Is there anyway to grow back a receding hairline even a little bit?

Please do not suggest rogaine or hair transplant.Is there anyway to grow back a receding hairline even a little bit?
Take some estrogen but even though rogaine does not grow back hair it will stop it from falling out. I have PCOS which cause hair loss and rogaine helps the hair loss. Vitamin E is also good for hair. Go to the hair section in the store there is black hair care products that help with growth they are vitamin based.Is there anyway to grow back a receding hairline even a little bit?
