxygen from red blood cells to the scalp. If you receive less oxygen and nutrients, this can cause hair to weaken and lose.
Using synthetic products
Using synthetic products, such as formaldehyde, straighteners, dyes, and bleaches, weakens the hairs, causing them to fall out.
An infection called tinea or ringworm can lead to excessive hair loss, besides causing intense scalp itching.
Alopecia areata is a disease caused by genetic factors or autoimmune diseases such as vitiligo and lupus, which cause hair to fall out quickly from the head.
