This systematic review suggests that interactions between hair follicle stem cells and lymphatic vessels are crucial for hair growth and tissue regeneration, offering potential targets for treating hair loss and enhancing wound healing.

Proteins like aPKC and PDGF-AA, substances like adenosine and ATP, and adipose-derived stem cells all play important roles in hair growth and health, and could potentially be used to treat hair loss and skin conditions.

This study found that nutritional supplementation improved hair loss in women with telogen effluvium, showing a significant increase in anagen hairs and reduction in telogen hairs after three months.

This study found that LDE225, a novel Smo antagonist, shows potential as a topical treatment for basal cell carcinoma due to its high affinity binding and effective inhibition of tumor growth in preclinical models.

This study suggests that PDGFA and BMP2 play a role in the hair follicle cycle in cashmere goats, with PDGFA particularly involved in activating the growth phase.

The researchers reported that exposure to long days after short-day treatment induced a synchronized, out-of-season wool growth cycle in New Zealand Wiltshire sheep, similar to cycles induced in other species.

This study observed that in men with androgenetic alopecia, frontal hair regions showed reduced density, diameter, and growth rate compared to occipital regions, worsening with advanced stages.

In this study, a synthetic antagonist of the p75 neurotrophin receptor was found to significantly inhibit hair follicle regression in murine skin cultures, suggesting a potential role in treating hair disorders characterized by premature catagen entry.

This review discusses the structure, functions, and growth cycle of human hair, emphasizing its reduced growth and protective roles, and reports no new research findings.

This study concludes that SPARC is likely a secondary response during the hair cycle's transitional phases, indicating tissue-remodeling processes similar to those in wound repair, rather than initiating these transitions.

Caspase-7 has functions in skin and hair that are not related to cell death.

This study suggests that EDA-A2 induces apoptosis in hair follicles by increasing DKK-1 expression, implicating EDA2R signaling as a potential therapeutic target for androgenetic alopecia.

This study suggests that the down-regulation of 14-3-3 proteins in wild-type keratinocytes, absent in Smad4 mutant keratinocytes, might contribute to the failure of hair follicles to initiate catagen in Smad4 knockout mice.

This study found that miRNA biogenesis, facilitated by Dicer and Drosha, is crucial for adult hair follicles' growth and regeneration, highlighting their multiple roles during the hair follicle growth cycle.

This study found that ocu-miR-205 promotes the apoptosis of dermal papilla cells and the transformation of hair follicles from growth to regression and resting phases in Rex rabbits.

This study suggests that Myelin Protein Zero-like 3 plays a crucial role in hair follicle cycling by regulating anagen and catagen phases, mediated through mitochondrial signaling mechanisms in both human and murine hair follicles.

This study found that dopamine directly induces the catagen phase in human scalp hair follicles in vitro.

This study found that KAP and KRTAP genes positively correlate with the cashmere growth cycle, and their regulation aligns with the growth phases of cashmere in secondary hair follicles.

This study found that overexpression of parathyroid hormone-related protein in mice resulted in 30–40% shorter hair due to premature transition into the catagen phase of the hair cycle.

This study found that human hair follicles can be maintained in vitro for at least seven days before they start to show signs of transitioning into the catagen phase.

In this study, the researchers found that KAP3.1, KRTAP 8-1, and KRTAP 24-1 genes positively correlated with the growth cycle of cashmere in Inner Mongolia goats, aligning with the observed hair cycle phases.

This study found that ocu-miR-205 influences hair follicle density in Rex rabbits by promoting dermal papilla cell apoptosis and transforming hair follicles from growth to resting phases through signaling pathway modulation.

This study found that using a commercially available IPL home-use device led to significant hair reduction and demonstrated long-term efficacy in maintaining hair reduction one year after treatment.

This review discusses the genetic and molecular factors involved in human hair follicle development and cycling, highlighting identified genes and pathways associated with hair diseases but reports no new results.

This study found that a 4-week treatment with an ayurvedic anti-dandruff regime was highly effective and safe, significantly reducing dandruff flakes and scalp itch in all Indian participants with moderate dandruff, while lowering histamine and oxidative stress markers without reported side effects.

This study found that all-trans retinoic acid (ATRA) inhibits proliferation and promotes apoptosis in secondary hair follicle-derived dermal papilla cells from cashmere goats, likely via the TGF-β2/Smad2/3 signaling pathway.

In this study, researchers found that miR-143-3p may play a novel role in cashmere growth by directly repressing the expression of Itga6 in secondary hair follicles of goats.

This study discovered that key genes like KAP3-1 and KRTAPs are closely linked to the growth cycle of cashmere in Inner Mongolian goats, identifying March as the primary cycle's onset.

This study suggests that heparan sulfate is crucial for regulating hair follicle formation, cycling, and gland morphogenesis, with its ablation leading to continuous hair growth and increased gland activity in mice.

This research discusses a novel imaging approach in live mice to study stem cell and niche interactions in tissue homeostasis and reports no new results.
