I've just paid a lot of money to have my hair coloured (balayage with some foils, looks very natural but brightens up my whole look).
The stylist tried to convince me that I NEED to purchase their very expensive shampoo and conditioner and that if I didn't the colour would go brassy very soon. I have a knee jerk reaction to hard sell so I said no and was a bit frosty with her.
I haven't washed it yet- now I'm worried it really will go brassy! She said any cheap supermarket products all have the same ingredient in them that I need to avoid.
Is this true? Did I need to buy a better quality shampoo, and can you recommend one? Preferably something with natural ingredients.
