Tea Tree Scalp Routine Set

I got this set for my wife who has sensitive skin. She lives the scrub and the shampoo, but strongly dislikes the conditioner. It has fragrance in it and it is pretty strong. I don't know why if the tea tree collection is supposed to be an antifungal and repairing product, why you would put fragrance in it. I would have thought it would have a mint type smell like the rest of the collection. Roycederm needs to make a mint scent or a no scent conditioner.
