Is tea tree oil shampoo safe for all types of scalp?

I have been changing shampoos very often. When new products arrive, I try on them but as I have noticed, they are only effective when they are new in the market and after a month, it seems that they don't give same effects like they used to at first.
What is my guarantee that your product is safe, effective and will last for a longer time?
