This article reviews common scalp and hair disorders in children and adolescents and outlines diagnostic approaches, but reports no new clinical findings.

This review discusses various hair disorders associated with autoimmune connective tissue diseases, particularly lupus erythematosus, and highlights diagnostic approaches but reports no new clinical results.

Up to 50% of scalp hair can be lost before it appears thin, and treatment is only needed for hair loss caused by diseases or deficiencies.

This study suggests that diffuse alopecia areata initially involves an intense inflammatory attack during the anagen phase, progressing through different hair cycle stages with specific shedding patterns.

Hinokitiol and pantothenylethylether in hair products can cause strong allergic reactions.

In this phase 2 trial, STS01 1% significantly improved hair regrowth in patients with mild to moderate patchy alopecia areata compared to placebo, with a manageable skin irritation side effect profile.

This case report from Dr Batra’s Homeopathy Clinic documents a middle-aged man with trichotillomania who showed marked improvement in hair regrowth and reduced hair pulling after receiving a classical homeopathic treatment for seven months.

This study examined the sensitization potential of common hair care products and found that certain ingredients, like cobalt chloride and nickel sulfate, frequently cause allergic reactions in individuals with hair diseases, providing essential insights for personalized treatment strategies.

This study found that elevated STAT5 levels are linked to improved hair-inducing capabilities in human dermal papilla cells, and reducing STAT5 impairs hair follicle induction.

Hair loss is common, with different types affecting people due to genetics, stress, or autoimmune issues.

Hair loss is common and varies by type, with androgenetic alopecia being the most prevalent.

This case report highlights that CCCA can present with multifocal patchy hair loss in younger men of African descent, suggesting the need for careful evaluation when diagnosing atypical alopecia patterns.

In this study, 61.4% of females infected with COVID-19 reported hair problems, such as telogen effluvium and increased gray hair, with most cases starting or worsening post-infection as confirmed by trichoscopy.

This study found that trichoscopy is a valuable diagnostic tool for identifying hair loss patterns in women and can help avoid scalp biopsies in unclear cases.

This study observed that physical examinations of hair and scalp changes, such as texture and color alteration, can help predict zinc deficiency severity among children with hair abnormalities.

The document concludes that hair loss in women is complex, often linked to aging, health conditions, and nutritional deficiencies, and emotional impacts should not be underestimated.

Hair damage shows as fragility, dullness, and discoloration, varies by ethnicity, and is worsened by cosmetic procedures and diseases.

This study found that Betamethasone was more effective than Tacrolimus and soft paraffin in promoting hair regrowth in patients with mild to moderate patchy alopecia areata.

This review highlights a case of cross sensitization to dyes from temporary henna tattoos and stresses the need for public awareness on the risks associated with these tattoos.

In this study, repressing β-catenin/Lef1 signalling in mouse epidermis led to progressive hair loss, dermal cysts, and spontaneous skin tumors with sebaceous differentiation, indicating altered keratinocyte differentiation and potential tumourigenic processes.

This study found that adverse reactions to para-phenylenediamine in hair dye, including severe allergic contact dermatitis, may be more common than currently reported and often misdiagnosed.

The authors concluded that some patients clinically diagnosed with telogen effluvium may actually have alopecia areata incognita, suggested by the presence of dystrophic hairs and development of alopecia patches.

This study found that a novel ECM patch combining human fibroblast-derived matrix and PVA hydrogel, seeded with human mesenchymal stem cells, significantly improved wound healing and tissue regeneration in a mouse model.

This pilot study found that azelaic acid treatment for patchy alopecia areata had similar hair regrowth results as anthralin, suggesting it may be an effective topical therapy.

This research found that a biodegradable fibrous membrane incorporating fibroblast-derived ECM accelerated wound healing and improved neovascularization in a mouse model.

This study analyzed patch test results to identify allergens causing scalp contact dermatitis, finding nickel, cobalt, and balsam of Peru among the most common in the patient population.

This article reports a case of neurodermatitis where a combination of intralesional steroids, oral doxepin, and psychotherapy resulted in complete symptom remission and hair regrowth, highlighting the importance of addressing emotional factors in treatment.

This study developed an antimicrobial microneedle patch for delivering apoptotic vesicles to treat infected wounds, which was found to effectively reduce bacterial growth and accelerate scarless healing, including the rapid formation of mature hair follicles in just 8 days, a previously unreported early outcome.

In this study, researchers developed a chemical cocktail and suspension culture method to transform human dermal fibroblasts into dermal papilla-like cells capable of inducing hair follicle formation in vitro and in vivo.

This study describes the process of isolating and analyzing multipotent stem cells from mouse hair follicles for potential use in tissue engineering and regenerative medicine.
