Me, I've gone in the complete opposite direction sort of gradually, and, now and relatively recently could myself be described as non-moisturing wacko.
I've advanced past the stage of old broad to older woman to full out old person. I've flipped on all this..
After years of mad hair washing with all that entails re products, and if not mad, some considered skin moisturizing, I read articles advising the opposite. First I tried to learn to make my own shampoo, yada yada, and similar with moisturizers, after at least two, or was it three, as I moved, good dermatologists recommended less of this stuff.
So, one sunny day, I stopped. I now wash my hair not every couple of days, but about every ten days and only using a deluge of hot water. I take it this is better re maintaining natural oils. (Of course, this may relate to age and you guys are young, and out there sweating in the California sun, so, I dunno.) But, my hair has never been better. Ok, maybe when I was twelve.
I don't play sports at all now, so cleaning up isn't hard, but I'm spare with where I soap, based on the same principle of hot water and natural oils. My last Dermatologist agreed with me. Also, I've not had itchy skin for a couple of years.
Hope I haven't grossed you guys out..
