[Kahlua]

I've read many threads and there seems to be controversy over whether to use strictly dog shampoos or if it is okay to use human shampoo. Can anyone tell me if they used some of the products that we use or if they have heard reviews on them. Kahlua has silky hair and we have used at least one bath a week since he was a puppy:
Johnson's Baby Shampoo on his face
Pet Gold Dark Coat Shampoo and Conditioner on his body
Neutrogena Clean Replenishing Moisturizing Conditioner

and as a moisturizer and spray between baths we have used:

Premium Groomer's Cologne with Aloe Vera for Conditioning Coat and Skin

I am just concerned because his body is no where's near as silkiy as the hair on his face, but its not seriously dry either. I want to try and save his fur if we are ruining it. I was curious if it was because of the Pet Gold dog shampoo that I use on his body or the neutrogena conditioner.

Any other recommendations and where I can find them will be a big help. We want our baby to be as handsome as possible.
