Final answer:
The two types of shaves in a standard shave service are the lather shave with a soap-based cream that is lathered up with a brush, and the latherless shave that uses a brushless, non-lathering cream.
Step-by-step explanation:
The two types of shaves performed in a standard shave service are the lather shave and the latherless shave. The lather shave involves using a shaving cream that contains soaps and a humectant, which is worked into a lather with a shaving brush.
This type of cream helps to moisturize the skin and soften the hair for a closer shave. The latherless shave, also known as brushless shave, uses a shaving cream that typically doesn't contain soap and doesn't produce lather, but is instead an oil-in-water emulsion that can be applied directly to the skin without the need for a brush.
