I also wanted to know what doctor do I take him.

I agree with what MLWTR has recommended -- have him checked out by his primary care doctor, in order to rule out any medical problem.

It is difficult for me to say anything definite about what's going on with your son.  Before I continue -- how old is he?  And have you heard anything from his school?

I'm wondering if he might benefit from being checked out by a physician. The weight loss is concerning, and malabsorption of nutrients could be causing the hair loss. There are many diagnostic possibilities, but one in particular you might want to ask about is celiac disease. It causes weight loss and malabsorption, but in addition can cause unusual psychological symptoms/behavioral change due to poor absorption of certain essential vitamins such as B12. The psychological problems and weight loss go away once the disease is properly managed. Best of luck.

My son is 16 years old.  I notice this about a year ago.
He likes to keep to himself.
He likes to bother his brother alot.  but his mean.  he tells his brother that he is fat.
I will try to buy b12 and will take him to the doctor to get check up.

Sounds like he could be developing an eating disorder, do not panic about this or force him to eat and such, he probably feels like he doesn't have control in his life and that he can only control his eating habits. Young people with this condition are often high achievers, and often try and seek attention from his parents, withdrawing from you hoping that you will follow through (show that you care). I say this because me and my sister suffered from eating disorders and it sounds extremely similar. We both wanted attention whether it was negative or positive and would rebel and get in trouble just to get that attention form one another. We would also lock ourselves in our rooms hoping that a parent would notice that we were gone, too see if they "cared" to check up on us. I hope this helps you out. Give you're son praise, try and involve yourself more in what he's doing. Every now and then, make his favourite meal, just because you thought "it would be nice" to encourage him to eat more, pack him school lunches rather than give him dinner money as it is extremely easy to "leave" the money at home and skip lunch.
Good luck and best wishes to you both x
