Silencing certain circadian clock genes increases skin pigmentation.
research The Antimycotic Agent Clotrimazole Inhibits Melanogenesis by Accelerating ERK and PI3K/Akt-Mediated Tyrosinase Degradation
Clotrimazole, an antifungal cream, may safely reduce skin pigmentation by breaking down the enzyme needed for making melanin.
research Finasteride Inhibits Melanogenesis Through Regulation of the Adenylate Cyclase in Melanocytes and Melanoma Cells
Finasteride reduces melanin production, possibly treating hyperpigmentation and melanoma, but needs more safety research.

Rice bran extract boosts melanin production in hair follicles.
research Beyond the Epidermal-Melanin-Unit: The Human Scalp Anagen Hair Bulb Is Home to Multiple Melanocyte Subpopulations of Variable Melanogenic Capacity
The human scalp hair bulb contains different types of melanocytes with varying abilities to produce melanin.
research Hair Growth Cycle Affects Hair Follicle Destruction by Ruby Laser Pulses
Ruby laser pulses best destroy hair follicles during the growth phase and effectiveness varies with laser intensity; melanin is key for targeting, and timing treatments can improve results.
research Female Pattern Hair Loss: Clinical and Laboratory Findings and Trichoscopy Depending on Disease Severity

research Interaction Between Stem Cell Factor and Endothelin-1: Effects on Melanogenesis in Human Skin Xenografts
SCF and ET-1 together significantly increase skin pigmentation and melanin production.
research Critical Role of ATP-P2X7 Axis in UV-Induced Melanogenesis
ATP increases melanin production in skin after UV exposure, with the P2X7 receptor being crucial for this process.
research HGF/SF Increases Number of Skin Melanocytes but Does Not Alter Quality or Quantity of Follicular Melanogenesis
HGF/SF increases skin melanocytes but doesn't change melanin type or amount.
research Dopa Oxidase Activity in Hair, Skin, and Ocular Melanocytes Is Increased in the Presence of Stressed Fibroblasts
Stressed fibroblasts greatly increase melanin production in hair, skin, and eye cells, mainly due to a growth factor called bFGF.
research 3,4,5-Tri-O-Caffeoylquinic Acid Promoted Hair Pigmentation Through β-Catenin and Its Target Genes
A substance called TCQA could potentially darken hair by activating certain genes and increasing melanin.
research A Comparative Study of Skin Transcriptomes and Histological Observations for Black and White Hair Colors of Giant Panda
The study found that giant pandas have more melanin in black hair follicles than white, with gene expression differences that could affect hair color and skin health.
research Hydrophilic Melanin as a Potential Hair Growth Stimulant: A Secondary Observational Study
Hydrophilic melanin may help hair grow by improving blood flow and regeneration.
research Role of Dermal Factors Involved in Regulating the Melanin and Melanogenesis of Mammalian Melanocytes in Normal and Abnormal Skin
Dermal factors are crucial in regulating melanin production in skin.
research Inhibitory Activities of Some Traditional Chinese Herbs Against Testosterone 5α-Reductase and Effects of Cacumen Platycladi on Hair Regrowth in Testosterone-Treated Mice
