Query: The odor is pretty awful! does hair texture matter?

I am an African American. Before purchasing this product I contacted the company and asked would it work in the same fashion for your 'typical' African American hair texture. (i.e., "kinky) and they said yes.I have used for OVER a month now and have NO significant change in hair color and the smell is God-awful!!!My girlfriend complained that she has a hard time with the smell also, so I know its not psychological.I am more dispapointed by the smell than i am about the effectiveness, because nothing is 100% foe everyone. the smell though is mentioned specifically in their ad as being odorless.Very unsatisfied customer.
