What is a one-sentence summary of the following article?
Cutaneous lupus (lupus of the skin) can cause your hair to fall out. Alternatively, your hair loss may be a result of your medication, particularly if you are on a corticosteroid (like prednisone). Talk to your doctor to figure out which of these two reasons you're experiencing hair loss (also known as alopecia). Hair loss from lupus medications like corticosteroids is mostly reversible, but hair loss from scarring and discoid lesions is generally permanent. If you have been diagnosed with cutaneous lupus (lupus of the skin), you may quickly begin losing hair because the damage that lupus does to your skin can change the normal function of your hair follicles. The sooner you begin your treatment, the sooner you can reverse hair loss. If you haven't been diagnosed with lupus, but you have been losing hair, talk to your doctor about the possibility that you have lupus. There are lots of other reasons you could be losing hair (heredity, chemical hair treatments, thyroid issues, nutritional deficiencies, etc.), but if you're concerned, see a doctor. Particularly if you're also experiencing unexplained fevers, rashes, fingers and toes that turn blue in the cold, fatigue, and joint or muscle pain, there's a decent chance that you have lupus. The key to stopping hair loss from lupus is early treatment. In most cases, the best way to control hair loss is to control the disease. There are such a wide variety of lupus medications that the directions vary greatly. It's likely that you will need to take some at night, and some in the morning, some with food, and some without. Talk to your doctor or pharmacist about what to do if you miss a dose, because that will also depend on the kind of medicine you're taking.

Summary:
Determine if your hair loss is a result of your lupus or your medications. Begin your lupus treatment immediately. Take your medicine on time and as prescribed.
