Except for the density, that's exactly where I started when I first started to lurk on nc.com! My hair was dense when I was young. Age, thyroid and a medication I take have thinned it.
Products won't "harm" your hair. You'll just continue to be overconditioned--soft and frizzy. Not sure why you'd want that???
You need to add protein in order to correct it.
I use a lot of rich products, but conteract it with protein. I do at least one PT (with a moisturizing PT) a week and use a lot of products with protein. Never have to DT.
