Hi. I came across this forum because I was searching for answers for my thinning hair. I have only tried one product and that was restoration hair (natural product). Gave it up so I'm back to find something that get real results.
If you live in the USA then minoxidil (Rogaine) is over-the-counter. Spironolactone is a prescription drug that is best obtained through your doctor... Though you can buy such a medication online. I buy mine from http://www.inhousepharmacy.com.
Spironolactone is a tablet, available in various dosages. I'd go see a dermatologist to determine the correct dose for yourself.
As for minoxidil, it's the ingredient in Rogaine, which I'm sure you're familiar with. They have 2% and 5% minoxidil on the market and I think they have a Rogaine for women as well.
Female hair loss is kinda complicated so I'd just go see a derm and tell them about these two meds and see what they think.
I think Rogaine for women may be exactly the same as 2% Rogaine. I read the ingredients for Equate Women's minoxidil and it was the same as Rogaine 2%.
btw, i think you were given good advice here. spironolactone and minoxidil 2% do sound like they'd be the best treatment options for women.
