Skin and hair cells release serotonin and histamine naturally, which could help improve skin health.

This case report highlights that intradermal testing may be more effective than patch testing for diagnosing delayed hypersensitivity reactions to intralesional corticosteroids like triamcinolone acetonide.

This study found that hypaphorine alters cytoskeletal organization in Eucalyptus globulus root hairs, contributing to reduced root hair elongation by possibly disrupting vesicle delivery needed for growth.

This study found that tetracycline can adhere to hair follicle structures and disrupt cell metabolism, potentially damaging healthy human cells as well as pathogens.

This study isolated a bioactive peptide from Trapa japonica fruit and found that it may protect human dermal papilla cells from DHT-induced stress, suggesting potential for biomedical applications.

Thymic peptides can either promote or inhibit human hair growth.

This article reviews monilethrix, a rare genetic hair disorder causing brittle hair and alopecia, and emphasizes the need for clinical diagnosis and characteristic tricoscopic findings.

This case report details a 52-year-old man's successful hair regrowth following treatment with griseofulvin for Trichophyton tonsurans-induced scalp ringworm.

This study found that acid regulation of the TRPV3 channel can inhibit its function from outside the cell while facilitating it from inside, providing insights into skin barrier and disorder mechanisms related to tissue acidosis.

This study explored how modifying the 8-substituent of 8-bromobenzoquinolinone affects its selectivity in inhibiting both 5 alpha-reductase isozymes in the scalp.

The researchers reported two brothers with a new variant of X-linked trichothiodystrophy associated with an RNF113A gene mutation, highlighting features such as intellectual disability and growth failure, but without previously reported endocrinological or genital abnormalities, underlining the importance of genetic counseling for such variants.

This study reported that thymol-loaded nanoparticles showed promise as an antibiotic-free treatment for acne by effectively targeting the infection without disrupting healthy skin microbiota.

This review found that tea tree oil, especially terpinen-4-ol, may be the most effective treatment for Demodex-related diseases, but more research is needed to improve treatment efficacy and reduce side effects.

This case report described a 43-year-old male with trichotillomania, experiencing severe alopecia and an ulcerated plaque, who improved with a combination of antibiotic, antidepressant, and psychotherapy treatments, suggesting that these interventions may benefit individuals with psychiatric comorbidities linked to this condition.

Two women had skin reactions from a hair loss treatment and got better after stopping use.

This study reports two cases of alopecia areata that responded to the antihistamine fexofenadine.

This review presents analytical methods for estimating Thuja occidentalis in homeopathic mother tincture but reports no new clinical results, emphasizing its broad application in homeopathy.

This study found that patients with trichodynia associated with androgenetic alopecia had significantly higher levels of substance P in both tissue and serum compared to healthy controls, suggesting a potential role for this neurotransmitter in the condition's pathogenesis.

In this study on male rats, parachlorophenylalanine treatment induced hypersexual behavior and hair loss linked to increased social interaction but had no effect on brain serotonin when testosterone was used instead.

This article reviews trichotillomania, highlighting its prevalence, common treatment options, and challenges such as secrecy and delayed treatment, but reports no new clinical results.

This study found that a laboratory model using nude mice can produce human hair follicles with amino acid compositions resembling both normal and trichothiodystrophy-affected human scalp hair over extended periods.

This study found that abietic acid from pine resin more effectively inhibits testosterone 5α-reductase than several plant extracts, suggesting potential for treating androgen-dependent diseases.

This study concluded that THC and THCA incorporate into hair by a mechanism independent of hair pigmentation, likely influenced by indirect deposition via sebum and skin.

This review identifies several off-label uses of H-1 antihistamines in dermatology beyond itch and urticaria control, though the evidence is weak and further trials are needed.

This study found that laccase-assisted grafting of poly(tyrosine) onto wool materials improved shrinkage resistance and mechanical properties while causing minor decreases in crystallinity and thermal resistance, suggesting a potential "green" approach to enhance wool durability.

In this study, phenylthiocarbamide intake was associated with hair graying in rats, while switching to tap water led some rats to regain their original fur color, suggesting dietary factors influence pigmentation.

This study observed that vimentin and transthyretin proteins were more highly expressed in black sheep skins compared to white, suggesting their involvement in coat color formation.
