I have very sensitive skin and in autumn, my skin always has eczema. I have tried this for two weeks and so far it is not causing any problem to my skin. It is very mild and the hair is smooth after using.I also like the conditioner. No need to use too much.The sales also advised me to use a little bit of their olive oil to apply to the split ends. Very good result. I'll try their suggestion of hot oil treatment when it get drier in winter.
