In this study, the novel topical agent PP405 showed favorable tolerability and increased hair density by over 20% in men with advanced androgenetic alopecia after eight weeks, suggesting a promising potential treatment pending further trials.

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

This thesis investigates the underlying mechanisms and treatment options for androgenetic alopecia, highlighting the molecular roles of androgens and genetic predispositions, and evaluates current and emerging therapies, such as PROTACs and Janus Kinase inhibitors, to enhance patient management.

This review highlights the limitations of existing hair loss treatments like minoxidil and finasteride and suggests that future therapies may benefit from focusing on antibody and cell-based treatments, which offer targeted and potentially transformative options for managing hair loss disorders.

The Dfl mutation in mice causes poor sebaceous gland function and complete hair loss.

Artificially inducing hair regrowth in mice can change the normal pattern and timing of hair growth, with minimal color differences between old and new fur.

Proteomic analysis can identify genetic differences in mouse hair, helping understand hair defects and variations.

This study describes the pelage cycle, hair types, and molt patterns in black-tailed deer, highlighting significant differences in hair properties among various developmental stages and populations.

This study observed that pelage development in male blue foxes born in early June was more synchronized than those born in early May, with differences likely influenced by melatonin levels.

Minoxidil does not specifically target any hair follicle cells.

This study found that a large number of pelage hair follicle mesenchymal stem cells can be efficiently isolated using two-step Ficoll Density Gradient Sedimentation, promoting hair growth by secreting exosomes in mice.

This study reported that pelage hair follicle mesenchymal stem cells isolated from mice using Ficoll Density Gradient Sedimentation can be obtained in large numbers and may promote hair growth via exosome secretion.

This study found that follistatin and activin interactions are important for hair follicle development and cycling in mice, suggesting that they may regulate processes involving BMP-2 and its antagonist.

This study found that the pituitary gland is crucial for normal pelage color cycles in weasels, with certain hormones influencing regrowth of pigmented or white hair after molting.

This study found that in mink, the pituitary gland is essential for normal seasonal pelage cycles, and manipulating hormone levels can affect hair growth and type.

This study reports that prenatal and prepubertal exposure to organochlorine compounds and perfluoroalkyl substances may affect pubertal development at age 12, with observed changes in development patterns in both girls and boys, highlighting the need for further research.

This study found that defective cross-linking in hair cuticles is observable in a minority of mouse hair mutants, suggesting different proteins are involved in cross-linking across cell types.

This study observed defects in hair cuticle cross-linking in some, but not all, mouse mutants with sparse or structurally unsound hair.

This study suggests that the COX-2 enzyme plays a role in hair follicle biology, as transgenic overexpression in mice induced hair follicle cycling disturbances and alopecia, which was mitigated by COX-2 inhibition.

This study found that osteopontin mRNA is abundantly expressed in dermal papilla cells during the catagen phase of hair growth in rats, suggesting a role in this phase.

This study reported that in the California Ground Squirrel, certain elements bioaccumulate in hair, providing baseline data for environmental health assessments.

In this study, prenatal exposure to all-trans-retinoic acid in pregnant mice resulted in increased BrdU-positive nuclei in hair bulbs without altering hair follicle morphogenesis, suggesting potential for non-teratogenic studies on skin diseases.

This study identified genetic differences between Australian White Sheep and Hu Sheep that may explain their distinct pelage types, with a focus on subcutaneous adiposity and immunoregulation. The findings suggest potential targets for breeding climate-resilient sheep, enhancing our understanding of heat tolerance in these breeds.

This research observed that, in domestic cats like Maine Coon and Rex breeds, a "piebald" coat color pattern is likely influenced by the Silver locus, although the specific mutations involved are yet to be published.

This study describes a novel method using force-triggered density gradient sedimentation for efficiently isolating dermal papilla cells from neonatal mouse skin, showing promise for hair follicle regeneration research.

In this study, topical application of Neem oil on cats with dermatophytosis significantly improved the appearance of skin and fur, with the best results occurring after 15 to 20 consecutive days of treatment.

In this study, researchers found that among adults with severe alopecia, continued treatment with baricitinib for 104 weeks maintained hair regrowth effectively in those who responded at 52 weeks, with improved outcomes noted in some initially non-responders receiving 4 mg.

Minoxidil works in liver and outer hair root sheath for hair growth.
