The authors of this study concluded that higher calcium levels in hair may indicate early metabolic changes leading to osteopenia or osteoporosis in menopausal women, even before detectable by standard DEXA imaging.

This study in young Ukrainian men found that specific body measurements, like shoulder width and tibia epiphysis width, are highly predictive of alopecia areata occurrence, though not for its progression, using discriminant models (p<0.001).

This study of baricitinib in adults with severe alopecia areata found that after initial success, 10.9% of participants lost treatment response by Week 152. Factors like longer disease duration and severe baseline symptoms were more common in those losing response.

This abstract discusses clinical techniques for diagnosing female pattern hair loss and reports no new research findings.

This study found that Bone morphogenetic proteins (BMPs) play a crucial role in dermal papilla cells' ability to induce hair follicle stem cell differentiation, and that androgens may impair this process by downregulating BMPs.

This study found that androgenetic alopecia can affect the occipital region in men with advanced stages of the condition.

This study examined the application of new clinical guidelines for diagnosing frontal fibrosing alopecia in 18 men, highlighting that current diagnostic criteria may often overlook early beard involvement and sideburn recession.

Frontal fibrosing alopecia can affect men's beards and leads to permanent hair loss.

In this case report, a 35-year-old man developed avascular necrosis after receiving intradermal corticosteroid injections for alopecia areata, marking the first documented instance of this side effect from such treatment.

This article reviews various aspects of hair and hair loss but does not report new research findings.

In this study, researchers found that 68% of orthodontic patients with oligodontia displayed hair disorders, such as hypotrichosis and androgenetic alopecia, highlighting trichoscopy and trichogram as valuable diagnostic tools to distinguish between isolated and syndromic forms of the condition.

This correspondence discusses eyebrow alopecia in the context of centrofacial trichoblastomatosis and reports no new clinical findings.

This article provides no new data as it is a letter to the editor and lacks an abstract, focusing instead on discussing aspects of hair loss in the elderly without presenting research results.

This review discusses the increased autoimmune events associated with the use of denosumab, a biologic agent for managing postmenopausal osteoporosis and skeletal complications from malignancy, but reports no new data.

In this study, hair density and thickness in nonbalding scalp areas varied with the severity and BASP subtypes of androgenetic alopecia in East Asian men, showing notable decreases in some subtypes.

This study found that hair shaft miniaturization in aging and genetic hypotrichosis leads to hair follicle stem cell loss through mechanical compression and apoptosis mediated by the Piezo1 channel.

In this study, researchers examined men with early-stage androgenetic alopecia and found distinct patterns of hair loss correlated with genetic and hormonal factors, noting that parietal region pattern hair loss responded better to minoxidil and micronutrient treatment compared to occipital region pattern.

This discussion suggests that acquired progressive kinking of hair in androgen-dependent scalp areas may indicate the early stages of androgenetic alopecia with a poor prognosis, but it offers no new clinical findings.

The study observed that in women, the number of hair follicles with an internal root sheath decreases with age in the parietal region, also hinting at a reduction in hair follicle and shaft width.

This study found that older men with vertex balding have lower circulating levels of the protein IGFBP-3 and higher levels of IGF-1.

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.

Patients with Focal Dermal Hypoplasia often experience skin, nail, hair, and bone issues, and may benefit from calcium and vitamin D supplements.

This study found that young adult Ukrainian men with alopecia areata had significantly different skinfold thickness at several body sites compared to healthy peers, suggesting unique patterns of fat distribution associated with the disease.

This study found a significantly higher frequency of females with six or more fingerprint arches among those with alopecia areata compared to controls.

In this study, centralised measurements provided more consistent and accurate results for assessing hair loss in mild-to-moderate alopecia areata, reducing error compared to local ratings.

This study found that the parietal/occipital hair density ratio decreases significantly only when baldness is visibly present, making it no better than the Hamilton/Norwood scale for assessing baldness severity.

Women with thinning hair have thinner hair strands than women without hair loss.

This study found that in androgenic alopecia, the arrector pili muscle degenerates and is replaced by fat, unlike in normal skin or telogen effluvium.
