Not for me, at all, for reasons, described above. And to tell the Truth, I suspected it: the one INGREDIENT both shampoo and conditioner have is MINT OIL, which I do not tolerate.
Also, it could be, Tea Tree Oil, was very toxic for me, too. When I was washing my hair today, I accidentally swallowed a bit of the shampoo water, and started coughing. Beware ! After using shampoo and conditioner for the first time today, the dandruff is just "flying" to my sweater: which had never-ever happened before !
My throat is still sore. I am switching back to Head & Shoulders, even though I love my other "normal" Nature's Gate Shampoos.
Bottom line: we all are different, have different needs and have different issues, at different phases in our lives.
Bottom Line No, I would not recommend this to a friend
