BACKGROUND Hair is a unique character of mammals and has several functions, from protection of the skin to sexual and social communication. [] Key MethodRESULTS In this review, we summarized the principal anatomical and physiological aspects of the different types of human hair, and we considered the clinical significance of the different structures and the distribution of the hair in the human body. CONCLUSION This review could be the basis for improvement and progression in the field of hair research.
Anatomy and Physiology of Hair
Distinctive anatomy and physiology of hair follicle are presented in this chapter and can contribute to understand and heal different hair disorders.
Introductory Chapter: Hair Loss Introductory Chapter: Hair Loss
Hair loss can cause psychological problems for women rather than for men, because healthy hair is an essential factor for physical well‐being and females can show their charm, beauty and personal power with healthy hair.

Towards a body hair atlas of women of caucasian ethnicity
A preliminary study was conducted in 17 female volunteers to gain deeper insights into the characteristics of terminal Caucasian female body hair of different body parts and to identify relevant differences between body areas to improve body hair removal approaches.
The management of hirsutism
The normal physiology of hair growth, how to define excessive hair growth in a woman, and when it is essential to refer a patient for urgent secondary care advice and further management are covered.
A systematic review on the lipid composition of human hair.
The aim of this systematic review is to provide an overview of the lipid composition and ethnic differences of human hair, effects of external damage on lipid content and properties, and changes in hair lipid composition associated with disease states.
Therapeutics of premature hair graying: A long journey ahead
The aim of this paper was to review the manifestation and probable future interventions in preventing premature hair graying, and potential solutions toward this quandary are diet, herbal remedies, and temporary hair colorants.
Chemical and physical treatments damage Caucasian and Afro‐ethnic hair fibre: analytical and image assays
Sensory and structural characteristics of hair can be modified by chemical and physical treatments, as dyeing, brushing, but also by external factors, as sunlight radiation. However, quantitative
Light Microscopic Morphology of Indigenous Ghanaian African Hair from Scalp, Eyebrow, Axilla, and Pubic Regions
Bily regional differences in diameter of hair shaft and medullary presence were affirmed and continuous type medulla was predominant in all hairs, with a trend of percentage occurrence in descending order from the pubic, axilla, eyebrow, and scalp in both sexes.

A brief review of the salient elements of hair structure, chemistry, and the fundamental interplay that contributes to the properties of the hair fiber and its response to treatments are provided.
Methods in hair research: how to objectively distinguish between anagen and catagen in human hair follicle organ culture
Methods in hair research: how to objectively distinguish between anagen and catagen in human hair follicle organ culture is described.
Variations of scalp, pubic and axillary hair.
It is envisaged that variability in histomorphological and quantitative traits in different areas of human could be one of the important criteria for personal identification in forensic research.
Hair in the middle phalanges: clinical significance
The goal of this manuscript was to examine the clinical significance of this anthropological phenomenon in patients with unknown ancestry by performing a more in‐depth literature‐based evaluation of the trait.
Human hair cuticle : Biologically conspired to the owner's advantage
The structure, chemistry, and physical properties of the human hair cuticle are reviewed, and the role of the covalently linked fatty acids, notably 18-methyl eicosanoic acid (18-MEA), contained
[Loose anagen hair syndrome].
A typical case of loose anagen hair syndrome in a 4-year old girl is reported here. The key signs of this disease are the absence of hair cut since infancy, an easy and painless uprooting of the

Atomic force microscopy (AFM) has emerged as an ideal method for the non‐invasive examination of hair surfaces and is effective in characterization of the morphological structure and physical properties of human hair.
The distribution of hair on the phalanges of a sample population of Nigerian Yorubas in relation to sex, age and job type.
Age was not a factor in the distribution but individual's job type and sex had effect on hair distribution, hence people engaged in wet work should wear gloves.
Morphometry of human terminal and vellus hair follicles
The data suggest that hair follicle types in defined body regions represent rather homogenous groups and that particle‐based drug delivery may be a feasible approach, also in larger numbers of individuals.
