The Detangler is such a classic product from Paul Mitchell that I even remember using this conditioner before and after my childhood swimming lessons! It is great for medium to coarse hair that has been chemically-treated. Which is what makes this product so great for swimming. Because not only does it heal damaged ends due to chemicals, but it also helps prevent damage from the sun and it's harmful UV rays. Apply this product before heading into a pool, and leave the chlorine and chemicals behind!
