Has anyone ever added glycerin(either on its own, in conditioner or homemade products) to their hair? The shampoo and conditioner I use are great but they don't contain glycerin whereas the other products I used before did. I'm starting to get some frizz now because of it so I would like to know if it would work just as well if I add it to my conditioner or FSG?

I know that products like Curl Keeper contains glycerin but it's too pricy for my liking.

Thanks. 😌
