This study found that topical diphenylcyclopropenone was effective in treating severe alopecia areata but had a high relapse rate and was often accompanied by side effects like eczema and lymphadenopathy.

This study found that prostaglandin D2 promotes androgen receptor and AKT signaling in human dermal papilla cells through the DP2 receptor, potentially contributing to androgenetic alopecia.

This study found that TPA treatment transiently induces high levels of ODC in mouse epidermal cells, particularly around hair follicles, with localization reduced by retinoic acid or cycloheximide pretreatment.

This case report identifies a novel LIPH gene mutation linked to autosomal recessive woolly hair/hypotrichosis in a Japanese boy, expanding the spectrum of known mutations associated with this condition.

This study outlines a method for isolating dermal papilla cells from human hair follicles, which may help overcome challenges in studying their role in hair growth.

In this case report, a 9-year-old boy with diffuse alopecia areata showed improvement with topical diphencyprone immunotherapy, suggesting it as a safe and effective treatment option in pediatric cases of alopecia areata resistant to other therapies.

LIPH mutations cause woolly hair in some Chinese people.

This source explains that Equine Cushing’s disease, or PPID, in horses is due to the degeneration of brain cells producing dopamine, leading to elevated cortisol levels and characteristic symptoms; it outlines diagnosis methods and emphasizes life-long pergolide treatment to manage the condition.

This study found that human placenta hydrolysate effectively inhibited atopic dermatitis development in stimulated human cells and a mouse model, suggesting its potential as a therapeutic agent for related skin diseases.

This study found that a single intradermal injection of human dermal papilla cells increased hair follicle number and thickness in pigs, suggesting potential effectiveness for hair growth in humans.

A gene called APCDD1, which controls hair growth, is found to be faulty in a type of hair loss called hereditary hypotrichosis simplex.

This study found that diphenylcyclopropenone therapy resulted in over 50% hair regrowth in 71% of alopecia totalis patients, with a significant relapse association with thyroid disease, suggesting treatment could be viable but should continue for at least two years.

This study reviewed evidence suggesting that the loss of dermal white adipose tissue (dWAT) during menopause may be linked to decreased estrogen levels, potentially affecting skin health, and discussed non-hormonal treatments, like magnolol, that might help restore dWAT and improve menopausal skin changes.

This review discusses recent advances in understanding the molecular landscape of the dermal papilla, particularly focusing on Blimp1's role in hair follicle development and potential therapeutic targets for hair regeneration, but presents no new clinical results.

In this study, rice straw-derived smoke water enhanced root growth in rice plants by increasing root meristem size and cell proliferation, reducing superoxide accumulation under phosphorus deficiency, and altering internal phosphorus partitioning, although it suppressed root hair elongation, which affected phosphate uptake.

This case report suggests that topical diphenylcyclopropenone (DPCP) may be beneficial for treating both alopecia areata and verruca vulgaris, although it is not typically a first-line therapy.

This letter discusses three plasmacytoid dendritic cell-related parameters that may help differentiate lupus alopecia from lichen planopilaris, but it reports no new study results.

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.

This study explores the expression and function of 11β-HSD1 in human hair follicles and its potential regulation of glucocorticoid effects on dermal papilla cells, but reports no definitive findings on 11β-HSD1's role.

In this study, clinically used preoperative skin preparations with povidone iodine and chlorhexidine gluconate did not meet FDA log-reduction standards for bacterial bioburden in a porcine model, suggesting persistent infection risks.

This research reported that dermal progenitor cells can enhance split-thickness skin graft outcomes by improving dermal layer qualities and reducing itch and offer potential in skin wound healing using a flowable hydrogel for better cell delivery and survival.

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

This study reported that weekly intramuscular dexpanthenol may improve quality of life and satisfaction with hair appearance in women with female pattern hair loss, with no side effects observed.

Among pediatric alopecia areata patients treated with DPCP, this study reported complete hair regrowth in 8.8% and any regrowth in 61.8% after one year, with better outcomes for those with milder initial symptoms and longer treatment durations.

Blocking a protein called prostaglandin D2 might help treat hair loss.

This study suggests that while DI water significantly impacts hair, the effects of citric acid, hydrogen peroxide, and sodium chloride in shampoo on hair remain unclear, requiring further investigation.

This study investigated a nanostructured system using PS-b-PAA diblock copolymer for incorporating the hydrophobic photosensitizer ClAlPc, finding it effective in causing cellular damage in Caco-2 cells under light while demonstrating no cytotoxicity without light, suggesting its potential use in photodynamic therapy.

Minoxidil solution applied twice daily improved hair growth in patients with Woolly Hair/Hypotrichosis due to LIPH gene issues, with mild side effects.

This study concluded that both DPCP alone and combined with PRP are effective and safe for treating severe alopecia areata, with no significant difference between the two treatment methods.
