What?!
This is going to sound weird, but I went to cosmetology school many moons ago. We would use cholesterol on really dried out hair for deep conditioning. You can find it in the Women of color section at Walmart. Leave it on for a long time. Like at least a half hour, cover you head with a shower cap. It will help. You will at least get rid of that straw feeling.
Or a jar of mayo from the condiment isle in the grocery store
