This study found that the occipital scalp is significantly involved in female pattern hair loss, with some patients showing clinically visible alopecia.

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

This study observed that cathepsin L and transglutaminase 3 colocalize in the human hair bulb and nail matrix, suggesting their involvement in terminal differentiation within these epidermal appendages.

This study examined the clinicopathologic and trichoscopic characteristics of keratosis follicularis spinulosa decalvans and identified terminal hair involvement and follicular hyperkeratosis as key diagnostic features.

This open-pilot study found that topical 1% sildenafil did not show significant hair growth in children with alopecia areata, as outcomes seemed due to spontaneous disease regression.

This study examined 15 female patients with hypothyroidism to investigate the characterization of their alopecia and ruled out other causes, using medical histories, and clinical, trichoscopic, and histologic findings.

This study reviewed clinical trials and found that low-level laser therapy significantly increased hair diameter or density in both men and women with pattern hair loss compared to a sham device, though the involvement of industry relationships in some studies suggests cautious interpretation.

This study found that alopecia areata often affects beard hair as frequently as scalp hair, leading the authors to propose a new scoring system and a subtype called alopecia subuniversalis for extensive hair involvement.

This study found that β1 integrin expression may serve as an indicator of androgenetic alopecia severity and could be involved in the disease's development.

This study demonstrates that PAD1 and PAD3 are involved in hair follicle differentiation, while PAD1 and PAD2 may play a role in the physiology of sweat glands and arrector pili muscles.

This study found that Cathepsin E plays a crucial role in keratinocyte terminal differentiation, affecting epidermis formation and homeostasis in mice.

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.

Matriptase is crucial for skin barrier, hair growth, and may contribute to skin cancer.

This study identified key dermoscopic features in folliculotropic mycosis fungoides patients, showing that dilation of follicular openings and spiky follicular keratosis are specific indicators of follicular involvement, potentially aiding in diagnosis, classification, and treatment decisions.

This study reports that caspase-14's expression pattern in the epidermis and hair follicles is highly conserved across diverse mammalian species, suggesting its early evolutionary role in mammalian skin maturation.

This study found that diphenylcyclopropenone therapy resulted in over 50% hair regrowth in 71% of alopecia totalis patients, with a significant relapse association with thyroid disease, suggesting treatment could be viable but should continue for at least two years.

This study found that GLI2 plays a key role in activating follistatin, an activin/BMP antagonist, in response to hedgehog signaling in human epidermal cells, with implications for hair follicle development and basal cell carcinoma.

ZPK helps skin cells mature and may affect skin health.

Hidradenitis Suppurativa is a chronic skin condition best treated early with surgery for better outcomes and less recurrence.

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

This case report describes a unique instance of an otherwise healthy infant with phylloid terminal hair nevus, a form of hypomelanosis without extracutaneous abnormalities.

This review discusses the molecular mechanisms of androgen action in human hair follicles and reports no new findings; the authors emphasize the need for further research to improve treatments for hair disorders.

This study found that 23.8% of participants with pattern hair loss had occipital involvement, with higher rates in females (35.6%) compared to males with early-stage hair loss (12.1%), illustrating significant gender differences in hair loss progression.

This study found that p53 plays a crucial role in regulating apoptosis during hair follicle regression (catagen) in mice, and its absence leads to delayed progression and altered expression of apoptosis-related markers.

This article reports a rare combination of rapid-onset halo nevi, nonsegmental vitiligo, and premature scalp hair graying.

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.

This case study reports on an 11-year-old boy with woolly hair nevus, featuring twisted hair shafts and an abnormal hair cuticle, alongside epidermal nevi on his face and back.

This article reviews current knowledge on the causes, diagnosis, and medical treatments for androgenetic alopecia, particularly in men, and reports no new findings.

This article reviews common causes of hair loss, noting that a well-directed history and examination are often sufficient for diagnosis, and reports no new clinical findings.

This study found that higher levels of the protein Flii were associated with enhanced hair follicle regeneration and longer hair fibers in a mouse model.
