Why is there such a huge price difference for hair loss treatments?

Lately, I have been experiencing significant hair loss and the volume on the crown of my head seems to be dropping drastically, causing me severe stress. I feel I need to start professional care before it's too late, so I looked into a few places. However, the prices for hair loss treatments are higher than I expected, and I am confused about whether I should proceed. The overall cost of hair loss treatments is quite a burden. Of course, as a working professional, I am willing to invest, but I hesitate to pay a large sum upfront when the effectiveness is uncertain. Maypure, I would like to know what the average price range is for initial hair loss treatments. I would also like to know if this is covered by private health insurance.
