Only time will tell. The good thing is the supplement will last 2 months at the recommended dosage, works out a $1 a day with shipping. It comes in a very small bottle. I've ordered my 2nd bottle even though I am only a week into the first. I'm happy if it continues to slow down my shedding, improve my cholesterol and energy.
My recommendation is to stick with what your doing, I don't think your hair has gotten worse the last few months.
It certainly looks and sounds like you have male pattern baldness but your planning to see a derm might as well wait and get it confirmed before doing anything crazy.
