This paper presents a culturally informed protocol designed to improve the collection of hair samples from African Americans for cortisol measurement, illustrating its application with community-based study data.

In this self-controlled comparative study of 16 women with Female Pattern Hair Loss, MMP® with Minoxidil showed a better response in the parietal-vertex regions in less advanced cases compared to standard Minoxidil treatment, though overall effectiveness was similar.

This study found that testosterone impacts hair follicles from different scalp regions differently in male pattern androgenetic alopecia, challenging the belief that occipital scalp follicles are androgen-insensitive.

This study found that testosterone impacts hair follicles from both affected and occipital regions in male pattern androgenetic alopecia, but with different androgen response-profiles, challenging the belief that occipital regions are androgen-insensitive.

This study reported that polyamine levels, especially N-acetyl polyamines, were higher in the vertex region of the scalp than in the occipital region in patients with male and female pattern hair loss.

This study reported that using 5% minoxidil topical foam twice daily improved hair density and width in both the frontotemporal and vertex regions of men with moderate androgenetic alopecia.

This study reported that two male patients with diffuse unpatterned alopecia exhibited donor-area involvement in both the vertex and occiput, challenging the assumption of occipital stability for hair transplantation, and showed partial improvement following treatment with oral finasteride and topical minoxidil.

This review discusses the increasing importance of hair analysis in forensic toxicology and highlights the complexities in interpreting results due to external contamination and regional collection differences, but reports no new findings.

This study found that topical minoxidil 5% foam was effective in promoting hair growth in both the frontal and vertex scalp for men with androgenetic alopecia.

The authors suggest that during hair transplantation for hair loss, the parietal eminence area should be prioritized along with the mid-scalp to address future noticeable thinning, especially since this area often becomes more conspicuous over time.

This study suggests that acquired progressive kinking of hair, which typically appears at or after puberty, may be androgen dependent and could progress to male pattern baldness.

The researchers reported that various environmental factors and higher testosterone levels were linked to different patterns of hair loss in women with androgenic alopecia.

This review covers female pattern hair loss, outlining its progression, existing treatments like topical minoxidil and laser therapy, and notes that anti-androgen therapies need further investigation.

This article previews a Journal of Investigative Dermatology quiz on diagnosing male androgenetic alopecia and offers no new research results.

This study found that patients with androgenetic alopecia had increased scalp microbial diversity and reduced Staphylococcus abundance, particularly in the frontal and vertex regions, suggesting this dysbiosis as a sensitive indicator of AGA.

In this study, a combination treatment of microinfusion (MMP®) and topical minoxidil showed a modest increase in hair density in a 28-year-old woman with chronic telogen effluvium, particularly in the parieto-vertex region, suggesting potential benefits but underscoring the need for larger trials to confirm efficacy.

This study found that the gene for the enzyme aromatase is expressed in scalp hair follicles of women and is negatively correlated with LH levels, potentially reflecting the hormonal environment of hair follicles in PCOS.

This case report described a woman who developed hair matting and traction alopecia after using a homemade shampoo with Hibiscus rosasiensis leaves, which was mitigated by cutting the matted hair.

This study reported complete clinical clearance of tinea capitis in a 3-year-old boy after 8 weeks of treatment with oral griseofulvin and ketoconazole shampoo.

This review discusses loose anagen hair syndrome, a benign and self-limited condition predominantly affecting children, and highlights the importance of differentiating it from other hair disorders like telogen effluvium and trichotillomania, but reports no new results.

In this case report, a 36-year-old male with androgenetic alopecia showed clinically visible improvement in hair density after three monthly sessions of microneedling combined with exosome application, although the authors note that further studies are needed to verify these findings.

This study observed that 5% minoxidil topical foam alters gene expression and signaling pathways in the scalp, providing insights into its mechanism of action in men with androgenetic alopecia.

This case report describes a 52-year-old black woman with diffuse scalp swelling and thinning hair attributed to a large increase in the thickness of scalp subcutaneous fatty tissue.

Miniaturized hair follicles in androgenetic alopecia show abnormal mitochondrial activity and damage.

This study compared the diagnostic effectiveness of Folliscope and Trichoscope in 100 men with androgenetic alopecia, concluding that using both methods enhances diagnostic accuracy by providing complementary insights—Trichoscope highlights patterns while Folliscope offers objective measurements.

Atypical male hair loss may not respond to usual treatments.

This case report describes a 21-year-old man with alopecia areata presenting as a U-shaped hair loss pattern resembling Hamilton grade VII male-pattern baldness, with no signs of inflammation or related conditions.

In this study, lupus panniculitis of the scalp was associated with a high incidence of recurrence and progression to systemic lupus erythematosus, despite various treatments showing complete response within weeks.

This report describes a rare case of alopecia areata-like psoriasis, associated with skin lesions, following the use of dupilumab in a patient with atopic dermatitis.

This study found that patients with androgenetic alopecia experienced more severe symptoms than those with alopecia areata, influencing their quality of life differently based on various patient characteristics.
