I had very long hair for many years in my late teens. I had shaved in past and was not alien to it. However after a Mohawk I shaved it off for a job and then it was realised my front would never grow as thick to gain a mohawk of respect again. I had been window's peaking much like yourself for years and it was not until the front thinned I went bald.
I alway have been bald since and the only thing I must say is buy hats! Not to cover your baldness but to protect your head from the sun, even in winter you can get it sunburnt.
