Glycerin

Glycerin is a colorless, thick liquid which absorbs water from the air and comes from a animal or vegetable fats. Because it attracts moisture to the hair and skin it is found in most hair and skin care products. Why is glycerin so important? It helps feed our curls the moisture it so deserves. Glycerin helps reduce frizz and provides flexibility to the curls.
Use glycerin in shampoos to add moisture to them, you can also use it in a spray bottle with water as the other component.
I recently bought Africare 100% Glycerin. I used it before I washed my hair, in conjunction with lavender water in a spray bottle, my hair was really soft, it still is. You don't need to throw away the products that didn't work for you (as long as they don't have petroleum/mineral oil in them) you can add a bit of glycerin and see if it works for you then. Try it!
