Does Drug-Induced Hair Loss Fall Out the Same Way as MPB?

Dear Doctors:

I am a 22 year old male with mildly active Crohn’s Disease and in the next few weeks I hope to be going on Humira. I know that both the disease and the Humira can cause hair loss.

My question is this: Does hair loss from drugs and disease miniaturize and fall out in the same fashion as MPB? I would like to know if there is a difference, because if it’s the disease/drugs, I can’t do anything about it and no need to waste money on it either. Thanks for reading.

The biggest difference is that in male pattern baldness, there is a pattern to the hair loss, as seen in the Norwood classification chart (see below). Drug induced hair loss is usually generalized loss all over the head without a pattern.
