This study observed that DMSO-modified liposomes enhanced the topical delivery of finasteride, improving hair follicle density and growth phase ratio in a rat model of testosterone-induced alopecia.

In this study, PRP after FUE increased hair density and length in men with androgenetic alopecia, with no scalp redness reported beyond the first month.

This study evaluated the use of Jet Peel technology, a non-invasive hydroporation method, in treating androgenetic and telogen effluvium alopecia, finding improvements in hair growth and thickness, and a reduction in associated scalp conditions.

In this systematic review, researchers found that nanotopical systems like nanoparticles and liposomes significantly improved hair density, thickness, and follicular regeneration markers in alopecia treatment, sometimes surpassing traditional therapies like topical minoxidil, though methodological limitations remain such as insufficient long-term clinical trials.

This report provides the first microscopic description of pachyonychia congenita-associated alopecia, identifying a combination of histological features that might be unique to this condition.

This study suggests that seborrhoeic folliculitis may represent a unique form of cicatricial alopecia, linking chronic scalp dermatitis-folliculitis with low-grade inflammatory fibrosing 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 study evaluated salmon-derived exosomes combined with microneedling as a treatment for androgenetic alopecia, reporting significant improvements in hair density, follicular health, and scalp microenvironment, with no serious adverse events observed in the 20 patients after 12 weeks.

In this review, recent innovations in hair transplantation, such as AI-assisted graft selection, robotic systems, stem cell therapy, and advanced drug delivery techniques, are reported to enhance hair density and thickness for more natural results and higher patient satisfaction by addressing limitations of traditional methods.

This study concluded that TrichoxidilTM positively affected hair growth by increasing growth factor expression and fibroblast proliferation, suggesting it may be a promising treatment for androgenetic alopecia.

This study reports that plasma rich in growth factors appeared to improve hair follicle regeneration and patient satisfaction in individuals with androgenetic alopecia, though further trials are needed.

This review discusses the potential of nanostructured lipid carriers to improve herbal treatments for alopecia and reports no new clinical results, highlighting the need for further clinical trials and safety data.

In this study, Eremochloa ophiuroides-derived fractions were found to significantly promote hair regrowth in a mouse model, demonstrating effects comparable to minoxidil and suggesting potential as natural hair growth agents through modulation of follicular activation markers and growth-regulatory factors.

This study reviewed clinical literature on telogen effluvium caused by COVID-19 and found that intense hair shedding predominantly affected women, typically developing two months post-infection and resolving within one to four months.

This letter to the editor by Walter P. Unger discusses topics related to hair transplantation and reports no new research findings.

Hair restoration surgery is improving, with less painful techniques like FUE and robotic systems, but they can be costly and require training.

This study found that intra-operative platelet-rich plasma therapy may enhance hair regrowth, increase graft density, and activate dormant follicles more effectively than normal saline in follicular unit extraction hair transplant patients.

In this comprehensive review, researchers reported that macromolecules like type I collagen, keratin, and ceramides enhance hair health by improving follicular function and increasing hair density, strength, shine, and resilience, as shown in various in vitro, animal, and human studies.

This source reports that hair surgeons can now regularly and significantly reduce damage to existing hair follicles in early-stage pattern baldness patients, helping preserve hair during treatment with finasteride or minoxidil.

This study explored the effects of TTFE on male androgenic alopecia, finding that topical application increased hair density, follicular diameter, and scalp hydration while reducing water loss and sebum production in a 12-week trial.

This study found that combining hair transplantation with PRP therapy resulted in better quality and increased growth of new hair, while also speeding up skin healing and reducing hair loss post-transplant.

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

This study found that human umbilical cord mesenchymal stem cells (hUCMSCs) promoted hair regeneration in androgenetic alopecia model mice by activating Wnt/β-catenin signaling, enhancing hair follicle stem cell proliferation, and reducing dermal papilla cell apoptosis.

This study found that stem cell therapy before follicular unit extraction may improve hair restoration outcomes on scarred scalp tissue.

This article discusses specific concerns in hair transplantation for East Asians due to their unique facial and hair characteristics and emphasizes the techniques required to minimize follicle damage during FUE procedures.

This study evaluated the safety and efficacy of Bio-Pulsed avian mesenchymal stem cell-derived small extracellular vesicles when applied topically, finding significant improvements in hair growth, skin rejuvenation, and regenerative microRNA presence among 60 human participants without adverse events.

This study observed that white hair can create an optical illusion of increased scalp visibility, potentially misleading clinical evaluations of hair loss and complicating hair transplantation planning, and identified five core dyeing strategies to address this phenomenon.

This review discusses techniques for harvesting follicular units, medical treatments for androgenetic alopecia, and potential future advancements in hair restoration therapy, but it reports no new clinical results.

This study found that adding Triamcinolone to the local anesthetic solution and administering PRP sessions significantly improved hair transplantation outcomes, with gene expression indicating SRD5A2's role in transplant success.

This study highlights IGF-1's role in promoting hair follicle proliferation, vascularization, and growth, suggesting its potential as a treatment target for hair loss disorders like androgenetic alopecia, though more research on delivery methods and long-term effects is needed.
