In this study, tissue expansion was identified as a safer initial procedure before hair transplantation for patients with large scalp defects, with the majority of participants having postburn scars and a mean expansion time of 33.6 days.

This study developed a method for expanding human dermal papilla cells in vitro while maintaining their ability to induce hair growth, advancing the potential for follicular cell implantation as a treatment for hair loss.

In a rat scalp expansion model, this study found that activating autophagy with rapamycin enhanced skin regeneration during tissue expansion by increasing expanded skin area, epidermis and dermis thicknesses, cell proliferation, angiogenesis, and other regenerative factors, whereas blocking autophagy reversed these effects.

This case report detailed a successful treatment involving contracture release and expanded neck flap reconstruction for a patient with severe neck contracture and beard alopecia from past thermal burns, highlighting improved skin quality and hair regrowth following follicular unit extraction.

This article discusses the use of scalp stretching techniques to enhance donor hair supply for hair restoration, but it reports no new clinical findings.

This text provides contact information and no new research findings are reported.

This review discusses the use of trichoscopy for diagnosing systemic diseases and concludes that certain trichoscopic features may help dermatologists suspect these conditions.

This study created a detailed spatial atlas of healthy human skin and basal cell carcinoma, revealing a potential hair follicle origin for basal cell carcinoma and expansion of certain mesenchymal cell populations.

This review discusses the various applications of platelet-rich plasma in dermatology, particularly its potential in esthetic dermatology and hair and scalp conditions, but reports no new clinical findings.

This study found that prolonged acute tissue expansion notably increased the amount of scalp tissue removed during scalp reduction surgery in three patients.

This study found that micrografts containing human hair follicle mesenchymal stem cells significantly increased hair count and density compared to placebo over 58 weeks in patients experiencing hair loss.

In this case study, a 35-year-old male with severe burn-related scalp injuries underwent successful reconstruction through tissue expansion, skin grafts, and multiple hair transplant sessions, resulting in satisfactory aesthetic and functional recovery.

This study reports that using a combined approach of free osteoseptocutaneous fibula flap and temporal artery-based scalp flap provided satisfactory aesthetic and functional outcomes in reconstructing gunshot-inflicted composite mandibular defects in males.

The authors concluded that using an expanded temporoparieto-occipital scalp flap for sideburn reconstruction provides satisfactory hair direction and inconspicuous scars in both the donor and recipient areas, with few complications.

This study suggests that newly developed micro-pigment-encapsulated biodegradable microneedles accurately implant pigments in pig cadaver skin, potentially advancing scalp micro-pigmentation methods.

This study found that local refinement of hair follicles into higher order patterns can occur without the core planar cell polarity system, but global alignment with body axes requires its function throughout development and regeneration.

This study evaluated surgical methods for treating cicatricial alopecia and found that factors such as size, location, and shape are crucial in deciding the approach, with good outcomes seen in 18 out of 24 patients.

This review discusses current techniques for scalp reconstruction following oncologic surgery and reports no new clinical outcomes, emphasizing the importance of tailored approaches for satisfactory closure.

Artificial dermis used for hair transplantation can reconstruct scalp defects effectively without the need for tissue expansion.

This study observed that platelet-rich gel for scalp defect reconstruction was more cost-effective and less painful but resulted in poorer hair growth compared to the external tissue expansion technique.

This article reviews various reconstructive surgery techniques for scalp wounds and emphasizes factors affecting aesthetic outcomes, but it presents no new clinical findings.

This article reviews techniques for repairing scalp deformities and concludes that combining older methods with modern hair restoration allows for satisfactory treatment of large scarred areas.

This article reviews surgical techniques for addressing scalp defects and highlights hair restoration as a cosmetic improvement strategy, but it reports no new clinical results.

This article reviews scalp advancement and forehead shortening when combined with a brow lift, focusing on reducing temporal recession, but reports no new clinical results.

This research review explores an algorithmic approach to scalp reconstruction, emphasizing the importance of considering defect location, size, and local scalp anatomy in optimizing cosmetic and functional surgical outcomes.

The researchers reported that follicular unit hair transplantation achieved a mean graft survival rate of 80.67% and significantly improved patient and observer satisfaction in individuals with stable cicatricial alopecia from postsurgical scalp scarring.

In this systematic review, the researchers provide an overview of recent techniques and innovations in the surgical reconstruction of traumatic scalp injuries, highlighting various methods and factors influencing the choice of reconstructive strategy to improve patient outcomes.

This study found that the patch assay effectively reconstituted mature hair follicles using culture-expanded human fetal cells and may serve as a method to assess cell trichogenicity.

This study concluded that early-stage tissue-engineered skin substitutes, developed using skin progenitor cells, had a better graft efficiency and supported hair follicle formation, which may improve wound healing outcomes.

This review discusses recent advances in surface modification and endothelialization of biomaterials for vascular grafts, highlighting promising methods like gene engineering and targeting ligand immobilization to improve clinical outcomes.
