Question: are 2 in 1 shampoos any good?
Answer: Just stick to separate shampoo and conditioner products. ... A conditioner's purpose, then, is to remoisturize the hair and close those opened-up cuticles, giving hair a shiny and healthy look. The problem with 2-in-1 is that "a single product cannot open and close the cuticle at the same time," Davies said.
