With the long hair DLC came a different style palette for long hair designated clients. I would like to recommend (highly) the original palette there too, with all options. What is the point of long hair, if you can not cut it to a pixie? (okay you can, with tricks...) Also, some hairstyles are missing from the original palette. For example the classic bob, with shaved nape, which is cuttable for some costumers is missing. Also, a shaved option would be good, if it is a possibility.

The "cutting line" at specific styles, only a length reducer. Looks total procedural. It should be there at all styles. Maybe with some proper scale settings. No point for 3 useable positions, and all the others just bald. The actual style is the end of the slider, total bald is the other end. Steps are facultative, I prefer smooth slide options. Also, there is no effect moving the slide after apply, only if clicked to another style, and back.
