types of hair loss

                          There are several types of hair loss, as follows

• Androgenic alopecia: This is the most common form of hair loss and is also referred to as male-pattern or female-pattern baldness. Hormones and genetics seem to play the main role here. Male-pattern baldness is hereditary, from either side of the family, and can even skip generations. It tends to occur on the crown and at the temples and when these patches join together, the top of the hair is left completely bald. Statistics show that this type of hair loss affects 30 percent of men aged 30, 50 percent of men aged 50, and 70 percent of men aged 70. For women, the hair thins initially on the frontal area and the crown and moves down the sides of the head, while the back of the head remains dense with hair This is hereditary and tends to affect women mostly after menopause.

• Toxic alopecia: This type of hair loss seems to occur following physical or emotional stress. Things such as illness, scalp infections, sudden loss of weight,  drugs, and pregnancy/childbirth can cause this type of hair loss. Diseases such as lupus, diabetes, and thyroid disease can bring about such hair loss, as can chemotherapy, heart disease drugs, and radiation therapy. Hair loss that occurs as a result of a mental or physical can occur some 2 to 3 months after the event that sparked the stress.
• Alopecia areata: This is actually a skin disorder which causes hair on the affected skin areas to fall out. It is usually the scalp or beard and is thought to have autoimmune causes. This type of hair loss seems to be most common in young people. The hair usually grows back.
• Alopecia universalis or totalis: All body hair is lost, from everywhere, including eyebrows and eyelashes Hair follicles are not destroyed; the inability to grow hair back is psychological and getting hair to grow back again is not easy.
•   hair loss due to hair pulling, a habit or condition that can be corrected with treatment.
• Scarring alopecia: This is hair loss that occurs at the site of scars or damaged areas such as burns or skin cancer.
