Is it correct to visit a dermatologist for alopecia areata?

The groom has developed alopecia areata on his head...

Has it been a month or two since it started? Right now, hair is growing back almost like cotton...

Since I'm a man, after getting a haircut, it looks more distinct, and I find it unpleasant to look at...

My hair is thin, and I don't have a lot of volume either...

I even developed alopecia areata...

Can I just go to the dermatology clinic for treatment?

If I go and get treatment as soon as possible, my head will probably get better, right??

They say that alopecia areata can be contagious...

I don't want to see it... I have to go to work too... I can't even wear a hat and go...

Please introduce me to a hospital that is good for alopecia areata.

The area is Dasan~
