research 576 A preliminary study of melanogenic markers in the differentiation of the human hair follicle melanin unit
The study found markers indicating that cells responsible for hair color are differentiating in specific areas of the hair follicle.
research Changes in Different Melanocyte Populations During Hair Follicle Involution (Catagen)
Different melanocyte types in hair follicles either survive or die during the catagen phase.
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 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 The distribution of melanocytes and the degradation of melanosomes in fetal hair follicles
Fetal hair follicles have melanocytes with melanosomes at different stages, which are broken down into pigment particles in keratinocytes.
research Hair melanocytes as neuro-endocrine sensors—Pigments for our imagination
Hair melanocytes help the skin respond to stress and regulate hair pigmentation.
research Dermal papilla regulation of hair growth and pigmentation
Dermal papilla cells are key for hair growth and color, influencing hair type and size, and their interaction with stem cells could help treat hair loss and color disorders.
research A neuroendocrinological perspective on human hair follicle pigmentation
Brain hormones significantly affect hair color and could potentially be used to prevent or reverse grey hair.
research Nonpigmented hair removal using photodynamic therapy in animal model
Photodynamic therapy can remove nonpigmented hair in mice and might work for humans.
research A case of localized follicular hamartoma: an ultrastructural and immunohistochemical study
The hamartoma is an abnormal hair growth with limited development in the upper hair follicle.
research Preservation of melanoblasts of white hair follicles of segmental vitiligo lesions: A preliminary study
White hair follicles in vitiligo have fewer and less functional melanocytes.
research Panfolliculoma: report of two cases
Panfolliculoma is a rare, non-cancerous growth related to hair follicles.
research A pig model exploring the postnatal hair follicle cycle
Pigs are a good model for studying human hair growth and disorders.
research Pseudofolliculitis barbae; current treatment options
Stopping shaving or removing hair follicles usually resolves Pseudofolliculitis barbae.
research Pseudopili Annulati in a Dark‐Haired Individual: A Light and Electron Microscopic Study
A dark-haired Chinese girl had hair that looked banded under certain light but was normal under a microscope.
research Hypopigmentation in frontal fibrosing alopecia
FFA patients have fewer melanocytes and thinner skin compared to others.
research Characterization of the proteins of guinea-pig hair and hair-follicle tissue
Guinea-pig hair and follicle proteins are mostly similar, but follicles have more group 2 proteins and fewer group 3 and 4 proteins.
research Hair repigmentation in microcystic adnexal carcinoma
Hair repigmentation can indicate malignancy and should be investigated.
research Hypopigmented facial lesions: a case of eruptive tumor of follicular infundibulum
Consider TFI in facial hypopigmentation diagnoses and confirm with a biopsy.
research A case of widespread non-pigmented hair regrowth in diffuse alopecia areata
A woman with severe hair loss regrew mostly white hair after treatment.
research Weathering of the hairless scalp: a study using skin capacitance imaging and ultraviolet light-enhanced visualization
The study found that long-term sun exposure does not significantly affect follicular plugs on the scalp, and the scalp's appearance is unique compared to other body parts.
research Survival of patchwork melanoblasts is dependent upon their number in the hair follicle at the end of embryogenesis
More melanoblasts in hair follicles mean better survival and proper hair pigmentation.
research Rekindling the lost hair‐forming world
Non-hairy skin cells might be used to regenerate hair, helping with baldness and skin wounds.
research Human Hair Pigment: A Mild Isolation Procedure and a Method for Characterization
A new method was developed to gently isolate hair pigment while keeping its structure intact.
research Pigmented Hair-Thickening Fibers: A Camouflage Technique for Alopecia in Patients with Epidermolysis Bullosa
Colored hair-thickening fibers can help hide hair loss in some people with Epidermolysis Bullosa but may cause scalp irritation.
research Pigmentation of regenerated hairs after wounding
Regenerated hairs can regain their color if the wound occurs during a certain stage of hair growth, and this process is helped by specific skin cells and proteins.
research AN ULTRASTRUCTURAL POSTNATAL DEVELOPMENTAL STUDY OF THE INTEGUMENT OF THE PIG (SUS SCROFA)
Pig skin is similar to human skin, with no major changes as they age.
research Two case studies of persistent white hair regrowth after alopecia areata turning pigmented following treatment
White hair from alopecia areata can turn pigmented after treatment.
research Adiponectin negatively regulates pigmentation, Wnt/β-catenin and HGF/c-Met signalling within human scalp hair follicles ex vivo
Adiponectin reduces hair pigmentation and affects hair growth signals.
