Hair loss occurs for many reasons, including hormonal fluctuations during and after pregnancy, excessive heat exposure, fungal infections, genetics or chronic autoimmune diseases such as lupus and alopecia areata, notes Prevention. Dermatological skin conditions such as psoriasis and seborrheic dermatitis are also known to lead to hair loss.
Prevention explains that many women who are diagnosed with polycystic ovarian syndrome suffer from irregular hair growth on areas of the body such as the face and arms, but they may see hair loss occur on the head due to hormonal imbalances caused by the ovaries. Simple blood tests are available to diagnose any form of hormonal imbalance, and a family practitioner can prescribe various forms of hormone replacement therapy or birth control to restore hormone levels to normal.
Iron deficiencies and full anemia are known to cause hair loss in people who do not get enough of the mineral in their foods. To combat this, Prevention suggests adding iron sources to the diet, such as eggs, leafy greens, salmon, animal organs, beef, beans and fortified cereals. If dietary changes do not improve hair loss, people can try over-the-counter supplements that contain ingredients such as silica, biotin, iron and L-cysteine. For those who suffer from hereditary hair loss, products such as Rogaine can be applied to the scalp daily to encourage hair growth or at least slow the rate of hair loss, notes Prevention.
