I ran out of my Aveda brilliant shampoo and was using a normal buy one get one free supermarket shampoo as bit skint. Ended up having to wash my hair more frequently and actually seemed to be buying more shampoo!! Gave in and brought another giant bottle of Aveda Brilliant (last one lasted 4 months)!! Didn't realise quite how lovely it is until started using it again!!! Just thought I would share!!! Even when dosh is scarce a good shampoo makes me feel a million dollars!!!! Ps there is some amazingly cheap deals online
