research Fibrosing Alopecia in a Pattern Distribution
Some people with pattern hair loss may also have scalp inflammation and scarring similar to lichen planopilaris.
research A histologic review of 27 patients with lichen planopilaris
The conclusion is that certain scalp tissue changes are characteristic of lichen planopilaris, with mucinous perifollicular fibroplasia being a new feature for diagnosis.
research Localized cutaneous necrosis associated with the antiphospholipid syndrome
A woman with lupus experienced skin death due to a blood clotting disorder after stopping a blood thinner, which healed with treatment.
research Penetration and Distribution in Human Skin Focusing on the Hair Follicle
Targeting drugs to hair follicles can treat skin conditions, but reaching deep follicle areas is hard and needs more research.
research Hair follicle immune privilege in autoimmune and immune-mediated alopecias: paths toward reestablishing immune tolerance
Different types of alopecia cause hair loss due to immune system issues, with some allowing regrowth and others causing permanent loss.
research Distinguishing histopathologic features of acantholytic dermatoses and the pattern of acantholytic hypergranulosis
Different skin diseases show unique patterns of skin cell separation, cell death, and granular layer changes.
research Author response: Hair follicle epidermal stem cells define a niche for tactile sensation
Skin stem cells in hair follicles are important for touch sensation.
research Hair follicle associated pluripotent (HAP) stem cells jump from transplanted whiskers to pelage follicles and stimulate hair growth
Stem cells from whiskers can be transplanted to stimulate hair growth.
research Inherited Disorders of the Hair
The study concluded that genetic mutations affect human hair diseases and identified key genes and pathways involved in hair growth and cycling.
research Author response: Coordinated hedgehog signaling induces new hair follicles in adult skin
Hedgehog signaling can create new hair follicles in adult skin but may increase cancer risk.
research Alopecia in Epidermolysis Bullosa
The document suggests that certain protein deficiencies and scalp blistering in Epidermolysis Bullosa may cause hair loss.
research Hair Loss in Autoimmune Cutaneous Bullous Disorders
Hair loss in autoimmune blistering skin diseases varies and may regrow with disease control.
research Histology of the Human Hair Follicle
Understanding hair follicle structure is key for treating hair disorders and could help develop new treatments.
research Fibrosing alopecia in a pattern distribution
Fibrosing alopecia in a pattern distribution is a unique hair loss condition that may respond to antiandrogen therapy.
research Permanent alopecia as a manifestation of chronic graft-versus-host disease of the scalp: clinical, dermoscopic and histopathological observations
Permanent hair loss after a stem cell transplant can be a sign of chronic immune system attack on the scalp.
research Deciphering the functions of the hair follicle infundibulum in skin physiology and disease
The hair follicle infundibulum plays a key role in skin health and disease, and understanding it better could lead to new skin disease treatments.
research Central centrifugal cicatricial alopecia
CCCA is a common, progressive hair loss condition that may not always be linked to hair care practices and requires a biopsy for diagnosis.
research 1310 Anti-aging effects of retinoid hydroxypinacolone retinoate on skin models
Hydroxypinacolone retinoate is a potent anti-aging ingredient for skin that is more effective and less irritating than other forms of retinoids.
research Nestin is a marker of unipotent embryonic and adult progenitors differentiating into an epithelial cell lineage of the hair follicles
Nestin identifies specific progenitor cells in hair follicles that can become outer root sheath cells.
research 1313 Fzd2 controls multiple aspects of epidermal development through distinct signaling mechanisms
Fzd2 is important for skin and hair development through various signaling ways.
research Staining of human skin with RGB trichrome unveils a proteoglycan-enriched zone in the hair dermal sheath
A new staining method shows a special area in the hair's skin layer with lots of proteoglycans.
research Nestin as a marker of unipotent epithelial progenitor cells differentiate into outer root sheath keratinocytes in embryonic and adult hair follicles
Nestin-expressing cells turn into a specific type of skin cell in hair follicles during development and in adults.
research Nestin as a marker of unipotent epithelial progenitor cell differentiation into outer root sheath keratinocytes in embryonic and adult hair follicles
Nestin marks cells that can become a specific type of skin cell in hair follicles of both developing and adult mice.
research Basal cells in the epidermis and epidermal differentiation
The exact identity of skin stem cells and how skin cells differentiate is not fully known.
research 1314 Advanced age impairs self-renewal and biases fate choice of hair follicle dermal stem cells
Older hair follicle stem cells have a reduced ability to renew themselves, leading to more hair loss.
research 1315 An Integrated model of alopecia areata biomarkers highlights both Th1/Th2 upregulation, with stronger correlations between Th2 activation and disease severity
Both Th1 and Th2 immune responses are increased in alopecia areata, with Th2 response more strongly linked to how severe the disease is.
