This study found that latanoprost induces significant growth and pigmentation of lashes and ancillary hairs, with effects mirroring both brief and chronic treatments observed in patients and animal models.

This study found that VEGF significantly enhances perifollicular vascularization during the hair growth phase, accelerating hair regrowth and increasing follicle and hair size, while its inhibition retards hair growth.

This study found that Polygonum multiflorum extract may promote hair growth by inducing the anagen phase in the resting hair follicles of mice.

This study observed that Aconiti Ciliare Tuber extract may promote hair growth in mice by activating the Wnt/β-catenin signaling pathway.

This review outlines a systematic method for diagnosing hair loss and presents no new findings; the authors emphasize the importance of biopsy in cicatricial alopecia cases.

In this animal study, the researchers found that Schisandra nigra extract may promote hair growth by extending the anagen phase and reducing TGF-beta2 expression.

This study found that Rumex japonicus Houtt. root extract promoted hair growth by enhancing cell proliferation and preventing apoptosis in human dermal papilla cells and HaCaT cells, as well as in a mouse model.

This article reviews the mechanism, usage, and alternatives of the medication minoxidil in dermatology and reports no new clinical outcomes.

This review found that while platelet-rich plasma treatment significantly increased hair density compared to baseline in people with androgenetic alopecia, its effectiveness was not significant compared to placebo in most studies.

Lgr5 is a marker for active, long-lasting stem cells in mouse hair follicles.

This study found that keratin 17 and TNFα play interdependent roles in regulating hair follicle cycling, with TNFα required for the anagen–catagen transition and its ablation partially rescuing hair cycling defects in K17-null mice.

This review discusses the various triggers and diagnostic challenges in determining the cause of telogen effluvium-related hair loss, without providing new clinical results.

This study found that valproic acid promoted human hair growth by increasing β-catenin levels, suggesting it may be a potential therapeutic option for alopecia.

This review discusses the potential mechanisms and evidence supporting low-level laser therapy for stimulating hair growth in men and women, while noting its safety and effectiveness but needing further study on specific parameters.

In this study, researchers found that bulge cells in mouse hair follicles undergo transient proliferation during early anagen, indicating their role as follicular stem cells. However, another factor beyond dermal papilla proximity may be required to initiate a new anagen phase.

This review discusses the hair follicle cycle's complex regulation and highlights the potential for targeting catagen control in future therapies without presenting new experimental data.

This study found that p53 plays a crucial role in regulating apoptosis during hair follicle regression (catagen) in mice, and its absence leads to delayed progression and altered expression of apoptosis-related markers.

This study found that prolactin plays a direct role in regulating the timing of hair growth cycles in mice by affecting the skin, rather than through other endocrine factors.

This study found that autophagy plays a novel role in human hair growth, with altered autophagic flux during hair development phases influencing hair follicle behavior in a preclinical model.

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.

In this study, changes in hair cycle phases during pregnancy and the post-partum period showed a rise in telogen rates after delivery, especially among non-breastfeeding women, but no drastic exaggerations were noted.

This study found that lymphatic vessels promote hair follicle growth in mice and may represent new therapeutic targets for hair loss conditions.

This study found that ethanol-extracted propolis stimulated hair growth in mice by promoting the proliferation of hair keratinocytes.

This study found that the synthetic thyroid hormone receptor modulator KB2115 significantly prolonged the growth phase of human hair follicles in culture without altering mitochondrial activity, suggesting potential as a safer hair loss treatment compared to traditional thyroid hormones.

In this study, minoxidil and human platelet lysate affected gene expression related to hair growth signaling pathways in mouse hair follicle cells.

This study suggests that the patchy thickening and reddish discoloration in rabbit skin during the hair cycle may be due to large anagen-phase hair follicles compressing the dermis and increased blood vessels causing redness.

A woman kept her eyelashes during chemotherapy possibly because of her glaucoma eye drops.

This review summarizes expert opinions on the use of approved pharmacologic treatments alongside hair transplantation, highlighting their potential to enhance hair density and regrowth speed while reducing further hair loss, but reports no new clinical trial results.

This clinical study found that Rosmarinum officinalis mother tincture significantly improved hair volume and density in individuals with diffuse hair loss by enhancing hair parameters measured through a hair shedding visual scale and ponytail thickness test.

This review discusses telogen effluvium, a common form of hair loss, and reports no new clinical results; the authors outline possible causes, typical prognosis, and management strategies.
