Hair growth phase in mice weakens certain immune responses.

This study found that 17beta-estradiol enhanced allergy responses in certain age groups of female mice and inhibited thymus involution and regeneration after contact hypersensitivity.

This review discusses the use of contact hypersensitivity for alopecia areata and highlights its potential immunomodulatory benefits, but reports no new clinical findings.

The document concludes that various hypersensitivity diseases in horses can be diagnosed and treated with methods like immunotherapy and medication, and early aggressive treatment is crucial for severe diseases like equine cutaneous pythiosis.

This study highlights that homemade topical herbal preparations, although popular for their perceived safety, may lead to allergic reactions, notably with Mediterranean herbs, and advises cautious use, particularly for allergy-prone individuals.

This preliminary study observed that topical nitrogen mustard was beneficial for only 1 out of 6 patients with extensive alopecia areata, with 4 patients not completing the trial.

This study found that while ozonized olive oil inhibited swelling in a mouse model of hypersensitivity, it also induced inflammatory responses and hair loss with repeated skin application, indicating potential adverse effects.

This study found that engineered high-affinity soluble CD200R agonists, including ARQ-234, showed superior efficacy in reducing immune responses in various preclinical models of inflammatory conditions, suggesting potential as a therapeutic for atopic dermatitis and other related diseases.

This thesis found that inhibiting IL-17 and IL-23 improved chronic wound healing in obese, diabetic mice by promoting a pro-healing macrophage phenotype, while ST2 signaling was also necessary for effective wound healing.

This study reports that erythematous, infiltrated plaques can develop in patients receiving subcutaneous heparin therapy, indicating a possible delayed hypersensitivity reaction to heparin or its constituents.

Langerhans cells are crucial for skin immunity and allergic reactions.

In their review, the authors discussed the increasing issue of allergies to hair products, highlighting common allergens such as hair dyes and topical minoxidil, and outlined diagnostic methods and alternatives for those affected, particularly addressing higher risks among hairdressers due to professional exposure.

This study suggests that contact sensitizers may treat alopecia areata by expanding suppressor cells and interfering with antigen presentation to lymphocytes.

This study suggests that long-term treatment with the contact sensitizer SADBE in mice may reduce leucocyte traffic in alopecia areata through impaired leucocyte extravasation.

This study from a dermatology department found that patch test positivity for allergic contact dermatitis is lower in geriatric patients than in adults, likely due to age-related immune changes and reduced allergen exposure.

This report details a case study where a 40-year-old woman experienced allergic contact dermatitis and angioedema-like symptoms after using PPD-containing hair dye. Patch testing confirmed a positive reaction to PPD, highlighting the substance's potential to cause both T-cell and IgE-mediated hypersensitivity reactions.

This paper presents the first reported case of Acute Localized Exanthematous Pustulosis linked to topical minoxidil use, suggesting a contact-induced hypersensitivity reaction as a potential mechanism.

The journal emphasizes the importance of combining basic and clinical science to improve health.

ANp63 is crucial for skin integrity, new filaggrin gene mutations link to eczema, hair can regrow from non-stem cells, sunburns are increasing, and glucocorticoids help treat skin allergies by affecting immune cells.

In this study, tazarotene 0.1% gel showed greater efficacy than tretinoin 0.025% gel in reducing acne lesions and demonstrated similar efficacy to adapalene 0.1% gel when used less frequently.

Avoiding dyed wigs and clothing improved severe allergic reactions in a woman treated with diphencyprone.

This review discusses the use of contact sensitizers for topical immunotherapy in dermatological conditions such as alopecia areata and viral warts, but it reports no new clinical findings.

This case report documents the development of vitiligo-like lesions in a patient with autoimmune thyroiditis following the use of topical squaric acid dibutylester for alopecia.

This article describes cases of allergic contact dermatitis triggered by minoxidil but provides no new clinical findings.

In this study, patients with scalp seborrheic dermatitis exhibited distinct patterns of allergen sensitization tied to symptoms, impaired skin barrier, and altered microbiota, emphasizing the need to consider allergen exposure, barrier status, and microbial balance when interpreting patch test results.

This review summarizes current evidence on the use of contact immunotherapy, excluding alopecia areata, for various skin diseases, discussing its safety, efficacy, and the underlying mechanisms as reported from studies in the PubMed database.

Avoiding certain fragrances improved the man's skin condition.

Glycerin in hand cream can cause allergic skin reactions.

Minoxidil can cause pustular allergic reactions on skin.
