Haven't had much to report until now.
Polysorbate 80 has been a Godsend for me. I fully expect some one-size fits all shill to come in here and shout this stuff down, but I can't even begin to express how much better my hair/scalp quality are now - especially the diffused region up top. That area to me was the most embarrassing and made it such a pain in the *** to style every day.
Not anymore though. I'm about a month in and all I can say is I wish I had stumbled upon this stuff much sooner. Even the painful scalp acne on the back of my head is nowhere to be found. I'm not experiencing any regrowth at the moment, but this has silenced the shedding and diffused, whispy lifeless texture that used to be my hair. It's to the point where after I style it (which takes me half the time now) I can actually stand under the fog lighting in my bathroom and not be freaked out - especially in the area near my right temple.
Again - this has not regrown anything to this point, but I'm fine with that. For any of you diffused thinners, I highly suggest you get your hands on some. It's extremely cheap. Since it's an emulsifier and surfactant you must apply it with water. I typically wet my hair in the shower then massage the stuff in for 2-3 minutes, then leave it in for a couple more before shampooing it out.
I can't even imagine the nastiness that had accumulated in my scalp the last 10-12 years. I gave up chemical hair straighteners around 3-4 years ago, but have always relied on heavy doses of hair spray and other styling agents. Those along with the oily, excess sebum was not healthy. The first time I used P80, you should've seen the white foamy substance coming up out of my pores. There was an initial shed that almost scared me away from using it again, but I went back to it and it's been a serious improvement. I cannot say enough. I need to update this thread with pics soon.
