This article describes cases of unusual scalp whorl patterns, including triple parietal and right temporal whorls, that were associated with normal development, and discusses theories of hair whorl development.

This narrative review from the authors discusses mechanical scalp stimulation as a potential treatment for androgenetic alopecia, suggesting it has a biologically plausible mechanism but immature clinical evidence; marketing of these devices currently outpaces their supporting data, indicating a need for better-controlled trials.

This narrative review suggests that while mechanical scalp stimulation has a plausible mechanism for aiding androgenetic alopecia, its clinical evidence is insufficient, and the marketing of stimulation devices currently outpaces their efficacy data.

This review re-examines hair blowouts as a material science process, where water acts as a plasticizer altering keratin's glass-transition temperature, allowing for temporary hair shaping through a moisture-induced matrix state change under heat and tension.

This article proposes several potential approaches for scar prevention and therapy, including anti-transforming growth factor-β strategies and tissue-engineered skin, but reports no new clinical results.

Ethanol spreads well on hair at low humidity but less so at higher humidity due to water condensation.

In this study, a mechanical model was developed to describe and validate the effectiveness of overnight hair curling, suggesting that combining it with hair fixatives can maintain a desired curl for over a day.

This review discusses the effects of vacuum massage on skin structures and concludes that there is insufficient evidence for its efficacy in treating burn scars, suggesting more research is needed on its potential benefits and mechanisms.

This study found that 3D microtissue models of dermal papilla cells can enhance the ability to induce hair-follicle neogenesis in vivo, offering potential for controlled cell production in follicle regeneration.

This case series reports successful treatment of refractory folliculitis decalvans using surgical excision with second-intention healing and guarded high-tension suturing, resulting in long-term remission without recurrence over a 10–24 month follow-up period.

In this study, wound closure tension following strip surgery for hair restoration varied by strip width, highlighting the importance of minimizing tension to achieve better scarring outcomes.

Best hair transplant results happen when tissues are least damaged.

This study observed that using a relaxed suture technique on scalp incisions may prevent linear scars by reducing pressure on upper stem cells.

This study reports that the mechanical interactions between human skin and adjacent subcutaneous white adipose tissue influence the appearance of skin wrinkles, with sWAT reinforcement potentially more effective for reducing signs of skin aging than skin reinforcement alone.

This article discusses the minimal research on hair growth physiology and highlights Dr. Masumi Inaba's contributions to understanding androgenetic alopecia, but reports no new experimental results.

This study found that using deep plane fixation during scalp surgeries significantly reduced closure tension and allowed for increased tissue excision compared to standard techniques without fixation.

This study found that deep plane fixation in scalp surgeries allowed for tension-reduced wound closures and increased tissue excision compared to techniques without deep plane fixation.

This study reported that a new surgical technique resulted in minimal scars visible to the naked eye in most cases, suggesting a significant improvement over conventional closure techniques.

This article proposes two new categories of cicatricial alopecia—“unstable” and “stable”—and suggests surgical excision as preferred over hair transplantation, especially for unstable cases.

This study suggests that peri-incisional triamcinolone acetonide may subtly benefit wound edge apposition in low-tension scalp regions during hair restoration surgery, but shows no statistically significant overall effect.

This study highlights that stress and coping styles significantly influence the symptom severity of Indian women with PCOS, emphasizing a need for culturally appropriate interventions to improve quality of life.

This study found that women with PCOS exhibited higher levels of depression, tension induction, and impaired stress coping strategies compared to healthy controls, with these psychological issues correlating with hyperandrogenism but not with central obesity or insulin resistance.

This review discusses the role of fascial mobilization in wound healing and its potential implications for treating chronic skin wounds and scarring, but reports no new clinical results.

This article introduces a new theory on male pattern baldness, attributing it to scalp pressure affecting hair follicles, and suggests it could revolutionize understanding and treatment; no clinical results are presented.

In this study, extracts from Chenopodium quinoa, Glycine max, and Malpighia emarginata demonstrated stability, low toxicity, and effective cleaning potential as surfactants in shampoo formulations, showing performance similar to or better than commercial shampoos in terms of surface and interfacial tension and sebum removal.

This review highlights emerging evidence that biophysical and metabolic cues, such as oxygen levels and tissue mechanics, significantly influence skin stem cell behavior, which is crucial for developing advanced wound healing therapies beyond traditional infection and inflammation control.

The document concludes that understanding health requires considering evolutionary perspectives on reproductive fitness, and recognizing the complexity of factors like diet, testosterone, and sexual orientation.

This review discusses various theories of skin aging and the importance of using professional and at-home skincare solutions, but offers no new empirical findings.

This study suggests that mechanical stress may influence androgenic alopecia patterning through a stretch-induced and androgen-mediated mechanotransduction mechanism in dermal papilla cells.

This review explores theories on the evolution of hair from synapsid scales and glands, proposing mechanisms supported by comparative studies, but reports no new experimental findings.
