What you describe sounds like alopecia areata, an autoimmune disorder that causes loss of hair. Several different types of alopecia areata are classified according to the part of the body that is affected. Yours sounds similar to alopecia barbae, which affects facial hair in the way that you describe.

Alopecia areata affects between 1 to 2 percent of the population and is highly unpredictable. The condition can affect both men and women of all ages and races, but it most often appears first in childhood. Alopecia areata can go away on its own, or exist in cycles of hair loss and hair re-growth. Alopecia is the result of the body's immune system mistaking hair follicles as intruders and attacking them, preventing any hair growth in the area. While it usually starts with patches of hair loss, it can progress to a more total hair loss on the head (alopecia totalis) or even over the entire body (alopecia universalis). The condition doesn't kill the hair follicles, so hair growth can resume at any point spontaneously, and in some cases does.

Alopecia doesn't have any general effect on your health other than the hair loss, and is not indicative of any other disease.

A home remedy that I know is using garlic on the patchy areas. Crush a clove of raw garlic and apply it on the skin topically. Garlic boosts the immune system, and kills the harmful bacteria on the skin. I have seen that application of garlic on skin helps the skin to overcome this disease. However you have to be patient, since in some cases this may take up to a few weeks/months.

Eating a clove of garlic is very beneficial to the body as well for its great effects on the immune system. So you may consider taking a clove of raw garlic every day. Also make sure that you are taking a good daily vitamin (not a synthetic one, it should be natural like Solgar), and that you are taking essential fatty acids like flax seed oil and evening primrose oil.

Hi guys first post for me.
I think i have same or something similar. I am now 54 but first signs was 8 yrs ago. It started with a 5mm bald patch on the chin (i used to have full beard when younger) and now i have lost all side bearns and still receding which is scary. If i was to leave shaving for 5 days i look like a female Hitler!Sometimes hairs look to be growing back but if i get stressed again a week or so later they fall out. Now I do suffer from stress due to bad youth and am in the middle of a detox as we speak (methadone/Dexedrine ie:dexamphetamine) All prescribed which have stupidly got into due to Dex cut down. That aside i have a very good organic diet i juice not as much as i like and have recently got into supplements due to wife cancer. Hope this helps you.
