Hi! I know some suitable products from iherb.com! Here are some:
Kinky Curly Knot Today: completely humectant free! Kinky-Curly, Knot Today, Natural Leave in / Detangler, 8 oz (236 ml) - iHerb.com
Kiss My Face gel: only one humectant (pathenol!) and very low in the list: Kiss My Face, OHC, Upper Management, Styling Gel, Grapefruit, 8 fl oz (236 ml) - iHerb.com
Not glycerin free, but not pure glycerin either, and low in the list:
Beauty Without Cruelty leave in: pathenol somewhere in the middle, and ethyl hexyl glycerin low in the list. I live in an area where the dewpoint is at least 70 right now and this leave in works for me: Beauty Without Cruelty, Leave-in Conditioner, 8.5 fl oz (250 ml) - iHerb.com
Andalou Naturals gel: almost the same as Beauty Without Cruelty when it comes to humectants, might work for you: Andalou Naturals, Styling Gel, Sunflower & Citrus, 6.8 fl oz (200 ml) - iHerb.com
Just keep in mind, the CJ Repair Me is a protein treatment and the Argan and Olive oil is a much lighter protein free conditioner.
