I've been using Estradot 25 patches twice weekly for about six months. The only side effect I've experienced is hair loss. Although I regret the loss, my hair was quite thick to begin with so it doesn't look too bad. I'm worried, though, in case I just carry on losing hair for as long as I use the Estradot - I haven't got that much hair! Does anyone have experience of this? Does the hair loss stop once the body adjusts to the drug or does it just keep falling out? I do know that, if I just stop using the patch, the hair I've lost already won't grow back.
