I found a set that included the shampoo, refill, and hair comb at my local drugstore, so I bought it. (I have a ReFa brush, so I didn't use the comb at home... but I save it for travel and baths.) Having both shampoo and conditioner in one is so convenient! It's a lifesaver, especially in the cold winter washroom! I was thrilled, but my family didn't seem to like it very much (they like to lather up properly before washing). I didn't experience any sticky feeling after washing, though. If I had to describe the texture, it's probably closest to a hair mask. Massage it into your hair from scalp to ends, comb it out, leave it for a bit if you like (you can wash your body in the meantime), and then rinse. Since the texture is heavy, I know the lid opens wide and comes with a scooping spatula, which is convenient, lol. After washing, my hair felt moisturized, probably because it's a moisturizing type. I didn't experience any skin irritation or other issues.
