@PeaceLoveNaturals if you’re referring to the DIY market, yes. I see oily concoctions everywhere!
In comercial products I see more cationic surfactants, PEG oils and silicones. Not much is needed of either or you’ll end up with heavy, greasy hair with a lot of build up if a strong shampoo is not used.
I don’t have experience making conditioner, so I’ll leave that up to the experts. But I think for fine hair the last thing you’d want is something heavy that takes away volume. That basically removes all oils and butters from the equation in my opinion. They’re too heavy. Maybe 1-2% total of “light” oils like Argan, Jojoba, Castor is fine. I have thinning hair and can’t even use a comercial conditioner because it exacerbates my hair loss, my hair becomes too heavy and looses all volume. I also have oily scalp, so the last thing I want is more oil on my hair products.
