Out of interest, do most start on the normal one and progress up to the Extra strength version, of can you start straight away with extra strength, what do you guys recommend?
Also, do Boots or the like, in the UK offer the foam, or should I start with the liquid?
Please tell me what you guys recommend, normal or extra strength
Thanks
