Sarcoidosis and Hair Loss

i have sarcoidosis. my hair is starting to fall out. i’m 29 male. please tell me if it will grow back

There is no way for me to know that your hair will grow back. You need a good medical examination and a correct diagnosis. Sarcoidosis is a multisystem disease of unknown causes. It affects more women than men. It affects all organ systems including the skin, which may contribute to hair loss. While sarcoidosis may be a factor in your hair loss, you may also have male pattern hair loss. There is no way to tell unless you get your hair mapped out for miniaturization and then follow-up with your doctor for his/her interpretation of that mapping pattern.
