In this study, mouse sweat gland development relied on a regulatory sequence initiated by Wnt/β-catenin signaling, and disruptions in Wnt, Eda, or Shh pathways led to distinct developmental failures.

This study found that beard hair medulla cells express an unexpected range of keratins, showing variability and promiscuous behavior in keratin interactions distinct from other hair follicle cells.

This study found that scalp involvement in dermatomyositis consistently shows a nonscarring pattern with chronic telogen effluvium, featuring telangiectasia and mucin deposition as universal histologic markers.

This study identified chemokine receptor ligands cxcl10 and cxcl11 as new hair-specific transcriptional targets of the Eda pathway, suggesting chemokine signaling plays a role in primary hair follicle patterning.

This study found that combining herbal extracts with PRP increased human dermal papilla cell proliferation via ERK and Akt protein regulation, suggesting its potential for developing hair growth therapies.

This review discusses the development and role of corneodesmosin in skin and hair follicle integrity, highlighting findings from mouse models and its connection to genetic diseases, with no new experimental results included.

This study found that combining microneedling with 5% minoxidil improved hair growth in Chinese men with androgenetic alopecia, possibly through activating the Wnt/β-catenin signaling pathway.

In this research letter from the British Journal of Dermatology, the authors explore the use of topical tofacitinib to treat alopecia areata affecting facial hair, but specific results are not reported in the abstract.

This study found that topical clobetasol propionate cream provided a modest improvement in hair regrowth for alopecia areata patients, though those with atopy had higher relapse rates after treatment completion.

This historical review examines the diagnostic and etiological understanding of alopecia areata, emphasizing the evolution of theories and the impact of immunological data, while providing no new clinical results.

Lichen planus pigmentosus and fibrosing frontal alopecia in Colombia are likely different stages of the same disease.

This case study suggests that trichoscopic examination of the beard can aid in diagnosing frontal fibrosing alopecia in men, especially when challenging to differentiate from androgenetic alopecia.

This review provides a detailed overview of the causes, prevalence, pathophysiology, clinical presentation, and treatment of beard alopecia, highlighting conditions such as alopecia areata, pseudofolliculitis barbae, and tinea barbae, and aims to serve as a resource for clinicians handling such cases.

In this cross-sectional study conducted at Farhat Hached Hospital in Tunisia, more than half of the 60 alopecia areata patients surveyed experienced depression, particularly younger individuals and those with severe or specific forms of the condition, underscoring the need for psychological support.

This case report highlights the successful treatment of a 37-year-old male with steroid-resistant beard alopecia areata using baricitinib, a JAK-1/2 inhibitor, over 9 months, resulting in reduced hair loss and improved hair density.

In this study, topical tacrolimus 0.03% cream showed good to excellent response in treating alopecia areata in 70% of participants, with no cutaneous or systemic side effects observed.

This study found that patients with alopecia areata experience significant impairments in health-related quality of life, notably affecting mental health, according to various quality of life assessment tools.

This review article provides an updated overview of the pharmacology, mechanism of action, clinical efficacy, and adverse events associated with topical minoxidil, a widely used treatment for androgenetic alopecia and other hair loss conditions, while noting that its exact mechanism is still not fully understood.

In this study, tofacitinib treatment was associated with significant hair regrowth in two patients with alopecia universalis over eight months, with minimal adverse effects reported.

This retrospective review found that while intralesional corticosteroids provided symptomatic improvement for lichen planopilaris, hydroxychloroquine with topical corticosteroids led to higher remission rates but did not result in visible hair regrowth.

Treat scalp and beard fungal infections early with oral antifungal medication and sometimes topical therapy, avoiding unnecessary allergy tests and surgery.

Hair transplant combining scalp and beard hair with PRP was successful for scarring alopecia.

This article describes refined techniques in facial hair transplantation for increasing demand in restoring eyebrow density in women and achieving fuller beards in men, without presenting new clinical results.

This vodcast discusses various tools for assessing the severity of alopecia areata, emphasizing the importance of considering psychosocial impacts alongside physical symptoms.

The researchers reported that one-third of women with female pattern hair loss in their study had occipital region involvement, which is important for diagnosing and planning treatment, including hair restoration surgery, as the occipital region is often used as a normal reference.

In this study, the HairCheck device was reported to accurately assess changes in hair density and diameter, suggesting its usefulness in monitoring alopecia progression and treatment response.

This review discusses the importance of early diagnosis and the management of hidradenitis suppurativa, reporting no new clinical results but highlighting current therapeutic approaches and need for collaboration in treatment.

This study found that trichoscopic examination is useful for diagnosing and monitoring systemic lupus erythematosus, with severe diffuse non-scarring alopecia indicating active disease.

This study found that Black patients with discoid lupus erythematosus had significantly worse CLASI damage scores and higher odds for dyspigmentation, scalp involvement, and scarring alopecia compared to non-Black patients.

This study found no significant association between vitamin D levels and alopecia areata in patients when gender was accounted for, but vitamin D levels were lower in patients with nail involvement.
