Review: Excellent product - This product does exactly what it says it does. My hair feels clean and very soft as the conditioner and mixed with the shampoo is a perfect blend. The smell is nice as well, but I am most happy with the way that it leaves my hair looking and feeling. After using this product, I don’t have to wash my hair for a couple days and it still looks and feels nice instead of extremely oily and dirty, like it did before I used this product
Review: Cleans well, rinses out easily, smells great, another excellent Jack Black product - I'm a Jack Black fan. They make useful, high performing products that i really love. This product is both a shampoo and conditioner. Many other shampoos I have tried have both but they do not rinse out well plus they leave an oily residue on my shoulders and back. This shampoo cleans well, conditions my hair so that it has a soft feel without being oily and rinses out better than any 2 in 1 shampoo / conditioner I have tried. Jack Black products are personal favorites - I have a lot and use them all the time. This will be my go-to shampoo as long as I still have hair. Recommended
