Hair loss is related to follicular density, programmed regrowth and hair productivity. 

Hair and Scalp Variation Related to Gender

Nowadays, there is an increasing interest for studying the gender differences of various human organ, particularly the skin and its appendices.

Following historical “tracks” of hair follicle miniaturisation in patterned hair loss: Are elastin bodies the forgotten aetiology?

It is proposed that alterations in elastin architecture may contribute to the failure of vellus‐like hair reverting back to their terminal status and may indicate a new area for therapeutic intervention.

What Can Complex Dietary Supplements Do for Hair Loss and How Can It Be Validly Measured—A Review

The TrichoScale® is a validated and non-invasive tool for quantifying hair loss/hair growth and is an ideal measuring instrument to objectively quantify the effectiveness of a hair loss treatment.

Short- and long-term exposure to trace metal(loid)s from the production of ferromanganese alloys by personal sampling and biomarkers

The environmental exposure to trace metal(loid)s (As, Cd, Cu, Fe, Mn, Pb, and Zn) was assessed near a ferromanganese alloy plant using filters from personal particulate matter (PM) samplers

The Life Cycle of the Hair Follicle



Hair through the female life cycle

In evaluating the patient complaining of hair loss, the clinician needs to be aware of how age affects hair growth and the emerging evidence implicating environmental factors is of particular interest as, unlike genes, such factors may be amenable to intervention.

Follicular miniaturization in female pattern hair loss: clinicopathological correlations

A low terminal/vellus ratio could be due to a preferential increase in the number of terminal follicles in kenogen rather than to a true increase inThe number of vellus follicles.

Hair and scalp disorders

This chapter outlines of some of the more common conditions affecting the hair and scalp in children, including scarring and non-scarring disorders, and the approach to the child with excessive hair growth.

Transplants from balding and hairy androgenetic alopecia scalp regrow hair comparably well on immunodeficient mice.

It is shown that miniaturized hair follicles of pattern alopecia can quickly regenerate once removed from the human scalp and can grow as well as or better than terminal follicles from the same individual.

This paper is to propose a method that is applicable to humans and that is able to discriminate the two components of the resting hair population i.e. the telogen and the exogen hair follicles.

Thickness, medullation and growth rate of female scalp hair are subject to significant variation according to pigmentation and scalp location during ageing.

The data shows that the reduced growth rate of terminal hairs is in fact limited to the pigmented hairs, and the potential role of drug induced modifications of hair pigmentation should be taken into account during the interpretation of efficacy.

Characteristic features of Japanese women's hair with aging and with progressing hair loss.

Female patients complaining about hair loss: documentation of defective scalp hair dynamics with contrast-enhanced phototrichogram.

In all sites slower growth rates and decreased anagen percentages indicate a defective hair replacement programme distinguishing L patterns from diffuse hair loss and from apparently unaffected patients complaining of chronic hair loss.

Phototrichogram analysis of Japanese female subjects with chronic diffuse hair loss.

Hair growth patterns of 101 Japanese female subjects with diffuse, chronic hair loss and 58 healthy Japanese female volunteers were categorized into subgroups using noninvasive quantitative methods
