This study found that applying dexamethasone to mice induced catagen-like follicle changes significantly earlier and more consistently than a vehicle, such changes being useful for studying hair follicle regression.

Diffuse alopecia in women may be related to androgens and iron deficiency, and basic hormone and nutrient screening is useful.

This study found that as hair loss severity increased in women with female pattern hair loss, the number of vellus follicles also rose, indicating miniaturization of terminal hair follicles.

The human hair follicle can store topical compounds and be targeted for drug delivery with minimal side effects.

This study reports that a hair shedding threshold of 100 hairs or more may provide the best concordance with clinical diagnosis for distinguishing chronic telogen effluvium from androgenetic alopecia.

This abstract does not provide specific findings or results.

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

This study found that the yellow dot pattern observed in dermoscopy of alopecia areata corresponds to inefficient follicular structures containing hair remnants, as corroborated by reflectance confocal microscopy and pathological findings.

The conclusion is that small hair follicles cause baldness in macaques, and treatments like antiandrogens and minoxidil can prevent hair loss and promote regrowth.

This study found that red ginseng oil and its major components improved hair regrowth in testosterone-treated mice by promoting an earlier anagen phase and altering related gene expressions.

This study found that platelet-rich plasma injections improved hair density and diameter in women with androgenetic alopecia not responding to other treatments over 24 weeks, with no adverse events reported.

This study reports that versican expression plays a crucial role in maintaining the anagen phase and hair inductive properties, as shown in a transgenic mouse model and hair growth assays.

This article is a letter discussing a clinicopathologic study of 90 cases of trichofolliculoma and reports no new results.

This study concludes that phospholipid–polymer hybrid nanoparticles may be an effective delivery system for quercetin in treating androgenic alopecia by improving hair regrowth and preventing hair follicle cell apoptosis in rat models.

In this study, severe diffuse hair loss in patients with systemic lupus erythematosus was associated with distinct clinical, dermoscopic, and histopathological features, which improved alongside treatment of the underlying condition.

This review discusses the use of laser and intense light sources for hair removal and reports no new clinical results; the authors highlight the potential for aesthetic medicine to include these technologies.

This abstract provides website information and publication navigation for JAMA Dermatology, but it includes no research results or study findings.

This study found that topical minoxidil 5% gel and spironolactone 1% gel were both effective treatments for androgenetic alopecia, with a combination of both providing the best clinical response and achieving 100% effectiveness among participants.

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.

The document concludes that early diagnosis is key for treating common baldness in women, but reassurance is often the best approach as hair thinning can be a normal part of aging.

The study found that balding scalps have more thin hairs and larger oil glands, which might contribute to skin conditions related to hair loss.

This study found that IPL hair reduction led to significant decreases in hair count and thickness by promoting hair follicle miniaturization, increased telogen phase, and reduced cell proliferation.

This study identified acute localized telogen effluvium as a histopathologic mechanism for temporal hair loss following rhytidectomy.

This study reported that combined oral finasteride and topical 5% minoxidil treatment in men with male-pattern hair loss improved hair growth by initiating anagen in pre-existing but deficient follicles, yet the growth rates remained unchanged and did not normalize hair productivity.

In this study, algal oligosaccharides effectively countered key factors in androgenetic alopecia pathogenesis, improving hair growth indicators in vitro and in mice.

This study found that tristimulus colorimetry is a sensitive and quantitative method for projecting hair growth rates in depilated mice, and it observed that 890 nm LED irradiation promotes hair regrowth.

This review discusses different forms and patterns of alopecia associated with lupus erythematosus and reports no new clinical results; the authors highlight distinct features of these conditions.

This letter to the editors discusses the nature of alopecia in Cronkhite–Canada syndrome and questions whether it is truly telogen effluvium, but it reports no new clinical findings.

This study found that treating androgenetic alopecia with platelet rich plasma increased hair density and diameter while decreasing the proportion of telogen and vellus hairs.

This study found that Oriental melon leaf extracts promoted hair growth in a mouse model and cultured human hair follicles, suggesting potential use as a treatment for hair loss.
