You need a barrier whenever transepidermal water loss occurs. Which is always. Your botanical oils do the same.

For intercontinental travel, you’re going to be jetlagged as all get-out and you’re going to want to chill. The trick is: when you’re most jetlagged, that’s when you have to force yourself to clomp around. Because you can’t fall asleep when you’re walking around with the sun shining on your face.

I think this is the kind of thing that only heterosexual people would get worked up about. In same-sex relationships, it's much more common for everyone to have clear and stated preferences about how they like to bone: there's no default assumption that there are some forms of sex that everyone is, by default,…

Netflix has it in some countries; google which countries. Use Hola unblocker (browser extension) to watch it, and use Adblock Plus to block Hola's ads.

Also, even white vinegar might be harsh if you leave it in, but if you rinse it out, I doubt it'll do damage. Acids makes the hair cuticle lower, making hair a bit smoother and less porous, and so hair will have more slip and look more shiny, less prone to frizz.

Another factor: the middle of the country doesn't have as much of a pedestrian culture — there's limited public transportation, the cities are more spread out because they're built for drivers, there are fewer places within walking distance, and the temperatures are more extreme (less comfortable to walk in the height…

High five to that.

Let's break this down:

then it doesn't matter in the slightest that sulfates remove oils since you're gonna have to apply those oils anyway as part of your hair care routine.

I'm actually not talking about rate of oil production. It doesn't matter how fast your scalp produces oil if you shampoo it all off. If your hair is longer than four or so inches, your scalp oils are never going to reach your ends. Unless you manipulate the hell out of it. Or stop shampooing it even with weaker…

I'm trying to make a slightly different point: that oils can have important protective properties for hair, and so it's reasonable to prefer not to use surfactants that are too effective at removing oil from your hair. I'm not trying to say that sebum is best. (With skincare, for example, many other oils are less…

Yeah, I should mention one of the reasons I'm being so preachy about this: I'm generally into DIY hair- and skincare, and recently I followed a touted recipe for DIY vitamin C serum. For a week or so, it was great, and then suddenly — it burned my damn face! A week later, my skin still stings. What happened? I…

Quick extra link to actual research down the citation chain from the previous links:

If it works for you, it works for you. But like I said, a spoon of baking soda in two cups of water has a pH of 9.9. Obviously the pH depends on the concentration. To get down to 9, you'd need at least 20 cups of water. And that's still bad for hair. All hair is different, and if this works for you, and your hair is…

Hair bleach is pH adjusted. Household bleach will dissolve your hair in one sitting. Hair bleaches are adjusted to a pH between 8 and 10. And again, baking soda has a pH of 9.9. You're talking about doing something as harsh as harsher-than-average bleaching to your hair every two weeks. If it's worth it to you, by all…

I think she's missing the point.

Repeating myself from below: Baking soda is also a strong alkali, and retains a pH of 9.9 if you dissolve a teaspoon in 4 cups of water. That pH is high enough that it can, over time, literally dissolve your hair. You might want to reconsider putting baking soda anywhere near your body.

This is wonderful. I compulsively pull hairs from all over my body — eyelashes, happy trail, outsides of my ankles, backs of my thighs (bonus: made me more flexible for yoga...), etc, etc. Luckily managed to stop scratching my scalp and tugging my eyelashes.

Rad, thanks!
