System and method for automated hairstyle processing and hair cutting device

A method of hairstyle processing comprising acts of:

• receiving, from a memory, a predefined hairstyle model including hair property representing values and body shape representing values;
• sampling, by a sampling device, an actual body shape portion, of a to be treated subject;
• detecting, by a configured processor, deviations between the actual body shape portion of the subject and a model body shape portion of the predefined hairstyle model, wherein the actual body shape portion of the subject and the model body shape portion include corresponding representing values for both a contour of a hair portion and a level of skin at the hair portion;
• and
• adapting, by the processor, a hair property model of the predefined hairstyle model to compensate for the actual body shape deviations when the deviations between the actual body shape portion and the model body shape portion exceed a predetermined threshold;
• wherein the act of adapting the hair property model involves the processor adjusting only portions of the hair property model wherein the deviations between the actual body shape portion and the model body shape portion exceed the predetermined threshold such that less than all the portions of the hair property model are adapted.
