I've been learning what my hair likes and doesn't like recently. I know my hair is not a big fan of glycerin or protein so I've tried buying products with out it but even those have not been working and that's what's really disheartening right now.
I've tried regular leave ins and those don't seem to really work for my and I've tried leaving a bit of conditioner in my hair after rinsing and that makes my hair feel even worse. My hair doesn't particularly like light, penetrating oils like coconut or olive so I just stick to heavier things like castor oil though my hair will end up feeling dry after about an hour. I do wet my hair as much as possible but once it dries, it feels like straw and is very wiry.
I always clarify when using a new product because the I can really see if it works or not. I also have been using protective styles since nothing seems to work for my hair. And yes, I know exactly what you mean about others holy grails. After experiencing so many fails with supposed "miracle" products I did more research to learn about what my hair liked and didn't like to avoid such terrible experiences again.
What is a hair analysis? I know my hair is low porosity, is very thick and is extremely coarse.
Right now the only decent product that I've been sticking to is Elasta QP Creme Conditioning Shampoo. As a leave-in and moisturizer I use QB Burdock Root Cream. It works ok but, it doesn't really leave my hair feeling moisturized for long (maybe 2 hours tops) I even mixed it with aloe juice because I know hair needs slightly acidic products to balance out it's pH. I seal with castor oil mostly because so far it seems to be the only sealant my hair tolerates. When I first started transitioning my hair was suffering from protein overload and someone recommended I use Aussie moist 3 minute deep conditioner. It left my hair feeling moist, soft and just great. When I tried using it again it made my hair feel dry and hard. I tried using a protein conditioner but that made it worse. So ever since then, I've yet to find something that leaves my hair feeling even half as good as the Aussie did that one time.
I use shea butter from time to time but it just doesn't leave my hair feeling moist for more then an hour at most.
Last night I bought Jessicurl WDT because it's protein and glycerin free. I put on a shower cap and left it on for a couple of hours and once I rinsed it out, my hair felt so dry and hard. I was really hoping it would work but it didn't and that's what really made me want to just quit. I'm considering trying KBB's Luscious Locks Hair Mask along with the Sweet Ambrosia (glycerin is pretty low on the list of ingredients). I'm still thinking about getting the Butter Love.
