Prednisone reduces organ mast cell infiltration but does not alter the abnormal appearance of mast cells in systemic mastocytosis.

Melanocytes are destroyed by factors needed for melanin production, causing vitiligo and gray hair.

Hair stops producing melanin as it transitions from the growth phase to the resting phase.

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.

Poliosis circumscripta is a patch of white hair caused by lack of melanin, linked to genetic and acquired conditions.

Tiger tail bands in hair are caused by wavy hair fibers with melanin, unlike straight fibers in normal hair.

Melanin in black hair protects it from sun damage better than light-brown hair.

Hair dye colors mainly target melanin granules in black hair.

ATP increases melanin production in skin after UV exposure, with the P2X7 receptor being crucial for this process.

Human skin and hair color variation is mainly due to melanin produced by a few genes, with melanin protecting against sun damage.

Hair acts as a significant natural sun barrier, with protection increasing based on hair density, thickness, and melanin presence.

Clotrimazole, an antifungal cream, may safely reduce skin pigmentation by breaking down the enzyme needed for making melanin.

Stressed fibroblasts greatly increase melanin production in hair, skin, and eye cells, mainly due to a growth factor called bFGF.

Palmitoyl tetrapeptide-20 may help reduce hair greying and increase melanin production.

Finasteride reduces melanin production, possibly treating hyperpigmentation and melanoma, but needs more safety research.

Melanin density affects hair color, and this method can help in cosmetic assessments and diagnosing hair diseases.

Rice bran extract boosts melanin production in hair follicles.

Cirsium japonicum flower extract increases melanin production and could help treat depigmentation conditions.

Melanin may help melanoma cells grow by aiding their metabolism.

Protocatechuic acid can reduce melanin production and boost antioxidant activity in hair follicles.

3D imaging of skin biopsies offers better accuracy but is time-consuming and can't clear melanin.

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.

CD34+ hair follicle stem cells can become melanin-producing cells for treating skin conditions.

Poliosis causes white hair patches due to lack of melanin.

Reflectance spectroscopy can noninvasively track hair growth stages by measuring skin reflectance and melanin changes.

Hair color is determined by melanin and can be affected by genetic conditions like albinism.

PCE-DP brightens skin and promotes hair growth by enhancing cell growth and reducing melanin uptake.

Safflower extract increases melanin production in certain skin cells without harming them.

Hair with more melanin resists weather damage better.

Tribuloside can increase skin pigmentation by enhancing melanin production and distribution.
