Hair loss can occur differently among each individual and can be due to a variety of reasons. The most common cause of hair loss is a hereditary condition referred to as androgenic alopecia, also known as male or female pattern baldness. Hair restoration helps those suffering from a condition such as androgenic alopecia by blocking the further effects of DHT, a chemical known to be one of the main influencers of genetic hair loss. Along with other hereditary conditions, hair loss can also happen due to hormonal changes (menopause and pregnancy), infections, physical and emotional stress, diet, dramatic weight loss, aging, chemotherapy, and a handful of other medical treatments and prescriptions.
