In a non-blinded study with 12 Japanese participants, applying a lotion containing Lactiplantibacillus plantarum N793 to the scalp for 24 weeks significantly increased hair density and reduced hair loss, with participants reporting improvements in hair thickness and volume, and the treatment deemed safe.

This study concluded that there was clear evidence of carcinogenic activity of C.I. Acid Orange 3 in female F344/N rats but not in male rats or B6C3F1 mice of either sex.

In this study using a mouse model of Pemphigus vulgaris, researchers found that loss of desmoglein 3 adhesion in hair follicle stem cells triggers a regenerative program restoring stem cell function, requiring Hedgehog pathway suppression.

ANp63 is crucial for skin integrity, new filaggrin gene mutations link to eczema, hair can regrow from non-stem cells, sunburns are increasing, and glucocorticoids help treat skin allergies by affecting immune cells.

This research identified K31 as a new marker for distinguishing clear secretory cells in human eccrine sweat glands, aiding in differentiating between distinct cell types within these glands.

This study revealed that frizzled 3 can fully rescue polarity defects in frizzled 6-null mice, while frizzled 6 can partially rescue defects in frizzled 3-null mice, highlighting conserved signaling roles in these proteins.

Chemical treatments damage hair more than UV exposure, making it thinner and less flexible.

This study found that acid regulation of the TRPV3 channel can inhibit its function from outside the cell while facilitating it from inside, providing insights into skin barrier and disorder mechanisms related to tissue acidosis.

This study found that heterozygous mice overexpressing Claudin-6 experienced alterations in epidermal and hair follicle differentiation, leading to distinctive coat characteristics and a disrupted epidermal permeability barrier.

This study found that a spontaneous deletion in the Dsg3 gene of mice leads to hypomorphic desmoglein 3 expression, resulting in severe immunodeficiency, cyclic hair loss, and wasting disease, without causing the blistering typical of pemphigus vulgaris.

This article discusses the temporary scalp trichopigmentation procedure, detailing its unique approach compared to traditional scalp micropigmentation, and reports no new clinical findings.

This study found that variations in propylene glycol concentration in wax apple leaf extract hair tonic affected pH, specific gravity, and viscosity, aligning with SNI requirements.

In this case report, a 20-year-old male with tricho-rhino-phalangeal syndrome was found to have a de novo frameshift mutation in the TRPS1 gene, highlighting the challenges in diagnosing this rare disorder.

This study found that SYP123 and VAMP727 are involved in the secretion and transport of inner cell wall components, which is crucial for hardening the root hair shank in Arabidopsis.

This study suggests that chronic treatment with TPA in mouse skin selectively expands a keratinocyte subpopulation hyperinducible for ODC, which may be a key target for neoplastic transformation.

This study found no difference in the physical stability of hair tonic preparations made from sansevieria leaves extract, regardless of whether maceration or soxhletation methods were used.

This study found that in mouse skin, the activation of stem/progenitor cells is synchronized across different niches during growth, with the glutamate transporter SLC1A3 playing a crucial role in this process.

This study found that overexpression of Claudin 6 in mice led to incomplete epidermal formation and hair abnormalities, suggesting its crucial role in skin differentiation and hair follicle development.

This study found that Y27632 treatment facilitated the formation of core-shell-shaped hair follicle organoids, resulting in nearly 100% efficient hair shaft sprouting in vitro.

This study found that Gsdma3 mutation in mice allows hair follicles to bypass a typical telogen phase and directly enter the anagen phase, suggesting Gsdma3's role in hair cycle transitions by regulating Wnt signaling.

In this study, sequences upstream of the TGM3 gene were found to regulate epithelial-specific gene expression in keratinocytes, suggesting potential applications in gene therapy.

A 4kb fragment of the desmocollin 3 promoter targets gene expression to specific skin and hair follicle areas.

This study found that CLK1 is necessary for epidermal differentiation but does not affect sebocyte differentiation in a telogen skin stem cell line.

This article discusses the impact of the tabby mutation on secondary vibrissae and hair follicle patterns in mice and reports no new clinical results.

PP405 may help hair growth by activating hair follicle stem cells.
