Glycerin, or glycerol, is a colourless or odourless sugar alcohol that is derived from plants and can also be produced synthetically. It can retain moisture from its surroundings and is a natural humectant that adds moisture to our skin and hair as well. Glycerine has a small molecular size, which allows it to work like a moisture magnet, eliminating dullness, dryness, and flakiness and improving the overall appearance of our strands. Let’s dig deeper to understand the benefits of applying glycerine to our scalp.
