Abstract: The present methods, systems, and kits permit the induction of multimodal injury to a subject's skin. This approach maximizes the responsiveness of the treated area to treatments for producing hair follicles; exciting, activating, and dispersing existing hair-producing structures; and bringing about other physiological changes that correspond to increased hair growth and/or the growth of more robust hairs. In contrast with conventional methodologies, the present methods and systems provide heretofore unattainable advantages through use of a multi-pronged approach of de novo hair follicle production, in combination with reorganization of existing structures to produce new follicular units, as well as pharmaceutical enhancement of both processes, and other gainful techniques.

Abstract: The present disclosure provides methods and systems for increasing hair growth in subjects in need thereof due to male- or female-pattern hair loss, pathological hair loss, or hair loss after injury. By any use of any appropriate mechanical, electromagnetic, or chemical means, the present disclosure pertains to the segmentation of hair follicles into two or more disunited subunits in order to form new follicles from the respective subunits. In contrast with known techniques for bisecting hair follicles and as described more fully herein, the present methods and systems permit the bisection of single follicles or populations of follicles with a high degree of efficiency, and thereby represent an effective treatment option for those in need of increased hair growth.

Abstract: The present methods and systems provide treatment of a preselected body surface by injuring a portion of the body surface, optionally applying a composition such as a pharmaceutical agent to the injured portion of the body surface, and selection of a further portion on the body surface for the same or different injury and optional contacting with the same or different composition, wherein the further portion has a preselected geometry with respect to the first injured portion. The repetition of the selection, injury, and optional exposure to a composition with respect to successive portions of the body surface, optionally under partial or total computer control, provides efficient treatment of the body surface pursuant to the objective of regeneration, remodeling, resurfacing, restoration, follicular neogenesis, neocollagenesis, stem cell recruitment, activation, or differentiation, reepitheliazation, wound healing, or any other desired biological or physical modification.

Abstract: The present methods and systems provide the induction of preselected injury types to target areas of tissue in an iterative manner in order to provide beneficial treatment with respect to a desired body surface. The methods and systems disclosed herein may include the precise selection of target areas for treatment, which may itself involve identifying physical features that require treatment, distinguishing areas or features that are not suitable for treatment, or both. The present modalities are distinguishable from prior methodologies having lower rates of success because of the failure of the latter to match treatment or treatment type with specific physical features.
