The Glycerin Myth for Natural Hair. Is it Safe in Cold Weather?

If you have been natural for a while, I am sure you have heard that glycerin is a seasonal product. Natural hair vloggers make a point to talk about how they use glycerin in the summer but avoid it in the winter.  The reason being that glycerin is a humectant that draws moisture from the air to itself (to the hair) in the humid months, but does the opposite and pulls moisture out from the hair and out to the air when the weather is colder and dry, thus making the hair dry.

Many are saying that the theory that glycerin dries hair in the winter is a falsehood. Instead, glycerin holds in the moisture it originally has and can't release any of it.

Personally, I don't like glycerin that much.  I've noticed that products heavy on the glycerin make my hair sticky, dry and mushy.

Nonetheless here's a video that explains it further.
