This study emphasized that trichoscopy and ultraviolet-enhanced follicular dermoscopy enhance diagnostic accuracy in adolescent alopecia, while systemic JAK inhibitors offer promising treatment options, reflecting the need for specialized, etiology-driven approaches and highlighting knowledge gaps in prevention and long-term outcomes.

In this study, researchers developed a novel nucleic acid nanoparticle system incorporating quercetin, which they found enhances functional hair follicle regeneration and maintains epithelial structure stability in androgenetic alopecia by regulating hair follicle stem and dermal papilla cells.

This study reviews 3D printing's role in neurology, highlighting its potential to enhance hair restoration and scalp therapy through personalized solutions, while acknowledging the challenges of regulatory issues and the need for further research on long-term effects.

This study found that telogen, a resting phase of the hair follicle cycle, is characterized by dynamic gene expression, including enhanced cholesterol metabolism and immune signaling, suggesting it is an active regulatory phase despite its quiescent appearance.

This study demonstrated that culturing high-passage dermal papilla cells with specific supplemented conditioned media may preserve their hair-inducing abilities, suggesting potential for reconstructing new hair follicles in vivo.

This review discusses investigational treatments for androgenetic and chemotherapy-induced alopecia and reports no new clinical results, highlighting the need for further research.

This study found that Phaeodactylum tricornutum extract enhanced hair follicle cell proliferation, indicated by increased keratin and ERK1/2 signaling, suggesting its potential for hair care applications.

This study found that plantar dermis matrix homogenate can partially restore the regenerative capacity of hair follicles impaired in culture, with CTHRC1 playing a critical role in this process.

This study highlighted the potential of iron chelators, deferoxamine and deferiprone, to improve hair density, thickness, and elasticity and reduce hair loss by up to 66.8% over six months in individuals with autoimmune alopecia, suggesting they may offer a promising therapeutic option.

Immune cells called Treg cells are essential for hair growth and regeneration.

This study found that a single dose of TRP significantly reduced the number of UV-B-induced actinic keratosis lesions in a mouse model and was associated with improved skin histology and minimal side effects.

AGA is a genetic, hormonal hair loss treated with finasteride, minoxidil, and supplements, but new compounds are being developed.

In this case report, a 25-year-old transgender woman on testosterone-blocking therapy developed generalised hypertrichosis after starting ciclosporin for severe plaque psoriasis, illustrating that ciclosporin can induce this side effect even under androgen suppression.

A girl with red hair developed hair-pulling and body image disorders after being bullied for her hair color.

In this study, trichoscopic features aiding differential diagnosis of alopecia in Korean patients were found to be similar to those in Caucasians, but pigment pattern frequencies differed due to racial characteristics.

Long-standing benign tumors can become cancerous, especially in people with weakened immune systems.

In this study, researchers differentiated induced pluripotent stem cells into cells with dermal papilla-like properties, demonstrating their potential role in hair follicle bioengineering and drug testing for hair growth.

This study suggests that 3D spheroid cultivation of dermal papilla cells can restore their hair-inductive capabilities, which are lost in 2D-cultured cells.

This review discusses the history and challenges of hair follicle regeneration using follicular fragments and dissociated cells, without presenting new clinical results.

This study demonstrated that optical coherence tomography effectively detects significant changes in hair structure caused by steroid treatment, suggesting its potential use in doping control and clinical therapy monitoring.

This abstract introduces TrichoFoam™, a new foaming vehicle for compounding pharmacies, designed to be a gentle, non-irritating option for alopecia treatment, acknowledging that current topical treatments are limited and oral products may cause adverse effects.

This study found that trichoscopic parameters in male androgenetic alopecia deteriorated progressively with increasing disease severity and were significantly linked to genetic, metabolic, and psychosocial factors.

This study found that sulforaphane and its related compounds may promote hair follicle growth in mice, suggesting their potential as treatment agents for androgenic alopecia.

This study suggests that Terminalia chebula fruit extract may promote hair growth in androgenetic alopecia by activating specific signaling pathways and inhibiting 5α-reductase, showing effectiveness comparable to finasteride.

This review discusses nearly 70 patent applications for the treatment of androgenetic alopecia and other hair conditions, highlighting the mechanisms of action explored but reports no clinical results.

This article reviews the development of a topical hair growth agent using natural extracts and reports no new clinical results, emphasizing the need for further evaluation of its efficacy.

This study suggests that targeting the endocannabinoid system through pharmacological interventions may help reduce compulsive hair-pulling in individuals with trichotillomania.

New hair regrowth model introduced, imiquimod kills skin cancer cells, T-cadherin loss makes skin cancer more invasive, no strong link between PTCH1 gene and skin cancer after transplant, and male teens more likely to have hereditary hair loss.

This study presents a case of a 6-month-old infant girl with hypotrichosis and an alopecic plaque in the occipital region, characterized by broken and dystrophic hairs with follicular papules and perifollicular hyperkeratosis, suggesting a diagnostic consideration.

This study found that topical trypsin application after hair removal in mice led to cell death at the follicular papilla, which delayed hair growth and pigmentation.
