As a person with sensitivities and allergies to a myriad of ingredients and fragrances, I was so delighted to find the Ultra Sensitive Solid Conditioner and Shave Bar. My hair and scalp have been getting dryer due to age and medical treatment, but my hair is thin and baby fine, and most conditioners weigh it down too much. I decided to give this product a try, and I am glad that I did. I've long used shampoo bars and am used to using hair products in bar form, but this one took a little getting used to, as it does not suds or lather at all. Because it is a very light conditioner and a hard bar, it doesn't feel like there is a lot of product on your hands or in your hair. I massaged it into my hair nonetheless, and was very pleased--it moisturized without weighing down my hair, and left a softness and subtle shine behind that was very pleasing. I've only used it a few times, but look forward to seeing the long term benefits! I also love that the bar doesn't dissolve quickly, but looks like it will last a long time.
