Will hair shed by minoxidil grow back?

Yes. Mixoxidil stimulates the growth of new, healthier hair follicles (anagen follicles).  This new anagen hair naturally pushes out the older miniaturized hair. Therefore, when shedding occurs after starting minoxidil, it means the medicine is working. This temporary shedding is generally a good sign and is a reason to continue the medication, rather than stop. 

Minoxidil can sometimes cause a small telogen hair loss, this recovers quickly and is never permanent. I recommend getting a formal consultation with a hair loss expert. The best options are PRP and progesterone injections to the scalp and/or hair transplantation.  Best, Dr. Emer.

Thanks for your question. The initial shed of minoxidil grows back... for the vast majority. That being said, I have seen cases where the minoxidil shed did not grow back, and sadly, nothing in medicine is ever truly 100%.   In these situations, there are additional treatments (PRP, etc) that can be started to additionally stimulate growth and reduce shedding. I would say based on the numbers, your shed will likely be temporary and your hair will very likely grow your hair back if you stay on the minoxidil.  Hoping for a full, dense head of hair for you in the coming months. My best,  Dr. P.

Are you a man or a woman?  For men, the most likely diagnosis would be genetic hair loss not CTE, but get a doctor to diagnose you. Minoxidil is the standard treatment for CTE;however, this drug does not stop the cause of the CTER and for that you need to identify a cause if that is what you have.
