Hair extensions can cause hair loss and scalp damage, and these problems might be more common than people realize.

This narrative review outlines the biological costs of hair extensions, such as traction leading to hair loss and scalp issues, and suggests a prevention-focused model involving risk assessment, surveillance, and tiered therapies to minimize alopecia risk and maintain scalp health.

This study describes an adaptive hair extension method designed to improve comfort, durability, and aesthetics, based on analysis of hypothetical client profiles and their biomechanical tolerance.

This study operationalizes a four-step workflow for selecting donor hair for capsule extensions, translating surgical trichology insights into an extension-specific protocol to enhance natural hair optics and biomechanics, suitable for premium extension services.

Hair extensions can worsen scalp conditions and should be avoided in those with alopecia.

Proper training is crucial for safe and effective hair extensions.

Hair extensions help Black women express identity and cultural heritage.

This case report describes a 23-year-old African-American woman who suffered a small bowel obstruction after ingesting hair from a hair weave, highlighting a specific risk associated with trichophagia in Black hair care practices.

Different methods like wigs, extensions, and devices can help improve hair volume for thinning hair.

The researchers reported that using extenders during scalp reductions increased effectiveness by 30 to 86% and prevented "stretch-back" in subsequent procedures.

This literature review found a lack of scientific studies on whether apple cider vinegar rinses can reduce carcinogenic exposure from synthetic hair extensions, indicating a need for future research to explore this potential intervention.

This study on Alzheimer's patients found that chronic sodium selenate treatment (up to 23 months) was safe and well-tolerated, with most adverse events being mild, and suggested potential slowing of cognitive decline, though confirmation requires further controlled studies.

This article examines how digital technologies, drawing on Marshall McLuhan's concept of media as an "extension of man," transform design thinking by creating new possibilities without replacing it, emphasizing the need for a hybrid, reflective practice in design.

This study introduced and validated the VESALT, a visual extension of the Severity of Alopecia Tool, finding it offers improved reliability and user-friendliness over SALT by incorporating pattern recognition and broader coverage, including non-scalp regions, in assessing alopecia areata severity.

The pilot study found that while women with habitual short sleep increased their sleep duration by an average of 40.7 minutes, there were no significant changes in insulin sensitivity, androgens, or leptin levels post-intervention, suggesting further research is needed.

In this observational study of female undergraduate students, researchers found a significant correlation between the use of eyelash extensions and ocular side effects such as itching, lashes pulling out, and heavy eyelids, affecting 54% of participants during or after use.

This study found that in Arabidopsis thaliana, the interaction between extracellular leucine-rich repeat extensins and the receptor-like kinase FERONIA helps control vacuolar expansion, crucial for cellular elongation.

In this study, researchers identified a three-step process underlying age-related curved hair from cyclical extension: surface lipid transfer, specific disulfide bond cleavage, and unraveling of α-helices into β-structures, which may inform care strategies to manage hair curvature.

This study found that ritlecitinib was well tolerated in children aged 6 to under 12 years with severe alopecia areata, with ongoing trials examining its efficacy and safety over a 24-week period and in long-term use up to 36 months.

This study found that gene therapy using a mouse cytomegalovirus vector with telomerase reverse transcriptase or follistatin significantly extended lifespan and improved health markers in mice, without adverse effects.

This study concluded that teriflunomide has a consistent and manageable safety profile, with common mild-to-moderate adverse events and no new safety concerns identified over up to 12 years of treatment.

This case report describes the successful surgical removal of a trichobezoar in an 8-year-old girl, which extended from her stomach into the duodenum.

This study found that despite the persistence of aberrant double-negative T-cells, functional immune-competence was maintained after thymic transplantation in a patient with a rare FOXN1 mutation.

In this study, researchers identified three root hair-specific peroxidases that may control cell wall properties during root hair cell expansion, affecting growth, enzyme activity, and cell wall structure.

This study found that the oral JAK inhibitors ritlecitinib and brepocitinib were effective in maintaining hair regrowth in alopecia areata with continuous use, though efficacy decreased after withdrawal.

This study suggests that a proprietary nutraceutical supplement gummy and peptide serum regimen may be safe and effective for improving hair growth and density in females with pattern hair loss.

This review discusses various methods to conceal hair loss, such as wigs and hair transplants, and reports no new clinical results.

This study observed that while hair camouflage techniques can boost confidence and reduce stigma for Black women with alopecia, they can also contribute to further hair damage; clinicians should consider safer styling practices as part of individualized care strategies.
