Is hair loss an indication of a health issue?
It can be, but not necessarily. Hair loss can be caused by many things, most common of which is androgenic alopecia more commonly referred to as female or male pattern baldness. This is not indicative of a health problem or concern.
Other non-genetic causes of baldness conditions however, can be caused by health related issues such as a poor diet, traumatic stress, scalp infections such as dermatitis or psoriasis, iron deficiency, a thyroid condition, etc. Certain types of alopecia can even be caused by certain medications or can be a reaction to a hormonal change in the body.
A dermatologist or hair loss doctor will be able to find the cause of your balding condition and recommend the best treatment option for you.
