This is only really beneficial for certain types of hair, and definitely don’t do it with conditioners containing sulfates, parafinss, or silicones. This site has a comprehensive list of products that aren’t filled with garbage what’ll leave your hair drier than it started.
If your hair is neither thick nor fine and you’re not having any problems with buildup or dryness, you’re totally fine to just keep doing what you’re doing. Also if you’ve got straight and/or short hair you can probably ignore the no-sulfates/silicones stuff.
Most hair care products are designed for a specific kind of hair, usually straight and pretty flat. I started using black hair care products and my hair went from wavy and frizzy to natural ringlets and only sorta frizzy! SheaMoisture is my personal favorite brand.
