I switched from L’Oreal Excellence to L’Oreal Prefernce years ago because I could not stand the smell of the Excellence. This last batch of Preference that I just used now smells just as bad as the Excellence version so I wont be purchasing this anymore. I will need to look for something different that doesn’t smell this toxic. Even after rinsing it out and applying the conditioner. It still stinks in my hair and I can’ stand the smell.
