Hi curlies!

I'm trying to get CG since yesterday.
Now today I went to the hairdresser (it was time to colour my hair) and he washed my hair with a shampoo and condish containing sulfates and silicones.
To get rid of those silicones: would it be ok to use a sulfate shampoo which is silicone-free and then continue by using things that are both sulfatefree and siliconfree?
Or what do you suggest?
