So, I'm not sure what has happened but my hair is thicker and fuller these days than the past two years - quite possibly due to a reduction of stress.
But, I use Suave because many years ago, they had great commercials, which made sense. However, I do mix it up and use a yummy spicy shampoo from Sephora and one of those Paul Mitchell's, too. Not a lot of conditioner, but use Chi to calm the natural curl and wave.
P.S. I really like the shampoo at the Ritz. Not sure what it is, but I'll bet someone at Corporate would share that secret.
