Different type of keywords for SEO

Hi there,

Maybe it is going to sound a bit "noobish", but just in case, I want to take an advice from you guys.

I have about 5-6 targeting keywords for the website. 3 of them belongs to one category and rest belongs to another category.
To make it more clarified, 3 of them related with shampoo (different types of it) and others are related hair-dye, hair formation and so on.
Could you help me out, how SEO should look from this perspective? I'm going to write a content related with shampoo and its products on homepage and for hair stuff I'm going to create an inner page and write a content there. Is it a right way doing that? I mean, will these different keywords are going in an appropriate way?

Thanks in advance for your replies.

I would not put either of them at homepage. Would make homepage just an introductory static page and put everything else lower to inner pages. It depends on your style, there's rarely right or wrong if you are making a site about one niche.

Rocket science is much easier.
