Microneedle roller therapy can help hair grow.

This study analyzed the phytochemical content of two Portulaca species and found that extracts from Portulaca oleracea L. and Portulaca grandiflora H. demonstrated suitable characteristics for hair tonic formulations, meeting Indonesian National Standards for cosmetic products.

This study validated the differential stripping technique on hairless rat skin and found that the P-08–016 formulation delivered more finasteride to the epidermis and appendages compared to P-10–008.

This review highlights the potential of microneedles as a pediatric-friendly method for delivering proteins, vaccines, and diagnostics transdermally, noting their ability to penetrate the skin's barrier and suggesting future applications in other parts of the body.

This review highlights the application of microneedle technology as a promising advancement in psoriasis management, focusing on its roles in enhanced transdermal drug delivery and minimally invasive biomarker monitoring, while also discussing current challenges and future research directions.

This review compiles patents for nanoparticulate drug delivery systems, discussing preparation methods, therapeutic applications, and commercialization, but reports no new experimental results.

The researchers in this experimental study developed a thermodynamic model using the Peng-Robinson equation of state to optimize gas antisolvent system conditions for controlling finasteride particle size, aiming to reduce experimental trials and precisely identify precipitation pressures across different temperatures.

In this study, using an ex vivo porcine skin model, researchers found that a 4% nanoparticle concentration significantly enhanced the transport of fluorescein sodium into hair follicles compared to a 2% concentration, while higher concentrations did not further increase penetration depth.

This study concluded that the Box-Behnken experimental design effectively optimizes the size of finasteride nano-emulsions by assessing the impact of various experimental factors.

In this study, topical nitroglycerine spray successfully prevented impending necrosis in 94% of hair transplant cases showing signs of vascular distress.

This study confirmed that the novel solid lipid microparticle formulation of adapalene demonstrated follicular penetration potential and targeted particle erosion in sebum in in vitro tests.

This study found that a caffeine-containing shampoo penetrated deeply into hair follicles in just two minutes and remained there for up to 48 hours, even after washing.

This study found that a herbal spray for treating bovine dermatophytosis was safe and economical, though conventional antifungal therapy had a higher cure rate.

This study developed a novel, 3D-printed dissolving microneedle system for delivering minoxidil to treat hair loss, which showed pH-triggered drug release and enhanced hair regrowth in an alopecia mouse model, offering a potentially sustainable and safe transdermal therapy option.

This article reviews the potential of nanoparticles for drug delivery through the skin barrier and highlights the need for further research on solid nanoparticles, as they lack commercial development for this purpose.

This study found that combining needle-free intradermal minoxidil delivery with standard topical minoxidil therapy improved early hair growth parameters and satisfaction in women with early-stage female pattern hair loss compared to topical therapy alone, with no serious adverse events reported over the 10-week period.

This study found that coated microneedles promoted drug release effectively, comparable to marketed minoxidil solutions, with stable performance over 30 days at high temperatures.

This study found that finasteride delivered through dissolving microneedles enhanced skin drug permeation compared to films, suggesting potential for improved androgenetic alopecia treatment with fewer side effects.

The human hair follicle can store topical compounds and be targeted for drug delivery with minimal side effects.

This study developed and tested continuous implanters for dermal papilla cell aggregates, finding that the bar-cartridge type implanter is the most effective design for continuous cell implantation in androgenetic alopecia research.

This case report describes subcutaneous emphysema in a patient's forearm as a rare complication of liquid nitrogen spray used on hypertrophic actinic keratosis, resolving spontaneously within a day.

This study suggests that using particle-bound antiseptics may provide more effective and longer-lasting skin antisepsis compared to their non-particulate forms.

In this study, a hair tonic formulation with bean leaf juice increased hair growth in male rabbits, with concentration-dependent improvements in hair length and weight compared to a control.
