This study reported that microneedle-assisted delivery of PEGylated recombinant human fusion collagen significantly improved hair regrowth and density in an androgenetic alopecia mouse model and in a small clinical trial with AGA patients, suggesting potential efficacy and safety for this treatment approach.

This source highlights the utility of cationic polymers in haircare products for protecting against hair damage from chemical treatments and grooming, and describes how microfluorometry can measure polymer deposition and penetration on hair fibers.

A treatment called Cellcurin, combined with microneedling, significantly increased hair density and diameter in patients with hair loss.

This study found that a novel effervescent formulation significantly increased minoxidil sulphate accumulation in hair follicles and skin compared to a standard minoxidil solution.

In a clinical phase I/IIa study, subcutaneous injections of the peptide FOL-005 increased hair growth by 8% and were safe for treating alopecia.

Once-daily 5% minoxidil foam increases hair regrowth and density in women with hair loss, but not as effectively as twice-daily 2% minoxidil solution, though it's safer and more convenient.

This study found that early intervention and treatment with intralesional triamcinolone acetonide may stabilize hairline recession in patients with frontal fibrosing alopecia, although further research is needed for definitive treatment guidelines.

In this study, researchers developed a multilayered gel bead culture model using a microgel-spotting device, successfully mimicking the early development of skin appendages and supporting in vitro hair follicle regeneration with structures resembling native hair follicles.

This study developed granular hydrogels with reversible interparticle cross-linking, finding they offer high mechanical stability and enhance cell recruitment, making them promising for injectable and 3D printable scaffolds in tissue engineering and therapeutic delivery.

In this study, quercetin nanocrystals stabilized with glycyrrhizic acid were developed as a new treatment strategy for androgenetic alopecia, which significantly reduced DHT levels and improved hair regrowth in a mouse model, indicating synergistic potential for clinical application.

In this study, researchers found that a cold atmospheric plasma-activated hydrogel containing interleukin-2 significantly enhanced hair regeneration in a depilated mouse model, promoting larger hair follicles and faster hair growth phase transition, suggesting it as a potential treatment for hair loss.

This study found that treatment with human foreskin fibroblast conditioned medium improved both objective measures like hair density and subjective satisfaction in patients with androgenetic alopecia.

In this study, researchers found that a nanoparticle gel derived from Astragalus polysaccharides improved wound healing significantly more than a Gold-Silver nanocomposite gel and untreated controls, with better wound closure observed by the 15th day.

FOL-005 peptide may help treat excessive hair growth safely.

In this study, researchers created a hydrogel that reduces oxidative stress and releases a pro-angiogenic drug in response to enzyme activity, which accelerated healing and improved tissue regeneration in chronic diabetic wounds during in vivo experiments.

This study found that persistent significant alopecia was a common side effect following FEC-docetaxel chemotherapy, with a 33.4% global incidence, highlighting the need for awareness and potential preventative measures like cooling caps during treatment.

This study found that using a PEG-400/oleic acid mixture as an optical clearing agent enhanced the detection depth of particles in skin without causing dehydration, based on tests in rats and further testing in vivo.

This study found that an injectable hair material showed good biocompatibility in micropigs and effectively promoted dermal thickening, suggesting its potential as a new soft tissue filler.

This study concluded that an adapalene nanohydrogel containing Tween-80 could be a promising and stable topical treatment option for acne vulgaris due to enhanced skin permeability and stability compared to other formulations.

This study found that a single ablative fractional laser treatment significantly reduced hedgehog pathway gene expression in microscopic murine basal cell carcinomas, nearly matching the effects of repeated topical vismodegib applications.

This study found that methylcellulose-based hydrogels can effectively deliver growth hormone through the skin, with albumin increasing the hormone's permeation to 93% in simulated in vivo conditions.

This study introduced a novel nonsteroidal androgen receptor antagonist that effectively controls sebum production in the golden Syrian hamster ear model through targeted follicular delivery.

This case report describes a unique presentation of frontal fibrosing alopecia characterized by a hair loss pattern that resembles the Greek letter upsilon, supported by trichoscopic and histological findings.

Hair gels may cause split ends in children.

This study investigated the effects of heat-treated Limosilactobacillus fermentum LM1020 on hair growth and reported increased hair density, improved cellular activity, and beneficial scalp microbiota changes in patients with androgenetic alopecia over 24 weeks.

In this study, researchers reported that a keratinocyte growth factor-Ig fusion protein could specifically detect and localize KGFRs in epithelial tissues, suggesting a method for histochemical detection of growth factor receptors.
