research Acne, the Skin Microbiome, and Antibiotic Treatment
Antibiotics can reduce acne but may lead to resistant bacteria, and understanding the skin's bacteria is important for treatment.
research Hair growth inhibition by psychoemotional stress: a mouse model for neural mechanisms in hair growth control
Stress can stop hair growth in mice, and treatments can reverse this effect.
research Physicochemical properties of pH-sensitive hydrogels based on hydroxyethyl cellulose–hyaluronic acid and for applications as transdermal delivery systems for skin lesions
The hydrogel with a 1:3 ratio of hydroxyethyl cellulose to hyaluronic acid is effective for delivering drugs through the skin to treat acne.
research Stress exposure modulates peptidergic innervation and degranulates mast cells in murine skin
Stress increases nerve fibers and immune cell activity in mouse skin, possibly worsening skin conditions.
research Hair-Cycle-Associated Remodeling of the Peptidergic Innervation of Murine Skin, and Hair Growth Modulation by Neuropeptides
Neuropeptides affect hair growth, with some speeding it up and others slowing it down.
research Somatosensory organization and behavior in naked mole‐rats: II. Peripheral structures, innervation, and selective lack of neuropeptides associated with thermoregulation and pain
Naked mole-rats have unique skin and hair nerve structures, lacking certain pain and temperature-related neuropeptides.
research Neural Mechanisms of Hair Growth Control
Nerves and chemicals in the body can affect hair growth and loss.
research Biology and Genetics of Hair
The document concludes that understanding the genes and pathways involved in hair growth is crucial for developing treatments for hair diseases.
research Trichoblastic Carcinoma (“Malignant Trichoblastoma”) with Lymphatic and Hematogenous Metastases
Long-standing benign tumors can become cancerous, especially in people with weakened immune systems.
research The Role of Hair Follicle Immune Privilege Collapse in Alopecia Areata: Status and Perspectives
Alopecia areata may be treated by restoring hair follicle immune privilege and adjusting immune responses.
research Mast cell deficient and neurokinin-1 receptor knockout mice are protected from stress-induced hair growth inhibition
Certain mice without specific receptors or mast cells don't lose hair from stress.
research Mechanistic target of rapamycin (mTOR) expression is increased in acne patients' skin
Acne patients have higher levels of mTOR in their skin, which could be linked to future metabolic disease.
research Neuroendocrine Perspectives in Alopecia Areata: Does Stress Play a Role?
Stress might contribute to hair loss in alopecia areata.
research Pathways to inflammation: acne pathophysiology
Acne is caused by genetics, diet, hormones, and bacteria, with treatments not yet curative.
research Neuronal plasticity of the “brain–skin connection”: stress-triggered up-regulation of neuropeptides in dorsal root ganglia and skin via nerve growth factor-dependent pathways
Stress increases certain chemicals in the skin and nerves, which might worsen skin conditions.
research Comparison of Healthy and Dandruff Scalp Microbiome Reveals the Role of Commensals in Scalp Health
Certain bacteria and fungi are linked to healthy scalps and dandruff, suggesting that the scalp's microbial balance affects its health.
research Anti-Acne Agents Attenuate FGFR2 Signal Transduction in Acne
Anti-acne medications may work by reducing the activity of a protein involved in acne development.
research Metal-Chelation-Assisted Deposition of Polydopamine on Human Hair: A Ready-to-Use Eumelanin-Based Hair Dyeing Methodology
Polydopamine is a safe, effective, and permanent hair dye that turns gray hair black in one hour.
research Proteome Analysis of Human Sebaceous Follicle Infundibula Extracted from Healthy and Acne-Affected Skin
Acne-affected skin has more inflammation-related proteins and bacteria than healthy skin.
research The itchy scalp - scratching for an explanation
Scalp itching is common and hard to diagnose due to the complex nerve structure of the scalp.
research Stress and the Hair Follicle
Stress can cause hair loss and skin issues by affecting hair growth cycles.
research Understanding the role of Propionibacterium acnes in acne vulgaris: The critical importance of skin sampling methodologies
Precise skin sampling is crucial to understand the role of P. acnes in acne.
research ACNE
Acne significantly affects mental health and quality of life, with research suggesting hormonal and genetic factors in its development and emphasizing early treatment to prevent scarring.
research Brachioradial pruritus: Treatment with topical capsaicin
Capsaicin cream quickly relieved itching in two patients with brachioradial pruritus.

A new model helps study acne and test treatments.
research An ultrastuctural study of hair fiber damage and restoration following treatment with permanent hair dye
Permanent hair dye damages hair but it mostly recovers after 8 weeks; using certain hair care products can help repair it.
research Pattern of tissue invasion by Propionibacterium acnes in acne vulgaris
The document concludes that advanced methods show the presence of P. acnes in acne lesions but do not prove it causes acne.
