Number one, you cannot make hair grow faster. It will grow at a set rate. Some people are born with hair that grows fast, and others not. Don't bother with miracle products. It's a waste of time.
Two- the general idea of getting your hair shiny and soft is moisture. Moisturizing shampoo and moisturizing conditioner. Once or twice a week, swap out for a deep conditioner.
As to what you want to use, you'll wanna do research based on your preferences. I got some of the Bath and Body Works moisturizing shampoo/conditioner during their semi annual sale one year. Omg, the stuff was absolutely amazing. I stocked up on it, I loved it so much.
Recently, I've run out, so I've given the Aussie moisturizing conditioner a try and it seems to do just as well. It also smells amazing.
Again, as to specific products, that's on you and what you're willing to spend. I dye my hair, so I have a little different regimen that I follow (post coloring, I use a after color treatment along with the shampoo/conditioner routine). I ended up just learning the basics as to what prevents dull/brittle/dry hair and tinkered around. I found that keeping it all moisture/moisture, and avoiding brands that tout "fruit oil" anything (dries out hair) it gave great results.
A really good place to go is Sally Beauty. Their ION line is really good and the people that work there know their stuff.
