shampoo that doesn't stop working after a few washes

[stottiecake]

I have to constantly change my shampoo as after a few washes with the same shampoo my hair starts to feel lank and yuk. is there a solution to this? any miracle shampoo out there that I havent come across? thanks

I used Aussie Mega shampoo and conditioner this morning and my hair really does feel clean and soft. Will be interested to see how it is after using it for a few days.

I use wella SP clear scalp. Loads of the Pantene, L'Oreal, etc ones have silicone that builds up but I've not had that problem with any of the Wella ones. Although they are more expensive so I buy off the internet in bulk rather than £12 a bottle out the hairdresser.
