Best shampoo and conditioner for frizzy hair?

Savannah

My hair isn’t really curly but it has some curls in it, mostly towards the back of my hair. When I brush it, it all puffs up. I think my hair is dry so I usually buy moisturizing shampoo and conditioner but I don’t really see any improvement. Any suggestions for products? I’ve been using this kind but it doesn’t help all that much because as soon as I brush it once it’s dry, it frizzes up again
