Shampoo badly dries out the hair. It's gotten so bad for me that I no longer use Shampoo. I use straight olive oil soap (which doesn't itch and doesn't dry out the hair - a trick the people from the middle east use) and I also use Castille Soap which comes in tea tree, natural, rose and almond scents. I switch between the two to stop the hair from getting used to one or the other. Tee Tree Castille soap also stops dandruff. However, without the problems dandruff shampoo causes.
Yay! no more dandruff, no more itching. I can't use dandruff shampoo because every brand makes my hair clump together so badly I can't comb it. My dad has always used dandruff shampoo - and now I suspect that he has the same problem I have. Shampoo is just too harsh. Even the organic shampoos without Laurel Sulfate gave me the same problem.
I also noticed that shampoo would cause my hair to break. I always found my hair all over the house - my husband would even comment on it! I also no longer have that problem even though I blow dry it with a brush after my shower.
My hair looks the same as when I used the other stuff. I don't really see much of a difference as to how my hair looked when I used shampoo. The GREAT difference is no more dandruff and no more infernal itching.
