It depends what there specially made for, if you have dandruff and you get a shampoo that says it will 'take away your dandruff forever' and it doesn't take your dandruff away then you'll know it didn't work. Or is it says it will 'make your hair smell amazing' and it doesn't then it didn't work! Basically if it doesn't do what it was supposed to do and what you wanted it to do then you'll know it hasn't worked. OKAY?
Yes.
You can use natural oils, or shampoos like the ones that have tea oils, I heard that tree tea oils in shampoos work fine.
Dry shampoos work by absorbing excess oil and dirt from the hair using powders like starch or clay. These powders help to break down and lift away the buildup, leaving the hair looking and feeling cleaner without the need for water.
Well, for each person, different shampoos work best. My opinion- (or recommendation) for a shampoo would be suave or panteen. *Try not to use Head and Shoulders-it makes hair fall like rain! Trust me!
Some of the Bumble and Bumble shampoos are organic. Most of the Bumble and Bumble shampoos are not organic. The shampoo is very good for your hair but not all are environmentally sound.

You should use sulfate-free shampoos on color treated hair.
My favorite clarifying shampoo that I always recommend to clients is Paul Mitchell's Shampoo 3.
There are many different shampoos that work well for long haired men. One shampoo that works best for one will not work the best for another though.
the shampoos do not contain appreciable amounts of acid, alkali, alcohol, or salts which would prompt irritation which causes tearing
yes they do if you have curly hair if you have straight then regulars do.
Unlike dogs, cats are naturally good groomers. There is no need to bathe them, hence no need for "cat shampoos."
