This chapter discusses the concepts of regeneration and homeostasis, noting that in vertebrates, regeneration is limited to certain tissues like liver, blood, and bone.

This study identified specific genetic variants as the cause of visual impairment and non-syndromic alopecia in two brothers, reinforcing the link between PDE6H variants and achromatopsia and LPAR6 variants and alopecia.

This study identified two distinct histological patterns in permanent alopecia following bone marrow transplantation, suggesting links to myeloablative chemotherapy and chronic graft-versus-host disease.

This study observed that alopecia areata can be induced and serially transferred in C3H/HeJ mice using skin grafts, providing a useful model for studying the disease in humans.

Low oxygen and metabolic changes help organoids grow and repair tissues.

This article reviews various models of graft-versus-host disease, highlighting the complexity of its mechanisms and the challenges in interpreting histopathologic data; it reports no new results.

This abstract contains no research results; it's a website navigation menu and institutional policy information from JAMA Ophthalmology.

This study highlights a case where progressive baldness initially diagnosed as alopecia universalis was attributed to a basal cell hamartoma of each hair follicle, stressing the importance of skin biopsies for unusual alopecia cases.

This study found that histopathologic features such as a catagen/telogen shift, melanin in fibrous tracts, and small dystrophic follicles can help differentiate alopecia areata from pattern hair loss in the absence of peribulbar infiltrates.

In this case study, a comprehensive reconstruction approach using autologous fat grafting, follicular unit excision hair transplantation, and scalp micropigmentation led to significant aesthetic and psychosocial improvements in a male patient with severe facial and scalp burn injuries.

In this case report, the authors observed that scalp injection of autologous adipose tissue had a positive effect on hair growth in a patient with trauma-related alopecia, suggesting it might be a promising treatment for alopecia.

This review discusses the authors' approach to reconstructing scalp and neurocranial defects and reports no new clinical results.

Unknown factors significantly affect hair growth in skin grafts.

In this case report, a 44-year-old woman underwent a successful hair transplantation using follicular unit extraction on a myocutaneous free flap, resulting in an 80 to 85% hair survival rate after 12 months and significant improvement in external alopecia aesthetics.

This study reported that partial longitudinal follicular unit transplantation improved eyebrow appearance and patient satisfaction without visible scarring, making it a reliable method for eyebrow restoration.

This case report describes a 27-year-old male who developed a frontal scalp hematoma after platelet-rich plasma therapy and suggests that topical minoxidil may contribute to this side effect.

In this guide, the authors describe a scalp incision technique that minimizes damage to hair follicles and results in barely noticeable scars in hair-bearing areas.

This report describes a 3-year-old boy with a potential new neurocutaneous syndrome characterized by unilateral alopecia, ipsilateral hemimegalencephaly, and intractable seizures.

This study found that hair transplantation for head and neck scar alopecia was targeted based on scar characteristics, with follicular unit extraction often preferred for less extensive graft needs.

This study in hairless rats suggests that the deletion of specific hair keratin genes contributes to hypotrichosis and highlights the strain's potential as a model for hair follicle research.

This study found that follicular unit transplantation is an effective and minimally invasive technique for camouflaging scarring alopecia in the head and neck area, achieving a graft survival rate of 86% and high patient satisfaction.

This study found that follicular unit extraction is effective for treating scar alopecia after craniotomy, with better outcomes achieved when 1-year postoperative hair density exceeds 20 follicles per cm².

This case report describes a 57-year-old man's severe complications, including acute stroke and scalp necrosis, following platelet-rich plasma and stem cell injections for hair restoration.

This study identified histologic lesions and a defect in adhesion molecules causing hair loss in mice with the bal mutation, linked to a mutation in the desmoglein 3 gene.

This study reports five cases of congenital triangular alopecia featuring a central island of short terminal hair, with the cause remaining unknown.

Refined open donor harvesting techniques can reduce hair follicle damage in hair restoration surgery.

This abstract is a navigation and policy notice for a website and does not contain any research findings.

This case study describes successful treatment of a left temporal scalp arteriovenous malformation through a multidisciplinary approach combining endovascular embolization and surgical excision, resulting in high patient satisfaction.

This article discusses the link between poor body positioning during graft dissection and reported injuries in medical hair restoration, but provides no new clinical results.

This article recounts the author's early experiences in attending a 2014 Brazilian hair restoration surgery conference and reports no new research findings.
