Rogaine 5% worked after 2 weeks once daily, once switched to every other day it stopped. Will it work again?

Hair hair loss in women is multifactorial. You need to determine the etiology of your hair loss. This can usually be accomplished with a consultation that includes history, examination with magnification and woods light, blood work and possibly biopsy. Rogaine (oral and topical)  is excellent for telogen effluvium and female pattern hair loss. Spironolactone when added has shown to be helpful for female pattern alopecia ( Sinclair).

It can take up to 6 months to see results with Rogaine and if you stop using it, you will lose your results. I suggest seeing a hair loss expert now to evaluate and go over your condition and provide you information about your best treatment options. There are great non-invasive options like prp/progesterone and/or hair transplantation. See an expert. Best, Dr. Emer

With
your diagnosis of TE, you first have to treat the underlying cause – ie anxiety,
stress, or whatever it is.    Rogaine
does not work for everyone but you have proven to yourself that it worked in
the past. Keep in mind that Rogaine takes 6 months of daily use before you will
notice a difference.   So, give it more time.
