This study compared the effects of direct heat perms and softening heat perms on hair, analyzing damage and morphological changes to understand their impact on hair fibers and provide foundational data for future research.

Environmental, chemical, mechanical, and personal health factors can all damage hair and contribute to hair loss or changes in hair quality.

In this study, researchers developed a non-invasive method to distinguish exogen hair from telogen hair on the human scalp, finding that normal exogen hair levels are generally less than seven hairs per cm².

The document explains hair growth, hair loss types, and other hair-related terms.

This study found that trichoscopic features like exclamation mark hairs and angulated hairs were more indicative of alopecia areata in an Asian population, while features like broken hairs of different lengths and flame hairs were more common in trichotillomania.

This study reports that military hair-grooming standards have evolved to support inclusivity by addressing racial diversity in hair and skin types, aiming to eliminate the adverse effects of tight hairstyles and reduce racial and gender bias.

This article reviews the use of dermoscopy as a noninvasive tool for diagnosing various types of nonscarring alopecia but presents no new clinical findings.

Hair shaft disorders often indicate genetic or systemic issues and are managed by minimizing damage.

This paper reviews hair structure and damage from grooming and cosmetic exposure but reports no new clinical findings; it suggests collaboration between dermatologists and cosmetic chemists to improve hair care products.

This study estimates that young adults have about 230,000 tactile afferent fibers innervating their skin, with density varying by region and decreasing with age.

This study found that intact pilosebaceous units were more effective than truncated hair follicles at regenerating a multilayered epidermis in a de-epidermalized dermis in vitro.

This article discusses the challenges in differentiating between basaloid follicular hamartoma and infundibulocytic basal cell carcinoma, highlighting the need for clarity in diagnosis but reports no new results.

This abstract introduces 3D bioprinted skin grafts as a promising alternative to traditional skin grafts, emphasizing how using stem cells in the bioink can enhance vascularization and hair follicle regeneration, potentially improving graft integration and function without the donor site risks.

This report describes two siblings with a new familial association of loose anagen syndrome and ocular coloboma, despite unaffected parents and no family history.

The author reports that using Total Excision Techniques in hair transplant surgeries increased graft yield by at least 50%, with minimal scarring in the donor area.

The new system makes hair transplants faster and more precise.

Various techniques and tools for hair restoration were presented in 1998, including a mathematical model for donor area, use of lasers in surgery, methods for controlling grafted hair direction, and ways to increase graft yield. Satisfaction rates were around 39%, and studies showed trauma and dehydration can damage hair follicles.

EFBL offers hidden incisions, faster recovery, and fewer risks, but may raise hairline and cost more.

This article reviews the classification of hair shaft abnormalities, outlining their diagnostic features, but does not present new research findings.

Trichoscopy is a useful non-invasive method for diagnosing different hair loss conditions.

This review summarizes the dermoscopic structures associated with infectious and inflammatory skin conditions and hair disorders in children but reports no new clinical results.

This review considers oxidative stress effects on hair aging and emphasizes the need for dermatologists to recognize and treat factors affecting scalp and hair health, but it provides no new clinical findings.

This article discusses the complexities of treating hair and scalp disorders in African American patients, emphasizing the importance of understanding their specific hair care practices and the unique impact on quality of life, but reports no new empirical findings.

This article discusses the use of cosmetic hair care products to improve patient satisfaction in hair loss treatment and reports no new clinical results; the authors emphasize complementing medical interventions with such products.

This review discusses the diagnostic and treatment challenges of trichotillomania and emphasizes the need for better-designed studies to optimize treatment approaches.

This study suggests that trichoscopy with a handheld dermatoscope may help differentiate temporal triangular alopecia from other localized alopecia by identifying specific hair features.

In this study, researchers identified three molecules in hair that varied with age, suggesting potential markers for aging and targets for cosmetic products.

This article reviews haircare practices and hair cosmetics for patients with alopecia, emphasizing healthy scalp maintenance and caution in styling; it reports no new clinical results.

This study found that keratin derivatives with functionalized thiol groups improved binding to both natural and bleached hair fibers, suggesting a promising strategy for enhancing keratin's durability in hair repair.

This paper reviews different types of hair shaft dysplasias and does not report any new clinical findings.
