In this study, it was observed that NIPAL4 mutations linked to autosomal recessive congenital ichthyosis lead to abnormal skin barrier function due to cytotoxic effects disrupting lipid structure and organization, which topical treatments only partially ameliorated.

In this study, researchers demonstrated that follicular tight junctions in porcine skin form a barrier to nanoparticle penetration, particularly in upper regions, which supports its use as a model for human skin.

This article discusses the role of cosmetic hair care products in hair loss and concludes they do not cause it, suggesting a need for clinicians to understand the hair cycle and cosmetic practices for accurate diagnosis.

This study found that both everyday physical and environmental stresses, as well as chemical treatments, contributed to hair damage, with cuticle layers being more noticeably affected.

In this study, fiber implantation for pattern baldness was deemed ineffective and resulted in complications such as infection, scarring, and permanent hair loss, making it an unacceptable treatment option.

In this systematic review, oral minoxidil was found to be a safe and effective treatment for androgenetic alopecia and alopecia areata, with additional benefits for female pattern hair loss and other types of alopecia, although common side effects included hypertrichosis and postural hypotension.

This study highlights the significance of the hf pathway for the skin permeation of ionized and hydrophilic high molecular compounds, and the usefulness of hf-plugging in evaluating their skin permeability.

This article discusses various options for camouflaging hair loss involving the scalp, eyebrows, and eyelashes, and reports no new clinical findings.

This study observed that combining hair dyeing with sodium hydroxide relaxers drastically increased protein loss in Caucasian virgin dark brown hair, while ammonium thioglycolate or guanidine hydroxide relaxers caused less damage.

This study found that finasteride microemulsions significantly increased skin permeability in vitro, highlighting the potential for enhanced delivery of this drug through the skin.

This study found that chemically modifying hair with 2-iminothiorane hydrochloride improved the permanence of hair setting without damaging the hair by increasing disulfide bonds.

This study investigated a liposomal hydrogel system for delivering minoxidil and tretinoin to treat androgenic alopecia, finding that the system enhanced skin permeation of minoxidil while retaining tretinoin on the skin and was non-irritating in animal tests, suggesting its potential effectiveness.

This review highlights recent advancements in using niosomes as nanocarriers for improved delivery and sustained release of active cosmetic compounds, discussing their properties, applications, and future potential in cosmetic chemistry.

In this study, frequent use of hair straighteners/relaxers and pressing products was associated with an increased risk of ovarian cancer, with potential variation in risk by tumor type noted for permanent hair dyes.

This study reported that alopecic lesions after radiation exposure during angioembolization share dermoscopic features with alopecia areata, highlighting the importance of accurate patient history to avoid misdiagnosis.

This study found that a transdermal delivery system using 3% azone and P407 gel may enhance the skin permeation of doxazosin and finasteride for treating benign prostatic hyperplasia.

This study reports that keratin actives may protect various hair types from chemical damage, restore damaged fibers' mechanical strength, and reduce color fading.

This study found that controlled thermal straightening can achieve irreversible smoothing of curly hair without chemicals, with effectiveness dependent on temperature and cycles, and silicone enhancing straightening quality.

This study found that hydrolyzed wheat proteins extensively penetrated both untreated and chemically treated hair, primarily occupying areas like the endocuticle and cortex.

This study found that keratin film from human hair samples responded to damage from UV, bleaching, perming, and thermal treatments, making it a useful model for evaluating hair damage in product development.

This review discusses the dermatologic issues faced by transgender patients, including impacts of hormonal therapy on skin, but reports no new clinical findings.

This article describes a rare case of mixed black and white piedra in a patient's scalp hair, which is unusual as these two types of piedra rarely occur together.

This review discusses advancements in understanding the biology and pathology of the epidermis and hair follicles, reporting no new clinical results but highlighting the synergy between research and dermatologic patient care.

This study discusses that permanent hair straightening can be achieved at neutral or acidic pH conditions, with varying effects on cystine and lanthionine levels, by inducing supercontraction of the hair fiber.

Cold waving solutions quickly reduce cystine to cysteine in hair.

This article discusses dissecting cellulitis of the scalp, an uncommon hair condition, and reports no new clinical results; recent terminology adjustments are noted for potential overlaps with other follicular diseases.

This study reviewed the effectiveness of long pulse 1,064-nm Nd:YAG laser treatments for leg veins, hair removal, and skin rejuvenation, highlighting its safety, particularly for darker skin types, due to reduced pigmentary side effect risks.

This case study reports the first instance of irreversible alopecia universalis occurring during pegylated interferon-ribavirin therapy in a man with hepatitis C infection, without evidence of immunological or thyroid disorders.

This study found that perming and bleaching hair result in different distributions of cysteic acid, suggesting distinct damage mechanisms between the two treatments.

This case report describes postoperative alopecia in a female patient following orthognathic surgery and underscores the importance of understanding the condition's pathophysiology for prevention and identification.
