In this study, physiological levels of free T3 significantly enhanced the survival of human hair follicles in vitro.

This study found that normal human epidermis expresses TSH and may be an indirect target of TSH signaling, with expression regulated by endocrine controls of the hypothalamic-pituitary-thyroid axis.

This study found that applying supraphysiologic doses of topical T3 significantly accelerated wound healing in mice compared to a control vehicle, suggesting its potential as a cost-effective wound treatment.

HPT axis hormones boost mitochondrial function and growth in hair follicles, potentially aiding hair health.

This article emphasizes the importance of thyroid function monitoring and management in women, particularly for those planning pregnancy or postpartum, but reports no new clinical results.

The researchers reported that during early embryogenesis and larval development in Silurana tropicalis, inhibiting steroidogenic enzymes cyp19 and srd5beta affects genes related to thyroid and reproductive systems.

This study found that thyroid hormones T3 and T4 enhance keratin 15 promoter activity and stimulate CD200 expression in epithelial stem cells from human scalp hair follicles, affecting their growth and differentiation.

This study recommends limiting routine thyroid function screening to children with alopecia areata who have medical histories of Down syndrome, atopy, or family histories of thyroid disease.

In this study, alopecia areata was associated with thyroid autoimmunity but not islet autoimmunity, correlating with specific class II HLA haplotypes linked to various autoimmune diseases.

This study found that in male badgers, seasonal molting and hair growth are influenced by cycles of plasma testosterone and thyroxine, with hormones affecting the timing and progression of these processes.

This review discusses the potential therapeutic use of thyroid hormones on skin conditions, highlighting the need for further research but reporting no new experimental results.

This study identifies a mutation in the hairless gene that may impact thyroid receptor interaction, contributing to alopecia universalis congenita in an Arab Israeli patient.

This review discusses recent molecular biology advances in the human phenol sulfotransferase gene family and reports no new results; the authors highlight its relevance for studies of endogenous and xenobiotic metabolism.

This study demonstrated that thyroid hormone receptors play a crucial role in hair growth and skin health, as mice lacking these receptors showed impaired hair cycling and wound healing.

This study observed that chemically-induced intersex frogs displayed altered brain mRNA profiles, with finasteride increasing certain hormone-related gene expressions and fadrozole reducing aromatase activity without affecting gene transcript levels.

In this study, researchers found that Hashimoto's thyroiditis patients, despite being in euthyroid status, experienced more severe extrathyroidal symptoms compared to healthy controls, and elevated thyroid antibodies were linked to lower health-related quality of life and increased inflammation.

Hair loss is often linked to thyroid problems, especially in women and older people, and screening for thyroid issues is advised for those with hair loss.

This case report documents an instance of symptomatic hypothyroidism developing in a patient with papillary thyroid carcinoma after beginning treatment with orlistat.

This study found that mu-crystallin gene expression in mouse skin is highest during the anagen phase of hair development, suggesting its possible role in hair follicle growth.

This study observed that telogen effluvium was the most common form of acquired alopecia among females in a semiurban Indian population, with stress and chemical exposure as major exacerbating factors.

This study found that a thyroid hormone receptor ẞ subtype-selective thyromimetic was effective in promoting hair growth in mouse and monkey models when applied topically.

In this study, common skin manifestations in hypothyroidism patients included dry, coarse skin, pigmentary disorders, and telogen effluvium.

This study found that the synthetic thyroid hormone receptor modulator KB2115 significantly prolonged the growth phase of human hair follicles in culture without altering mitochondrial activity, suggesting potential as a safer hair loss treatment compared to traditional thyroid hormones.

This report describes two young women with severe psoriasis and alopecia universalis, highlighting the possible but unstudied association between alopecia areata and metabolic syndrome.

This study found that premature hair graying is strongly associated with a family history, Vitamin B12 deficiency, and hypothyroidism, with onset as early as 5 years in patients in Gurugram, India.

Higher thyroid hormone levels may be linked to certain types of polycystic ovary syndrome.

This study observed that direct exposure to androgens in Western clawed frogs differentially affects thyroid receptor and deiodinase gene expression in male and female tissues, offering insight into sex-specific metabolic pathway activation.

This case study reports an instance of adult-onset primary hypothyroidism with goiter in a cat, suggesting potential causes such as dietary iodine imbalance, chronic exposure to thyrotoxic substances, or a congenital form with late manifestation.

Some people with chronic hair loss may have thyroid autoimmunity.

This study found that long-term use of a home-use LED device for neck skin rejuvenation significantly improved wrinkle appearance and skin biophysical parameters without affecting thyroid function or morphology after 16 weeks of daily use.
