Introduction To evaluate scalp hair steroid concentrations as a monitoring tool for androgen control in adults with congenital adrenal hyperplasia due to 21-hydroxylase deficiency (CAH). Methods Scalp hair 17-hydroxyprogesterone (17-OHP), androstenedione, testosterone, cortisol, cortisone, progesterone, prednisolone and prednisone concentrations were measured by means of LC-MS/MS in women (N=27) and men (N=15) with CAH and controls (37 women, 42 men). Results In CAH men and women, 17-OHP levels in hair show...
Currently, hair straightening has become a regular hair treatment for women but likewise for men. Several studies have shown that thermal straightening has an influence on the concentration of ethyl glucuronide and of drugs of abuse content in hair. Heat treatment of hair may decrease concentrations of cocaine (COC) and of cocaethylene (CE) in hair and increase concentrations of benzoylecgonine (BZE). The goal of this study was to evaluate the influence of thermal straightening on anhydroecgonine methyl est...
Across the African Diaspora, hair is synonymous with identity. As such, Black women use a variety of hair products, which often contain more endocrine-disrupting chemicals than products used by women of other races. An emerging body of research is linking chemicals in hair products to breast cancer, but there is no validated instrument that measures constructs related to hair, identity, and breast health. The objective of this study was to develop and validate the Black Identity, Hair Product Use, and Breas...
Beard hair serves as an important additional donor supply to support hair transplantation in hirsute patients with extensive alopecia and lacking sufficient occipital hair. However, the efficacy and safety of large-scale beard hair extraction have not been studied extensively in the East Asian population.
Steroid hormone analysis is widely used in health- and stress-related research to get insights into various diseases and the adaption to stress. Hair analysis has been used as a tool for the long-term monitoring of these steroid hormones. In this study, a liquid chromatography-tandem mass spectrometry method was developed and validated for the simultaneous identification and quantification of seven steroid hormones (cortisone, cortisol, 11-deoxycortisol, androstenedione, 11-deoxycorticosterone, testosterone...
In order to explore the level of heavy metal pollution in human hair of residents in Huainan City and provide theoretical guidance for prevention and control of heavy metal pollution, human hair samples from 174 residents in Huainan City were collected so that heavy metal (Cr, Cu, Pb, Zn, As, and Fe) concentrations in scalp hair could be tested, and meanwhile their relationship with sex, age, and spatial distribution characteristics could be explored as well. According to the final analysis, the average con...
Human scalp hair is a valuable matrix for determining long-term cortisol concentrations, with wide-spread applicability in clinical care as well as research. However, pediatric reference intervals are lacking. The aim of this cross-sectional study is to establish age-adjusted reference intervals for hair cortisol in children and to gain insight into hair growth velocity in children up to 2 years old.
In the last century, human scalp hair morphology has been studied from multiple, and sometimes mutually exclusive, perspectives by anthropologists, biologists, geneticists, forensic scientists, and cosmetic scientists. Here, we review and synthesize historical and current research on hair to better understand the scientific basis and biological implications of hair microstructure and morphology. We revisit the origins of existing nomenclature regarding hair morphology and classifications, discuss the curren...
Allergic contact dermatitis is an inflammatory condition that less commonly presents with scalp involvement. Recently, T regulatory cells have been documented to be residents of hair follicles, illuminating why contact allergens are less likely to elicit dermatitis in the scalp.
When head hair is not suitable or not available, body hair, such as leg or beard hair might be the most suitable sample for drug hair analysis. Information about the time course of drugs in hair, from the different anatomical body sites, should still be well documented.
Given that unwanted hair growth (hirsutism, hypertrichosis) can cause major psychological distress, new pharmacological treatment strategies by safe and effective hair growth inhibitors that do not destroy the hair follicle (HF) and its stem cells need to be developed.
Patients with sarcoidosis often experience fatigue and psychological distress, but little is known about the etiology of these conditions. While serum and saliva steroid hormones are used to monitor acute steroid levels, scalp hair analysis is a relatively new method enabling measurement of long-term steroid levels, including hair cortisol reflecting chronic stress. We investigated whether scalp hair cortisol and testosterone levels differ between sarcoidosis patients both with and without fatigue and gener...
We read with great interest the literature review by Scheier et al on subgaleal haematoma due to hair pulling in Acta Paediatrica (1). The authors of this paper suggest their review showed that subgaleal hematoma can result from the mechanical stress placed on the scalp by hair braiding or the child pulling on their hair. We would like to share an important case from our hospital archives, which highlights the fact that not all cases of subgaleal haematoma secondary to hair pulling are benign and self-resol...
Different drugs can affect the hair. Among the various types of drug-induced hair changes, hair colour change is a rare phenomenon which is less reported in the literature. Hair colour changes include lightening of the hair, whitening or returning to the original colour and even change to a new colour. In this article we report a patient presenting with hair yellowing due to topical treatment with minoxidil and discuss the phenomenon of drug-induced hair colour changes.
In the process of daily grooming, human hair often undergoes heat treatments. These treatments create temperature gradients inside individual hair fibers or bundles of hair which can lead to hair damage.
Hair analysis for the assessment of cannabis active use from passive consumption may be failed when performed by the sole detection of compounds present in plant material as well as in cannabis smoke like Δ-9-tetrahydrocannabinol (THC), cannabidiol (CBD), and cannabinol (CBN). For this reason, the determination of 11-nor-9-carboxy-Δ-9-tetrahydrocannabinol (THC-COOH) has been proposed by the Society of Hair Testing (SoHT) in order to prove active cannabis consumption. The identification of THC-COOH in hair...
Chemotherapy-induced alopecia (CIA) affects the majority of patients receiving chemotherapy (CT) for early breast cancer. It is a highly distressing side effect of CT, with psychological and social impact. Primary aim of the present analysis was to assess the efficacy of scalp cooling with DigniCap® in preventing CIA. Success rate was defined as patients' self-reported hair loss
To determine the association of age, life-style habits and the self-perception of hair condition with the objectively measured physical properties of hair in Caucasian females with brown hair.
Randomized controlled trials (RCT) of scalp cooling (SC) to prevent chemotherapy induced alopecia (CIA) did not evaluate its effect on hair regrowth (HR) and was conducted in a predominantly taxane (T) treated population. We conducted an RCT of SC in a setting of anthracycline (A) and taxane chemotherapy (CT) and assessed its effect on CIA and HR.
Hair loss affects millions of people worldwide, but currently available treatment options are often dissatisfying due to side effects or limited efficacy. Pea sprout extract has been shown to improve hair density when applied topically, but its mode of action and effectiveness upon oral administration remain unknown. Our study has now shown that the application of a fluid containing 2% pea sprout extract on a defined scalp zone of 10 volunteers enhances the expression of defined genes relevant for hair, nam...
Measurement of hair drug content may be a reliable biomarker of the history of drug exposure, allowing to assess patient long-term compliance. Studies on correlations between antiepileptic drugs intake and their hair contents are limited. The aim of the study was to determine the association between the history of levetiracetam administration and its content in rat hair in controlled laboratory conditions. Additionally, the effects of levetiracetam on hair growth rate and body weights were examined. Three g...
In gender minority patients, electrolysis and laser hair removal may be necessary to reduce facial and body hair in individuals seeking a more feminine appearance and/or modified gender expression. These procedures may also be required preoperatively for some gender-affirming surgeries.
A study has been undertaken over a period of 8 years of tissue reactions in interventional radiology patients receiving cumulative air kerma values to their scalp above 3 Gy. Patients receiving doses to the scalp above this trigger level have been followed up to determine when such effects occur and provide reassurance if they do. The study has shown that hair thinning and hair loss are the more likely effects and may occur in 50% of patients at dose above 4.5 Gy.
The aim of this study was the monitoring of the levels of parabens (PBs) and triclosan (TCS) in head hair samples of women collected during the first months of their pregnancy. Personal details concerning somatometric and demographic characteristics, dietary habits, use of personal care products and the medical and obstetrical history of the pregnant women as well as infants' somatometric characteristics and health condition were recorded through relevant questionnaires. Ninety five hair samples were collec...
The human hair follicle is a neuroendocrine mini-organ that can be used to study aging processes in vitro. Neurotrophins maintain homeostasis in hair biology via the Trk-family of receptors. TrkA, the high affinity receptor for nerve growth factor (NGF), is expressed in hair follicle melanocytes and keratinocytes, where it regulates proliferation, differentiation and apoptosis and may thereby play a role in hair pigmentation and growth. We investigated TrkA expression during the human hair cycle and the eff...
