This study found that Hex gene expression patterns in chick embryo dorsal skin during feather bud development suggest a significant role in initiating feather morphogenesis.

This review discusses the role of the CRH–ACTH–cortisol axis in skin function and its potential link to stress-related skin and hair conditions, and reports no new experimental results.

This study suggests that hair loss was a metabolic adaptation allowing hominids to evolve larger brains by alleviating dietary restrictions on essential amino acids for hair and brain development.

The authors suggest that tooth, dermal scale, epidermal scale, feather, and hair evolved in parallel from a shared placode/dermal cell unit in an early vertebrate gnathostome with odontodes, around 420 million years ago.

Diphenyl ethers can potentially reduce excess oil production when applied on the skin, helping treat conditions like acne.

This study suggests that stress-associated hair loss may occur due to increased androgen receptor expression and activity induced by dexamethasone in human and mouse dermal papilla cells.

"D-CHRAMPS syndrome" is a newly identified condition with multiple severe symptoms.

This study suggests that chicken and alligator scales evolved independently through convergent evolution rather than sharing a common origin with avian feathers.

This proposal presents a standardized system for naming areas of the balding scalp to improve communication among hair restoration professionals, defining major regions and introducing new landmarks.

This study found that overexpression of Claudin 6 in mice led to incomplete epidermal formation and hair abnormalities, suggesting its crucial role in skin differentiation and hair follicle development.

TRH in hair follicles can influence hair color by increasing melanin.

In this study, researchers observed that rhino mice exhibit significant ductal hyperkeratinization in the meibomian gland, which may represent the first naturally occurring disorder of this gland in mice.

In this study, a rare case of a trichilemmal cyst in a 6-year-old's upper eyelid was observed; it was identified through histopathological examination after excision, highlighting the importance of considering trichilemmal cysts in atypical pediatric eyelid swellings.

This study found that reducing HDAC1 activity in the skin of mice led to defects in hair follicle structure and pigmentation, highlighting HDAC's role in skin and hair maintenance.

This study suggests that male pattern baldness is primarily caused by heat stress in the brain rather than DHT toxicity, and personal experiments with menthol cooling have shown significant reduction in hair loss.

This study found that Frizzled genes Fzd3 and Fzd6 are redundantly involved in controlling hair follicle polarity in mice, but operate through distinct mechanisms, highlighting their complex role in hair orientation.

This study found that 5 alpha-dihydrotestosterone increased pigmentation in dorsal spots and scrotal skin of prepubertal male Syrian hamsters, while estradiol decreased scrotal skin melanocytes and reversed androgen-induced pigmentation in costovertebral spots.

This study found that small proline-rich proteins modify the biomechanical properties of cornified cell envelopes in rodent forestomachs, potentially affecting the tissue's ability to withstand mechanical stress.

This study observed that hepatocyte-like cells in canine circumanal glands are distinct entities that develop from hair follicle sheaths and later appear within sebaceous glands, without forming typical exocrine ducts.

This research demonstrates that a temperature controllable medical chilling device using thermal electric cooling technology effectively maintains constant cell temperatures, potentially improving tissue viability during hair transplant procedures.

In this article, the authors compile various dermatological conditions that metaphorically reference animal-related visuals, such as "buffalo hump" in HIV-associated lipodystrophy or "leonine facies" in lepromatous leprosy, to enhance learning through mnemonic and visual associations.

This study found that overexpressing Dsg3 in the suprabasal epidermis of transgenic mice resulted in flaking skin and abnormal hair growth, supporting Dsg3's role in regulating epidermal differentiation.

This study found that cepharanthine significantly inhibits EqHV-8 infection in vitro and improves lung tissue pathology in infected mice by reducing oxidative stress through specific signaling pathways, suggesting its potential as a treatment for equid herpesvirus type 8.

This study found that while DP concentrations in dust were higher in male dormitories, DP in hair was higher in females, suggesting differing metabolism between genders and that hair DP mainly originates internally.

This case report presents a rare instance of recurrent ACTH-independent Cushing’s syndrome due to PBMAH, coinciding with the development of a pheochromocytoma, highlighting the need for thorough reevaluation in similar recurring cases.

This paper reviews the evolution of skin appendages and keratin-associated proteins among amniotes, proposing a model for their genetic divergence without new experimental results.
