Is there any special shampoo/conditioner i should use on my hair extensions ?

i just got them a few days ago and i want to make sure i am not going to mess them up if i use certain shampoo/conditioner.





i have garnier fructis and it's the avocado and different nutrient's in them for your hair and it's the three minute leave in stuff for conditioner and i got the shampoo also, could i use this on my hair extensions or should i get something else?





and if i should what kind? and where can i get it?Is there any special shampoo/conditioner i should use on my hair extensions ?
