This study revealed that in androgenic alopecia, the proximal attachment of the arrector pili muscle to the hair follicle is often lost or significantly reduced.

In human follicular cells, this study found that an Annurca apple-based dietary supplement may stimulate the production of hair keratins, suggesting potential benefits for hair growth.

This study found that plasma rich in growth factors (PRGF) as an adjuvant to follicular unit extraction (FUE) surgery may enhance hair graft performance and reduce post-surgical inflammation and pain in hair loss patients.

The researchers reported that follicular unit hair transplantation achieved a mean graft survival rate of 80.67% and significantly improved patient and observer satisfaction in individuals with stable cicatricial alopecia from postsurgical scalp scarring.

This report documented a successful and sustained hair restoration surgery using follicular unit transplantation for temporal triangular alopecia, lasting over six years.

This study identified FP-1 as a highly specific extracellular matrix protein in follicular papilla cells, which may play a role in hair growth regulation during specific hair cycle phases.

This study found that applying topical tretinoin can influence follicular sulfotransferase expression, enabling 43% of predicted nonresponders to minoxidil to respond positively in the context of androgenetic alopecia.

In this study, the researchers found that transplanted hair follicles undergo significant morphological changes, including a thickened dermal sheath and increased hair shaft diameter, which are associated with altered follicular vascularization.

This study found that scalp hair follicles had higher expression of cytokeratin 15 and distinct hair layers compared to other body regions, highlighting differences in hair follicle characteristics.

In this study, treatment with human follicular keratinocyte-conditioned media improved the trichogenicity of cultured dermal cells by activating key signalling pathways, suggesting its potential use in cell therapy for hair loss.

This study found that CD90+ stem cells with fibroblast-like morphology are present in the lower part of the anagen hair follicle in dogs.

This article explores the complexity and significance of the hair follicle, emphasizing new insights into its biological roles and the involvement of p53 in follicular regression.

This study found that patients with severe acne vulgaris had different systemic inflammatory indices and hematologic parameters compared to healthy individuals.

This study found that SesZen-Bio TM, a proprietary extract from Sesbania grandiflora leaves, increased proliferation of hair cells and hair shaft length in vitro and ex vivo, potentially due to activation of the Wnt/β-catenin signaling and stem cell differentiation pathways.

Hidradenitis Suppurativa is likely an autoinflammatory disease, and better understanding its causes could improve treatments.

This in vitro study suggests that factors in the serum of PCOS patients may contribute to ovarian dysfunction, evidenced by higher hormone production and primordial follicle survival compared to control sera.

This study found that using a standardized protocol with microspheres of approximately 1.5 micrometers enhances penetration into hair follicles, particularly when skin is treated with cyanoacrylate skin surface stripping.

This article presents two cases of keratosis follicularis spinulosa decalvans and reviews its features, highlighting characteristic progression from keratosis pilaris in infancy to cicatricial alopecia in childhood.

This study found that women with androgenetic alopecia experience diffuse hair loss due to a decrease in terminal hairs and an increase in vellus hairs per follicular unit.

Tiny particles carrying roxithromycin can effectively target and deliver the drug to hair follicles without irritation.

This study developed a niosomal delivery system loaded with tretinoin and bicalutamide, optimized for follicular targeting in acne management, showing promising accumulation in hair follicles in animal models.

In this case report, eyelash transplantation with leg hair resulted in less frequent maintenance and no need for perming compared to using nape hair donor sources.

In this study, researchers found that punch grafting was more effective than follicular hair transplantation for treating stable vitiligo; however, follicular hair transplantation was found to be cosmetically preferable for exposed areas like the face due to fewer side effects.

This study found that both pretrimmed and direct nonshaven follicular unit extraction techniques are effective for hair transplantation, with pretrimmed having a higher calculated density and longer time requirement than direct.

In this study, transplanted hair follicles from different body sites showed changes in morphology and immune status, suggesting their ability to adapt and function in new recipient areas such as the scalp or eyebrows.

This paper introduces a novel topical booster aimed at enhancing follicular sulfotransferase activity to potentially improve minoxidil response in patients with androgenetic alopecia but reports no new clinical results.

This study found that hair transplantation using the follicular unit extraction method significantly improved hair density and patient satisfaction in males with androgenetic alopecia, especially those younger than 33 and with less severe hair loss.

This case report describes a 29-year-old Japanese man with follicular mucinosis, suggesting nestin-positive, multipotent hair follicle stem cells may be involved in reticular epithelial degeneration of the outer root sheath.

In this study, DOP treatment improved hair regrowth in androgenetic alopecia by altering local steroid metabolism and follicular morphology.

This study reports that a novel ketoconazole-loaded microneedle array significantly enhances drug delivery and retention in the skin, demonstrating improved hair growth in animal models, suggesting a promising treatment for androgenic alopecia that addresses current topical therapies' limitations.
