hairless patches usually located in the vertex region. The patches appear atrophic without any signs of acute inflammation. The follicle orifices are missing (Figure 4). The clinical picture is applicable for numerous alopecias of different etiologies in their end stages.[13,14]Pseudopelade remains...

Scarring alopecias (Table 1) cause permanent hair loss and have in common the destruction of the hair follicles. Lesions show the loss of follicle orifices. So far, a broadly accepted classification system of scarring alopecias does not exist. The list of scarring alopecias is vast because ...
(which is expressed in both Henle’s and Huxley’s layers of the inner root sheath of the hair follicle) had been identified in six consanguineous Pakistani families [20]. Patients have sparse, coarse, dry, and tightly curled hair, usually blond or lighter than other family members [21,22...
The dermal papilla (DP) is a specialised mesenchymal component of the hair follicle (HF) that plays key roles in HF morphogenesis and regeneration. Current technical difficulties in preparing trichogenic human DP cells could be overcome by the use of highly proliferative and plastic human induced ...
We find that, in aged mice, epithelial cells escape from the hair follicle (HF) SC compartment to the dermis, contributing to HF miniaturization. Single-cell RNA-seq and assay for transposase-accessible chromatin using sequencing (ATAC-seq) reveal reduced expression of cell adhesion and ...
Obesity is a worldwide epidemic that predisposes individuals to many age-associated diseases, but its exact effects on organ dysfunction are largely unknown1. Hair follicles—mini-epithelial organs that grow hair—are miniaturized by ageing to cause hair loss through the depletion of hair follicle st...
External factors may result in hair loss, increased hair growth, or changes in the color and texture of the hair. External factors responsible for hair loss are drugs, radiation, traction, fungi, pesticides, plant toxins, heavy metals and several other chemicals. ...
The sebaceous gland secretes a mixture of fats (triglycerides, wax esters, squalene, and cholesterol) and cellular debris, which is discharged as sebum through the sebaceous duct connecting the gland to the hair follicle. Sebum helps to form the slightly greasy surface film of the skin; it thus...
