Exactly WHAT growth aid are you applying?
Some people say that whenever their scalp itches, they always notice more growth than when it's not.However, without knowing the ingredients (and your own sensitivities) it is hard to say. Is it more of a tingle than an itch? Some products are designed to give that effect so you can "feel it working". Could the product be contaminated?Also, I know a lot of these growth treatments seem to contain sulfur. A LOT of people are sensitive to this ingredient. I know a woman who used it for a skin complaint and she was in the hospital seriously ill for several weeks. A lot of sensitivities can start out with a very mild reaction that can get extremely serious with repeated exposure, so you should probably check the ingredients and see if there is anything in there you are allergic to.
