What Is Alopecia?
Hair loss (alopecia) can affect just your scalp or your entire body, and it can be temporary or permanent. It can be the result of heredity, hormonal changes, medical conditions or a normal part of aging. Anyone can lose hair on their head, but it's more common in men.
What Causes Alopecia?
• Genes and Hormones
• Stress. Telogen effluvium is a type of alopecia where hair sheds in excess.
• Nutritional deficiencies, including low iron or vitamin D, could cause alopecia.
• Thyroid Issues. The thyroid is a neck gland that controls metabolism-related hormones. Both low and overactive thyroid can trigger alopecia.
What Are the Symptoms of Alopecia?
• Gradual thinning on top of head
• Circular or patchy bald spots
• Sudden loosening of hair
• Full-body hair loss
• Patches of scaling that spread over the scalp
