research Micropigmentation and microblading
Scalp micropigmentation is a safe way to hide hair loss and scalp scars by tattooing tiny dots that look like hair follicles.
research Skin Problems of Blacks
Black patients have unique skin conditions that require specific knowledge for proper treatment.
research Scalp Micropigmentation: A Clinicopathologic Correlation
Trichoscopy effectively visualizes scalp micropigmentation without invasive methods.
research PREMATURE HAIR GRAYING: FACTORS THAT CONTRIBUTE THE MECHANISMS OF THE PROCESS
Premature hair graying is caused by various factors and mechanisms.
research BIOCHEMICAL AND HISTOCHEMICAL STUDIES ON WHITE, BROWN AND BLACK SKIN REGIONS OF THE GUINEA PIG
Brown skin in guinea pigs has more ascorbic acid and related enzymes, black skin uses ascorbic acid well, and white skin has the most protein.
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 Change in Hair Color in Mice Induced by Injection of α-MSH
Injecting α-MSH made mice's hair turn black.
research Early skin seeding regulatory T cells modulate PPARγ-dependent skin pigmentation
Early regulatory T cells are crucial for normal skin pigmentation.
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 Reversible Hyperpigmentation: A Diagnostic Dilemma
Vitamin B12 deficiency can cause reversible skin darkening.
research Tyrosinase Depletion Prevents the Maturation of Melanosomes in the Mouse Hair Follicle
Reducing Tyrosinase prevents mature color pigment cells from forming in mouse hair.

Pueraria thunbergiana extract may help prevent hair from turning gray.
research Melanocyte Subpopulation Turnover During the Human Hair Cycle: An Immunohistochemical Study
Melanocyte activity in hair follicles is linked to the hair growth cycle, being active in growth phases and inactive in rest phases.
research Skin Hyperpigmentation in Complex Regional Pain Syndrome (CRPS) (P3.315)
Skin pigmentation increases in CRPS-affected areas and improves with symptom relief.
research Dyeing regions of oxidative hair dyes in human hair investigated by nanoscale secondary ion mass spectrometry
Hair dye colors mainly target melanin granules in black hair.
research Influence of prostaglandin F2α and its analogues on hair regrowth and follicular melanogenesis in a murine model
Prostaglandin F2alpha and related compounds can increase hair growth and darken hair in mice.
research Reversible Facial Hyperpigmentation Associated With Vitamin B12 Deficiency
Vitamin B12 deficiency can cause facial dark spots that go away with treatment.
research PPAR‐γ signalling as a key mediator of human hair follicle physiology and pathology
PPAR-γ is important for healthy hair and its problems, and more research on PPAR-γ treatments is needed.
research Unusual dermoscopic features in a patient with alopecia areata
