This study found that a nanoemulsion containing perfluorooctyl bromide effectively increased oxygen levels in an anoxic environment, enhancing hair dermal papilla cell growth and significantly promoting hair organ elongation.

This study found that sensitive scalp is characterized by increased pH levels, redness, altered sebum composition, and a disrupted microbiome, suggesting these features could inform treatment approaches.

This study observed that mice lacking epidermal HSD11b1 had increased non-histaminergic itch and changes in skin nerve fibers, potentially linked to higher TSLP expression.

This study found that brain-derived nerve factor protein expression was significantly increased in balding scalp samples from men with androgenetic alopecia, suggesting it may play a role in hair follicle regulation.

This study found that low-dose oral minoxidil (≤5 mg/day) effectively increased hair number and diameter in men and women with androgenetic alopecia, and was generally well-tolerated with mostly mild adverse effects, although serious complications were rare and associated mainly with pre-existing heart conditions.

This retrospective study found that treatment with autologous plasma rich in growth factors increased hair density and improved hair follicle health in patients with androgenetic alopecia, with no reported adverse effects.

This study found that minoxidil pretreatment in rat skin flaps enhanced angiogenesis and increased flap survival compared to untreated flaps, but was less effective at reducing necrosis than surgical delay.

This study reported that autologous whole fat injection in the scalp considerably increased hair growth in patients with androgenetic alopecia.

This study found that a hair tonic containing 10% mesenchymal stem cell secretome significantly increased hair density in volunteers with alopecia after eight weeks, suggesting its potential as an effective treatment option for hair growth stimulation.

This study found that applying benzyl nicotinate on open hair follicles led to a significant increase in blood flow, highlighting the role of the follicular pathway in epidermal penetration.

This review indicates that estrogen loss during menopause significantly impacts skin health, while estrogen treatment may increase skin collagen, thickness, and elasticity, though effects on other skin characteristics are inconsistent.

In this study using a mouse model, the researchers found that platelet-rich plasma significantly increased the number of newly formed hair follicles and decreased the time for hair formation compared to no treatment.

This study found that C. obtusa oils promoted hair growth in shaved mice and increased the expression of a hair growth regulator, VEGF, in a cell line.

In this study, subdermal platelet-rich plasma injections significantly increased hair count and shaft caliber in individuals with androgenetic alopecia, with monthly treatments potentially offering greater benefits.

This study found that keratinocyte stem/progenitor cell-conditioned medium significantly enhanced hair growth in mice and increased the proliferation of human hair follicle cells.

This study found that a higher potassium diet in lysine-deficient rats partially protected against hair loss and increased liver fat, suggesting these rats require more potassium.

This study reports that γ-ray exposure in rats led to dermal endothelial proliferation, new vessel formation around hair follicles, and increased inflammatory markers, suggesting possible early stimulatory effects on hair growth.

In this study, researchers evaluated the efficacy of a collagen booster used alongside CO2 fractional laser treatment for skin aging, finding that the combination treatment affected the vascularization and healing process of the skin on a healthy adult's forearm.

This study found that heart-inspired hollow hydrogel-based scaffolds enhanced regenerative capability in osteoporotic bone defects and increased cell number when using a mechanical-assisted post-bioprinting strategy.

This study analyzed 853 articles to reveal that research on silica-based nanobiomaterials in regenerative medicine has rapidly increased, with distinct regional differences in impact and emerging focus areas in drug delivery and wound healing.

In this follow-up study, participants with severe androgenic/estrogenic alopecia showed increased hair growth 10 months after ending vacuum therapy and cosmetic emulsion treatment, highlighting the therapies' potential effectiveness.

This study found that minoxidil stimulates hair follicle growth by promoting dermal papilla cell survival and activating ERK and Akt pathways, which leads to increased proliferation and reduced cell death.

This review discusses the role of pharmacological sciences in advancing regenerative medicine technologies but reports no new experimental findings; the authors advocate for increased pharmacologist involvement to drive innovations.

In this study, patients receiving adipose-derived stromal vascular cell transplantation for alopecia areata experienced significant hair regeneration, increased growth, and improved hair quality after 3 and 6 months, indicating potential efficacy of this stem cell-based therapy for hair loss.

In this randomized clinical trial, the authors reported that adipose-derived stem cell constituent extract topical solution increased hair density and thickness in patients with androgenetic alopecia over 16 weeks compared to placebo.

This study found that combining micro-needling, low-level laser therapy, and autologous non-activated platelet-rich plasma increased hair density in patients with androgenic alopecia over the treatment period.

In this study, applying FGF-2-containing dalteparin/protamine nanoparticles to the scalp was associated with a significant increase in hair diameter over six months among participants with thin hair.

This review summarizes the characteristics of the peri-malignant melanoma stroma, indicating its potential role in early dermal metastatic migration and increased metastasis risk.

In this study, extracts from three Polynesian plants—Bidens pilosa, Calophyllum inophyllum, and Fagraea berteroana—were found to increase dermal papilla cell proliferation and modulate hair growth-related gene expression, suggesting potential for stimulating hair growth.

This study observed that topical application of maslinic acid stimulated hair growth in mice comparably to minoxidil, possibly through the Wnt/β-catenin pathway and involving ciliary gene activity, highlighting increased levels of trichogenic gene expression and protein levels.
