Shampoo and conditioner combined in one bottle for convenience for people with normal, healthy hair. There are essentially 2 ingredients that have been added to a regular shampoo to make it a 2-in-1 product: silicone and a suspending agent. Silicone makes the formula conditioning, while the suspending agent keeps the silicone from separating out of the formula while it is in the bottle. Once massaged in the hair, the silicone separates out from the rest of the formula and stays behind on hair to provide conditioning.
