Giovanni has built its line around salon-style hair care, and Smooth As Silk is the collection most people meet first. The shampoo pours out pearlized and glossy, works up a full, cushiony lather from a small amount, and rinses out easily. The conditioner is thicker and creamier, with enough slip that a wide-tooth comb moves through wet hair. Both carry the same soft, faintly fruity scent that fades as hair dries rather than lingering all day.

This is the 24 oz pairing, the size most households settle on once a bottle has proved itself. Wet the hair, massage the shampoo through scalp and lengths, rinse, then work the conditioner from mid-shaft to ends and rinse again. Using the two together is how the line is meant to be used, and the larger bottles go a long way in a shared bathroom.
