Etoposide - starting treatment tomorrow. Are there any hair care products or cleaning products I should avoid whilst I'm on this?

I'm starting Etoposide tomorrow. I had chemotherapy last year and I read a lot of information about the need to use natural products, and to be cautious when using cleaning products. I can't seem to find this information now. Obviously I'll be cautious, but are there any hair care products, or cleaning products I should avoid?
