Why is Glycerin Bad for you in the Winter?
Hi I'm a longtime lurker coming out of hiding! lol. Some people say that vegetable glycerin will dry your hair out in the colder, less humid climates. However, based on a few articles I've read including one on CurlyNikki's blog, veg glycerin is actually still moisturizing when the weather is cooler and less humid. Here's a quote from the Curly Nikki Blog:

"Glycerin (glycerine/glycerol - all the same thing) is hygroscopic. This means it draws moisture (water) from its surrounding. It is very good at doing these because it has 3 water attracting groups (known as hydroxyl groups) per molecule (As far as molecules go, this is quite high!). This is the reason why some people say that glycerin is drying which is sort of true but not really. If you expose glycerin to air, it will saturate itself to the point where it does not need any more water. And when you put it in water (which it loves), then it will REALLY saturate itself and will not draw water away from your hair. Therefore, the message is glycerin plus water, is good! While the herbs and essences probably just make the product smell good, the glycerin is the stuff that makes it moisturising.
