RESUMEN
INTRODUCTION: Microneedling procedures are growing in popularity for a wide variety of skin conditions. This paper comprehensively reviews the medical literature regarding skin needling efficacy and safety in all skin types and in multiple dermatologic conditions.
METHODS: A PubMed literature search was conducted in all languages without restriction and bibliographies of relevant articles reviewed. Search terms included: "microneedling," "percutaneous collagen induction," "needling," "skin needling," and "dermaroller."
RESULTS: Microneedling is most commonly used for acne scars and cosmetic rejuvenation, however, treatment benefit has also been seen in varicella scars, burn scars, keloids, acne, alopecia, and periorbital melanosis, and has improved flap and graft survival, and enhanced transdermal delivery of topical products. Side effects were mild and self-limited, with few reports of post-inflammatory hyperpigmentation, and isolated reports of tram tracking, facial allergic granuloma, and systemic hypersensitivity.
DISCUSS: Microneedling represents a safe, cost-effective, and efficacious treatment option for a variety of dermatologic conditions in all skin types. More double-blinded, randomized, controlled trials are required to make more definitive conclusions.

As an alternative to hair transplantation for lowering the overly high hairline, hairline-lowering/forehead-reduction surgery has several advantages, including unsurpassed density and immediate results. Appropriate candidates for this surgery must have a stable frontal hairline (thus excluding most men) and a fairly to very mobile scalp that will permit sufficient advancement to warrant this more "invasive" approach. The main objective of this surgery is the lowering of the hairline. The authors' surgical approach, which was developed over the performance of more than 90 of these procedures and produces consistent results with low rates of complications, is described.

Hair transplantation, or hair restoration surgery (HRS) remains the only method to consistently restore hair in those experiencing pattern hair loss as well as hair loss from most other causes. HRS has been significantly improved with the development of follicular unit extraction, later renamed follicular unit excision, or FUE. This allows the surgeon to harvest grafts from the donor area without leaving a scar. FUE can also be used to harvest grafts from other areas of the body. When performed properly using the most technically advanced devices, the transection of the grafts with FUE remains under 4%.

The current state of the applicability of cell therapy for the treatment of various conditions of hair loss reveals a promising and potentially effective role. Further research, based on published work to date, is indicated to further explore the potential roles of autologous fat grafting, mesenchymal stem cells, and stromal vascular fraction therapy. The authors' evolving experience matches these promising scientific findings.
