In this case study, a 38-year-old woman with female androgenetic alopecia experienced increased hair density and improved hair structure following ten microneedle mesotherapy sessions combined with saw palmetto supplementation, without adverse effects.

In this study, researchers synthesized the fictional compound 1-hydroxyindole and discovered its potential medical applications, including anti-aging properties, itch relief for atopic dermatitis, and as a stronger treatment for dementia compared to cilostazol. Additionally, they found that 1-methoxyindole derivatives function as anticancer agents in diets.

This study identified flavonoids and phytosterols in a medicated cosmetic cream developed for androgenic alopecia and proposed methods for their identification and quantification.

This study demonstrated that optical coherence tomography effectively detects significant changes in hair structure caused by steroid treatment, suggesting its potential use in doping control and clinical therapy monitoring.

This study found that the gel form of substance Y led to more hair follicles in the growth phase than 2% minoxidil solution when applied for alopecia treatment in mice.

This review discusses the neurobiology and proposed mechanisms of scalp itch, but it does not report new clinical findings, highlighting the need for further research in this area.

This review discusses the development and application of multiphoton microscopy in dermatology, highlighting its advantages and potential future research directions without reporting new clinical results.

This study found that acute stress in rats inhibits hair growth, likely through increased cortisol levels and activation of the substance P-mast cell pathway.

This study investigated peptidergic nerve fibers in sinus hair follicles of various mammals and found that CGRP fibers were more densely distributed than SP fibers across different regions of the follicles.

This study found that botulinum toxin type A injections in stressed mice appeared to normalize hair follicle regeneration cycles and reduced stress-related hair loss indicators.

This study links scalp pruritus in lichen planopilaris and its variants to the inflammation-induced release of substance P and calcitonin gene-related peptide by sensory nerves around hair follicle inflammation sites.

This study found that targeting the molecule Midkine may reduce pain and itching in keloid patients by inhibiting specific Schwann cell activities contributing to these symptoms.

Certain substances can help skin cells become anti-inflammatory, aiding in tissue repair.

In this study, Rhododendron molle extract increased hair follicle length and growth factors while reducing mast cell and substance P expression in stressed mice, suggesting potential benefits for hair growth.

This review discusses recent advances in understanding acne pathobiology, highlighting the potential for developing new customized therapies, but it reports no new clinical findings.

This study found that adult trichotillomania is a chronic disorder often linked with high psychiatric comorbidity and suggests the tension-reduction criterion in diagnoses might be too restrictive.

This review discusses the brain-skin connection, the skin's role in stress response, and highlights unmet challenges in understanding stress-induced skin inflammation but reports no new experimental findings.

In this study, researchers found that substance P triggered premature catagen development and immune changes in human scalp hair follicles, providing a possible biological link between stress and hair loss conditions like telogen effluvium and alopecia areata.

This review discusses immune privilege in anagen hair follicles and its collapse in alopecia areata, emphasizing the importance of restoring this function for effective management and disease relapse prevention.

This study provides evidence that psychoemotional stress inhibits hair growth in mice by affecting the brain-hair follicle axis, with specific neuropeptides and treatments modulating this effect.

This study found that stress increases the number of peptidergic nerve fibers and mast cell activity in mouse skin, suggesting a significant neuro-immune interaction under stress.

This study found that substance P and calcitonin-gene-related peptide have different roles in regulating hair growth in mice, with substance P promoting anagen progression and calcitonin-gene-related peptide inhibiting it.

This review discusses neural mechanisms involved in hair growth control, focusing on piloneural interactions, but reports no clinical findings; the authors suggest further exploration for managing hair growth disorders.

In this study, naked mole-rats demonstrated unique skin and hair follicle innervation features compared to other species, suggesting adaptations to their subterranean environment and poikilothermy.

This article proposes that alopecia areata may be caused by immune attacks on hair follicles after an immune privilege collapse, suggesting new therapeutic approaches targeting this immune response pattern.

This study found that premature hair loss due to stress does not occur in NK-1 receptor knockout or mast cell deficient mice, suggesting a key role for neurokinin substance P and mast cell interaction in stress-related hair follicle changes.

This research highlights that psychological stress can adversely affect hair growth in mice, implicating potential pathways that may be relevant in understanding stress-induced hair growth inhibition in humans.

This study in mice demonstrated that stress or nerve growth factor injection increases sensory neuron activity related to skin innervation, suggesting a strong connection between stress perception and neurogenic skin inflammation.

Stress can cause hair loss and skin issues by affecting hair growth cycles.

Capsaicin cream quickly relieved itching in two patients with brachioradial pruritus.
