research Field melanin mapping of the hairless scalp
The study found a specific pattern of uneven melanin distribution on balding scalps that could help understand skin diseases caused by light exposure.
research Melanin Light Absorption as the Necessary but Not Sufficient Condition for Photoepilation: Miniaturization and Eclipse Phenomena
Melanin absorbing light is necessary but not enough for effective hair removal by light treatment.
research Scalp Hair Hypopigmentation in a Five-month-old Infant: A Quiz
research Amelanocytic Anhidrotic Alopecia Areata-like Phenotype After Allogeneic Hematopoietic Cell Transplant
The immune system can cause permanent skin and hair whitening by attacking pigment cells.
research Oral zinc sulphate causes murine hair hypopigmentation and is a potent inhibitor of eumelanogenesisin vivo
Oral zinc sulphate reduces dark hair color in mice.
research Enhanced Differentiation Potential of Pigmented Human Epidermal Equivalents
PmtHEE is a better model for studying pigmented skin because it includes melanocytes and shows improved cell differentiation.
research 13B “Temporary” Scalp Micropigmentation (Trichopigmentation)
Temporary scalp trichopigmentation creates a shaved hair look on the scalp using pigments that fade over time.
research Predicting hair cortisol levels with hair pigmentation genes: a possible hair pigmentation bias
Darker hair may lead to higher cortisol readings, suggesting a need to adjust for hair color in studies.
research Therapeutics of premature hair graying: A long journey ahead
Effective treatments for premature hair graying still require significant research.
research Isolated patchy heterochromia with pili annulati features on light and electron microscopy
Isolated patchy heterochromia with pili annulati can occur without other health issues.
research Melanogenesis Is Coupled to Murine Anagen: Toward New Concepts for the Role of Melanocytes and the Regulation of Melanogenesis in Hair Growth.
Hair color production is closely linked to the active growth phase of hair in mice and may also influence hair growth itself.
research Subclinical speckled perifollicular melanosis of the scalp.
The scalp has a natural speckled pattern of increased pigment around hair follicles, possibly linked to local hormone production.
research Hair
Hair analysis can detect drug use but is costly and interpretation is complex.
research Laser hair removal
Laser hair removal has advanced to effectively reduce hair for various skin types and hair colors.
research Hairless-knockout piglets generated using the clustered regularly interspaced short palindromic repeat/CRISPR-associated-9 exhibit abnormalities in the skin and thymus
Pigs without the Hairless gene showed skin and thymus changes, useful for studying human hair disorders.
research Rapid hair depigmentation in patient treated with pazopanib
Pazopanib treatment caused rapid hair color loss, possibly indicating its effectiveness.
research PREMATURE HAIR GRAYING: FACTORS THAT CONTRIBUTE THE MECHANISMS OF THE PROCESS
Premature hair graying is caused by various factors and mechanisms.
research Nevus comedonicus with lesional growth of terminal hair: An unusual case
Nevus comedonicus can sometimes grow terminal hair, challenging previous beliefs.
research Temporary hair removal by low fluence photoepilation: Histological study on biopsies and cultured human hair follicles
Low fluence photoepilation temporarily removes hair by targeting the hair follicle's pigmented area without severe damage.
research Focal Scalp Hair Heterochromia in an Infant
An infant had two different natural hair colors on the scalp with no health issues.
research Hair: A Review of Prominent Scalp Hair Changes throughout a Females’ Life
Women's hair gets thinner and grayer as they age, with treatments available for hair loss and graying.
research Single-cell transcriptomics reveals lineage trajectory of human scalp hair follicle and informs mechanisms of hair graying
The study found new details about human hair growth and suggests that preventing a specific biological pathway could potentially treat hair graying.
research Pigtail hair in acute telogen effluvium – Lest we forget!
Pigtail hair is a sign of new hair growth and should be recognized in hair loss conditions like acute telogen effluvium.
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 ABSENCE OF H2O2 BREAKDOWN IN HUMAN HAIR MEDULLA IMPLICATIONS IN FOLLICULAR MELANOGENESIS
Human hair medulla doesn't break down hydrogen peroxide, which may affect hair color formation.
research 518 Nutrient and stress sensing as novel physiological regulator of human hair pigmentation and greying: Role of mTORC1 activity
Blocking mTORC1 activity could increase hair pigmentation and potentially reverse greying.
research 15. Hair and Nails
Women with androgenetic alopecia have fewer terminal hairs, phenol in nail surgery is safe, and a new hair transplant method is faster and less damaging.
research Assessment of the photoprotection properties of hair cosmetics using the hemispherical directional reflectance method
Hair sunscreens were less effective than expected, especially for dark hair.
research Location and fine structure of melanocytes in human fetal scalp hair follicles.
