Were you on prednisone?
How sick exactly were you?
You might consider to change to Asacol?
Explain exactly how much you're losing and if it can be noticed such as receding hairline, top of head..etc?
Is it all over your head or in certain places?
You do know that it will take a few months before you even have hair coming back in...so...
Stress can exacerbate hairloss.
You won't lose it all....unless it runs in your family to lose it.
Did you have your testosterone checked?? high testosterone can cause hairloss as well.
