A 73-year-old man's grey-white hair turned dark brown after eczema treatment.
research Heptaminol-Induced Hair Depigmentation in a Hemodialysis Patient
Stopping heptaminol medication reversed hair color loss in a patient on dialysis.
research Cutaneous hydroxystereoid dehydrogenases and rat-hair-cycle
Certain enzymes react strongly with some hormones in rat skin during hair growth, mainly in sebaceous glands and hair sheaths.
research Effects of Gonadal Steroids on Melanocytes in Developing Hamsters
Androgens increase pigmentation in young hamsters, but estrogens can reverse this effect.
research Hair follicle changes following intense pulsed light axillary hair reduction: histometrical, histological and immunohistochemical evaluation
Intense pulsed light treatment effectively reduces underarm hair by making hair follicles smaller and extending their resting phase.
research Human Hair Keratins.
research 8 Hair follicles and associated glands as androgen targets
Androgens like testosterone affect hair growth and oil production differently across body parts and individuals.
research Graying of Hair Produced by Ingestion of Phenylthiocarbamide

research In Vitro hair growth and hair tanning activities of mangosteen pericarp extract on hair dermal papilla cells
Mangosteen extract may help with hair growth and prevent graying.
research Polyclonal origin and hair induction ability of dermal papillae in neonatal and adult mouse back skin
Dermal papillae cells, important for hair growth, come from multiple cell lines and can be formed by skin cells, regardless of their origin or hair cycle phase. These cells rarely divide, but their ability to shape tissue may contribute to their efficiency in inducing hair growth.
research Electron paramagnetic resonance (EPR) spectroscopy for investigating murine telogen skin after spontaneous or depilation-induced hair growth
EPR spectroscopy showed that spontaneous hair growth results in thicker skin and less pigmented hair than depilation-induced growth.
research Hypopigmented facial lesions: a case of eruptive tumor of follicular infundibulum
Consider TFI in facial hypopigmentation diagnoses and confirm with a biopsy.
research Desmodesmus pannonicus Water Extract Inhibits Melanin Synthesis and Promotes Wound Healing
Desmodesmus pannonicus water extract may help reduce skin pigmentation, heal wounds, and promote hair growth.
research A Comprehensive Review on Skin Pigmentation-Types, Causes, and Treatment
Skin pigmentation varies due to genetics, UV exposure, and medications, with treatments available but requiring medical advice.
research Pohl-Pinkus constrictions of hair following chemotherapy for Hodgkin's disease
Chemotherapy caused the patient's hair to have alternating thick and thin segments.
research Teatro D. Fernando: um teatro de curto prazo
Crataegus pinnatifida extract promotes hair growth in mice.
research Exploring the potential effect and mechanisms of protocatechuic acid on human hair follicle melanocytes

research Cell Differentiation in Human Anagen Hair and Hair Follicles Studied with Anti-Hair Keratin Monoclonal Antibodies
research Thyroid Hormones Directly Alter Human Hair Follicle Functions: Anagen Prolongation and Stimulation of Both Hair Matrix Keratinocyte Proliferation and Hair Pigmentation
Thyroid hormones help hair grow, reduce hair loss, and increase hair pigment.
research Is There a Rationale for the Use of an Alpha-Melanocyte-Stimulating Hormone Analog to Improve Gray Hair Repigmentation?
PT-20 did not significantly improve gray hair repigmentation.
research Facial hyperpigmentation caused by pigmented demodicosis
Facial hyperpigmentation improved with oral isotretinoin and ivermectin cream after Demodex mites were identified as the cause.
research De Novo Production of Dermal Papilla Cells during the Anagen Phase of the Hair Cycle
New cells are added to the hair's dermal papilla during the active growth phase.
research Vibrissa hair bulge houses two populations of skin epithelial stem cells distinct by their keratin profile
There are two types of stem cells in rodent hair follicles, each with different keratin proteins.
