Body Shop Rainforest Moisture is a conditioner often used by curlies as I said. Banana conditioner looks CG friendly, but you very rarely see that used so maybe it's not that great as a leave in - not sure I'd want to leave fruit puree in my hair!!
The oils that penetrate are rich in lauric acid (coconut, babassu, palm kernel) or oleic acid (olive, avocado, argan). Good luck with the DIY, it's fun!
2a-2c, medium texture, porous/ colour treated. Three years CG, growing out mechanical and chemical damage = breakage and very high porosity. Past armpit length heading for waist.
