I have thin hair due to hypothyroidism. I've been taking Armour Thyroid for about 4 months now. I thought my hair would improve with the medication, but so far it hasn't changed. Yesterday my husband noticed how thin my hair is and suggested I try Rogaine.

Is it an option for this condition? Has anyone tried it? What are the risks? Do you have to use it forever once you start? Will it change the texture of my hair?
Mostly 2A; Fine and wavy
