Hair has many useful biologic functions, including protection from the elements and dispersion of sweat-gland products (e.g., pheromones). It also has psychosocial importance in our society, and patients with hair loss (alopecia) (Table 1) or excessive hair growth often suffer tremendously. Not surprisingly, the demand for drugs that alter hair growth and appearance has led to a multibillion-dollar industry, yet few drugs that are effective for these purposes are available. However, recent… Expand

Biology of human hair: know your hair to control it.
TLDR
General aspects of hair biology are reviewed, as well as the most recent contributions to understanding hair pigmentation and the regulation of hair development, indicating methods for genetic/biochemical modulation of HF components for the treatment of hair diseases. Expand
EEMCO Guidance for the Assessment of Hair Shedding and Alopecia
TLDR
Clinical evaluations benefit from a few additional specific techniques that enhance the perception of hair (re-) growth, shedding and alopecia, especially when the hair loss is accompanied by scarring. Expand
The genetically programmed hair growth cycle and alopecia: what is there to know?
TLDR
The last 20 years have seen a vast change in research activity into the regulation of hair growth in health and disease and, over the next 5 years, this should include further important glimpses of the nature of the hair follicle's clock machinery. Expand
Herbal preparations for the treatment of hair loss
TLDR
The plants with the most evidence-based effect against alopecia are Curcuma aeruginosa (pink and blue ginger), Serenoa repens (palmetto), Cucurbita pepo (pumpkin), Trifolium pratense (red clover), and Panax ginseng (Chinese red ginsenge). Expand
Exploring the potential of herbal drugs for the treatment of hair loss
TLDR
In present article, information about loss of hair loss, types of alopecia, causes and various medicinal plants and parts they’re of used in treatment prophylaxis or treatment ofhair loss are covered. Expand
Drug that Causes Hair Loss and Promotes Hair Growth-A Review
TLDR
The difficult task in diagnosing hair and hair disorders is to distinguish between a true disorder and a subjective complaint and to analyze the underlying pathogenesis. Expand
The Biology of Hair Growth
TLDR
The functions of hair, its structure and the processes occurring during the hair growth cycle, the changes which can occur with the seasons, and the importance of the main regulator of human hair growth, the androgens are reviewed. Expand

Clinical updates in hair.
TLDR
Research findings indicate that levels of androgen-metabolizing enzymes and receptors differ in the scalps of women versus men, which may be important in formulating more effective hair growth treatments in the future. Expand
Towards a molecular understanding of hair loss and its treatment.
TLDR
The characteristics of common hair loss diseases are outlined, and ways in which recent advances in hair follicle biology could be translated into effective therapies for these conditions are discussed. Expand
ANDROGEN METABOLISM AS IT AFFECTS HAIR GROWTH IN ANDROGENETIC ALOPECIA
TLDR
In vitro studies of scalp skin and hair follicles have begun to define specific alterations in androgen metabolism at the local level that may play a key role in pathogenesis, and the prominent role of 5-reductase in these studies suggests that inhibitors of this enzyme may provide new therapeutic opportunities for patients with androgenetic alopecia. Expand
Growth factors and cytokines in hair follicle development and cycling: recent insights from animal models and the potentials for clinical therapy.
TLDR
These animal models have confirmed the importance of growth factors and cytokines in hair follicle development and cycling, and have formed the foundation for potential clinical therapy of hair growth disorders, particularly alopecia. Expand
Hair follicle growth controls.
TLDR
Research in hair biology has embarked in the pursuit for molecules that control hair growth, and knowing how these molecules work gives the tools for understanding and treating patients with hair disorders. Expand
The feasibility of targeted selective gene therapy of the hair follicle
TLDR
The selective targeting of the lacZ reporter gene to the hair follicles in mice after topical application of the gene entrapped in liposomes demonstrates that highly selective, safe gene therapy for the hair process is feasible. Expand
Towards defining the pathogenesis of the hairless phenotype.
TLDR
Hairless mice offer a unique model for dissecting the as yet obscure functional properties of the hr gene product in maintaining follicle integrity during normal catagen, and it is proposed that dermal cysts in hr skin arise from (i) the central ORS, (ii) bulge-derived cells, or (iii) the disintegrating proximal ORS under the influence of dermal papilla remnants.

TLDR
Kinetic constants have been evaluated for several enzymes which mediate dihydrotestosterone formation, including 5a-reductase, and the cytochrome P-450 aromatase enzyme in isolated human hair follicles and sebaceous glands from scalp of men and women with androgenetic alopecia, indicating that similar steroid mechanisms may be taking place in men andWomen, but the amount or level of enzymes vary.

Neural mechanisms of hair growth control.
TLDR
It is suggested that the study of piloneural interactions promises important insights into general principles of neuroepithelial communication, namely during epithelial morphogenesis and remodeling, as well as targeted manipulations for managing hair growth disorders. Expand
