After about a year of my hair changing from curly and bouncy when using my favourite Trepadora gel to going limp, straight, dull and awful within a few hours, I think I’ve finally worked out that glycerin is the problem.
Apparently as a humectant, glycerin can pull moisture out of your hair if the air is drier than your hair, or pull moisture in if the other way around.
Think this started being a problem since I’ve been getting my hair coloured - guess the colouring has changed my hair in some way (although it’s quite gentle, no bleach).
Anyway, the Trepadora gel was bloody brilliant and still makes my hair super tight and curly but like I say, the problem is it all drops quickly and goes really dry-looking now, as I guess the humectant affects my now-coloured hair. I don’t quite get that super definition and volume with the glycerin free gel I use - if I layered my glycerin free gel over the top of the Trepadora would that seal it in and stop the humectant effect? Or should the glycerin-free gel go on first as a “barrier” for my hair?
