Garnier Fructis Color Shield Shampoo and Biolage Color Last Shampoo…

The ingredients listing for these two shampoos are almost Exactly the same…. so… my question  is, are there different grades of the ingredients? More concentrated levels of one ingredient in one product vs another?? Why are the formulas so similar? I know they are both owned by L’Oreal, but could there actually be a difference between the two?

Thanks!!
