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 dissertation found that hair follicle transplantation promoted wound healing in mice by enhancing wound re-epithelialization and increasing nerve density in the granulation tissue.

In this study, 77% of androgenetic alopecia patients showed hair regrowth with minoxidil treatment, while lower SULT1A1 enzyme activity, ATP concentration, and initial hair density were identified as negative prognostic factors for treatment response.

This review found that platelet-rich plasma was effective in increasing hair follicle cell activity and capillary density in alopecia treatment, with enhanced outcomes when combined with microneedling or minoxidil.

This meta-analysis found that PRP monotherapy improved hair density in androgenetic alopecia patients but did not affect hair diameter, with stronger effects observed in male subjects.

This review compares mesotherapy and PRP for hair loss but reports no new clinical results; the authors highlight the need to understand their differences for optimal treatment choices.

This pilot study suggests that platelet-rich plasma may be a promising treatment for chronic telogen effluvium with good safety, and cost-effective preparation methods may be reliable alternatives to more expensive ones.

This study reported that newly developed RADA16-I peptide hybrids, with active motifs like GHK and KGHK, demonstrated improved wound healing in a mouse skin injury model without cytotoxicity, suggesting they might be effective scaffolds for tissue engineering and regeneration.

In this study, 32 healthy adults with hair fall complaints applied a hair serum daily for 60 days, resulting in statistically significant improvements in hair growth rate, thickness, and density, without any reported adverse events.

In this study, EFH-SLM cream demonstrated greater efficiency in reducing hair density compared to plain EFH cream in Swiss albino female mice, with significantly less skin irritation and inflammation observed, suggesting improved permeability and effectiveness of EFH when using the new cream formulation.

This report highlights that 49.4% of U.S. patients with skin issues use complementary and alternative medicine (CAM), with 6% leveraging it specifically for their skin conditions, including treatments like herbal, vitamin, and mineral supplementation for alopecia.

This review discusses the strengths and weaknesses of existing studies on complex dietary supplements for hair loss, emphasizing the need for valid measurement methods like TrichoScale® to quantify effectiveness; it reports no new results.

In this study, a single application of autologous cellular micrografts showed short-term favorable responses in up to two-thirds of patients with androgenetic alopecia.

This review discusses the potential efficacy and applications of platelet-rich plasma in dermatology, highlighting its use in various skin conditions but reporting no new clinical results; the authors call for standardization of preparation and treatment methods.

This study found that vitamin supplementation may not significantly improve hair density or diameter in patients with non-scarring alopecia, questioning the utility of laboratory testing for vitamin deficiencies.

This study observed that while both minoxidil and botanically-derived 5-alpha reductase inhibitors significantly increased hair count and diameter in women with female pattern hair loss, minoxidil was more effective, especially for greater hair diameter increases, but had more troublesome side effects.

In this animal study, applying a combination of inositol-stabilized arginine silicate complex and magnesium biotinate promoted hair growth but not nail growth.

In this case report, a 41-year-old man with moderate androgenic alopecia showed an increase in hair density and improvements in hair characteristics after using Zimmer aqueous spray containing Zimmer herbal extract powder for 3 months, suggesting its potential as an alternative treatment for hair loss.

This study found that a new propylene glycol-free 5% minoxidil lotion demonstrated good clinical efficacy and very good cosmetic acceptability and tolerability after six months of use in patients with androgenetic alopecia, showing results comparable to traditional formulations containing propylene glycol.

In this study, researchers observed that a polyherbal ointment made from specific plant extracts significantly promoted hair growth in rats compared to ointments with single extracts, possibly due to the presence of flavonoids and tannins.

In this prospective study, individuals with androgenetic alopecia using a home-use low-level laser therapy helmet for 48 weeks experienced significant increases in hair density and thickness, with reported improvements consistent across sexes and no device-related adverse events.

This review highlights that robotic hair transplantation reliably and efficiently extracts follicular units with transection rates comparable to manual methods, potentially allowing more physicians to offer hair restoration without needing additional staff, and notes ongoing software advancements that could enhance aesthetic results.

This study found that FUE megasession with a specific surgical design is an effective and satisfactory treatment for Asian patients with high-grade male androgenetic alopecia, achieving natural hair density and high patient and doctor satisfaction, with minimal side effects.

This study found a significant association between COVID-19 hospitalizations and acute telogen effluvium in Egyptian women, emphasizing the importance of considering recent COVID-19 infections when evaluating hair loss in this population.

This study observed that Egyptian women with a history of COVID-19 infection frequently experienced telogen effluvium, indicating the importance of considering COVID-19 history in patients presenting with hair loss.

This study found that Iraqi male bodybuilders abusing anabolic androgenic steroids experienced significant changes in sex hormones, liver and kidney function, and lipid profiles compared to non-AAS-using controls.

Skin problems like acne, dry skin, and nail and hair changes are common in patients taking EGFR inhibitors.

In this animal study, topical VEGF gel increased hair growth and thickness in Mesocricetus auratus, although it was not completely inert, highlighting the need for further toxicity confirmation.

This study found that platelet-rich plasma combined with topical minoxidil was more effective in increasing hair density for male-type baldness than either treatment alone.

In this study, premature hair graying in Indian patients under 25 was associated with low levels of serum ferritin, Vitamin B12, and high-density lipoprotein cholesterol.
