The most common cause of hair loss is an inherited condition known as androgenic alopecia, male pattern baldness, or female pattern baldness. This condition usually occurs with aging. However, there are other factors that can lead to hair loss, such as poisoning oneself with arsenic, thallium, mercury, lithium, or warfarin. Additionally, taking large amounts of vitamin A or selenium can be toxic and cause hair loss.
Other causes of hair loss include pregnancy, thyroid disorders, anemia, autoimmune diseases, polycystic ovary syndrome (PCOS), and skin conditions such as psoriasis and seborrheic dermatitis. To prevent hair loss, it is important to follow a healthy diet that provides the necessary nutrients in terms of vitamins, minerals and proteins. It is also important to be aware that certain hairstyles such as braids or tight ponytails can cause traction alopecia. In addition, any medications, diseases, infections, or chemicals that interfere with the hair cycle can prevent hair from forming properly.
Both men and women can develop this type of hair loss which is the most common cause of hair loss worldwide. Women may notice a widening part in their hair or more scalp when their hair is pulled back. Fortunately, many causes of hair loss can be successfully treated if the underlying cause is identified. Anagen effluvium causes large amounts of hair to fall out rapidly during the anagen (growth) phase of the hair cycle.
Hair grows on almost every surface of the skin except for the palms of the hands, soles of the feet, lips, or eyelids. Women are nearly as likely as men to experience hair loss or thinning. If you think a medication is causing your hair loss, ask your doctor if it is a possible side effect. Premenopausal women should not take medications for the treatment of hair loss without using contraceptive methods.
While hair loss isn't dangerous in and of itself, it can be upsetting for those who experience it. Most people lose between 50 and 100 locks of hair per day.
