Expensive shampoos and conditioners like Biologe any better than cheap ones?

Just curious if they are worth the extra money.. Also what shampoo and conditioner is good for damaged hair.Expensive shampoos and conditioners like Biologe any better than cheap ones?
It's definitely better than Suave.


Shampoo: Lush Rehab Shampoo


However, I'd buy cheap V05 Herbal Tea Conditioner; it makes your hair very silky.Expensive shampoos and conditioners like Biologe any better than cheap ones?
i just started using biolage smooth and i is amazing! yeah it is pretty expensive though so i only got the shampoo and not the conditioner. it works really well though. i use pantene conditioner
No, it depends on your hair. I use natural shampoos from whole foods. you should try them and see if it works for you.
