I have had some success with using Virgin Coconut Oil (VCO) topically for hair fall. I was diagnosed with diffused Alopecia areata long ago when my hair loss started at around age 19. My hair loss has slowly progressed for nearly a decade. I usually have increased hair fall in the summer and my scalp is ALWAYS tender. So much so that adding a barette or pulling into a ponytail causes my scalp to hurt so bad it causes headaches. I've tried some EC recommended remedies during this approx 2 month bout of intense shedding.
ACV, BSM, Idoral have not helped. The one thing that has reduced my shedding is applying coconut oil topically. I saturated my scalp, let sit for a couple hours and then attempeted to wash it out. This stuff is not going to wash away easily as my daily rinsing with white vinegar(make hair gorgeous! ) has yet to displace the oil completely. The next day my shedding was GREATLY reduced and is still reduced 3 days later. The downside for me is that I DONT care for my hair texture or the appearance of my hair(greasy) after the VCO application. My scalp sensitivity is also up (sebum cause by the oil?). BUT for those without my AA issues, I recommend highly trying VCO externally for hair shedding.
