This study bibliometrically analyzed the attributes of intellectual research which is expressed through the signature of hair-related papers in the domestic academic journal. The study results revealed that a total of 824 papers were published from 1959 to 2013. In terms of research method trends, the analysis of effectiveness was most common. According to analysis of the words derived from the signature, 'hair' was most frequently searched for at 623 times, followed by 'effectiveness analysis (145 times),' 'dyeing (117 times),' 'hair loss (80 times),' 'permanent wave (69 times),' 'hair damage (67 times)' and 'scalp (58 times).' After investigating the usage of the words in the paper signature, similar words were grouped and classified by similarity depending on research topic. In this case, 'hair for hairdressing' was the highest with 873 cases, followed by 'hair (262 cases),' 'dyeing (223 cases)' and 'scalp (89 cases).' In terms of the social functions of hair, 'hair science' was the highest with 432 cases, followed by 'hair health (132 cases),' 'hair industry (130 cases)' and 'hair psychology (68 cases).' The development of a systematic word system in the hair industry could be a framework for future research activities. The analysis of research trends by year is aimed to determine into which sector these research activities have converged or are related to. In order for the beauty sector to be established as a field for study, it is necessary to establish an academic system through the selection of beauty-related terminologies in a logical manner in future studies. In addition, it is necessary to perform an integrated and converged study by examining the research methods between the beauty industry and other sectors.

Article 254 (4) of the Criminal Procedure Act provides that “The Facts constituting the crime shall be stated clearly by specifying the time & date, place, and method of crime”. In case the facts constituting the crime(count) is not be stated clearly, the public prosecution shall be dismissed by judgement. The legislative purport of ‘count specification’ is not only set limits to object of trials, but also protect the procedural rights of defendants. For that reason the time & date, place, and method of crime in the prosecution shall be stated clearly for defendants so as to exert their procedural rights without difficulty. In the ‘illegal drug use case’, however, not a few suspects deny their crimes. In such circumstances, prosecutors have no choice but to presume the date of crime just basing urine analysis or hair analysis. So, the facts constituting the crime have to be stated generally. The Supreme Court tended to take a generous stand on the issue of ‘count specification’ in illegal drug use cases before the 2000s. However, in 1999, the Supreme Court dismissed ‘illegal drug use case’ just based on hair analysis. [Supreme Court Decision 1998Do3293 Delivered on June 11, 1999 [Violation of the Act on the Control of Narcotics, etc. (Psychotropic)]. After that, the Supreme Court tends to judge illegal drug use cases on a case by case basis. Therefore, it is necessary to analyze the standpoint of the Supreme Court and suggest a manifest criterion on that issue. Issues of this paper are admissibility & reliability of hair analysis as an evidence, count specification & object of trials in the ‘illegal drug use case’ and related problems. This paper reviews leading precedents on the issues and suggests possible solutions to the problems.

Analysis of pubic hair as an alternative specimen to scalp hair: A contamination issue

Lee, S.,Han, E.,In, S.,Choi, H.,Chung, H.,Chung, K.H. Elsevier Sequoia 2011 Forensic Science International Vol. No.

Pubic hair is often analyzed as an alternative to scalp hair to prove previous drug use. However, urine is a potential source of external contamination. In the present study, the concentrations of methamphetamine (MA) and amphetamine (AP) in both scalp and pubic hair from illegal MA users were compared. Furthermore, in order to investigate the external contamination of pubic hair by urine, MA and AP absorbed into pubic hair that had been contaminated with authentic urine from a MA user were measured using a previously validated method. The effect of shampoo-wash on the contaminated pubic hair was also examined. However, no correlation was found in the MA and AP concentrations between scalp and pubic hair from illegal MA users. As the number of contamination events by authentic urine increased, the concentrations of MA and AP in pubic hair increased. Both MA and AP were detected in the first methanol washes of the contaminated hair samples but were not detected in the second methanol washes. As the number of shampoo-washes of the contaminated pubic hair increased, the concentrations of MA and AP gradually decreased. Even though pubic hair can be used as an alternative to scalp hair to prove previous drug use, it should be avoided when estimating drug use history. It should be also noted that higher quantitative results in pubic hair do not necessarily represent heavier drug use.

A quality control material (QCM) is a necessity in hair drug analysis, but it is not always easy to have an authentic hair sample containing various target drugs and metabolites. In the present study, the feasibility of rat hair as a QCM was examined for its application in the determination of methamphetamine (MA) and amphetamine (AP) in human hair. MA was administered to lean Zucker rats, from which only pigmented hair was collected for the preparation of a QCM. The rat hair was then washed, homogenized and finally bottled. Both homogeneity and stability were examined in order to demonstrate the suitability of rat hair as a QCM in hair drug analysis. The concentrations of MA and AP in each bottle were determined using extraction with 1% HCl in methanol at 38°C followed by gas chromatography/mass spectrometry after derivatization with trifluoroacetic anhydride. Furthermore, the prepared QCM was used in an inter-laboratory quality assurance program. In the homogeneity test, no significant difference was observed between bottles of the QCM. The statistical results also showed no significant trends in stability for three months at room temperature. An inter-laboratory quality assurance program was also performed successfully using this material. Thus, rat hair will be useful as an alternative QCM sample for the determination of a variety of drugs and their metabolites in human hair.

Hair Mineral Analysis in Women with Telogen Effluvium

( Mi Soo Choi ),( Seung Phil Hong ),( Myung Hwa Kim ),( Byung Cheol Park ) 대한피부과학회 2018 大韓皮膚科學會誌 Vol.56 No.1

Background: Imbalances in trace elements have been associated with many forms of alopecia and other hair problems. Telogen effluvium (TE) is a type of hair loss showing nonpatterned shedding of terminal hair. TE might be the result of various changes in body condition such as labor, weight loss, surgery, or stress. These conditions could induce the deficiency or excess of trace elements in tissue such as hair. Objective: The objective of this study was to find differences in trace elements between a female TE group and a normal group using a hair mineral analysis (HMA) method. Methods: Medical records including hair mineral analysis results of 80 women with TE and 35 healthy normal women were retrospectively reviewed. Results: Bismuth (Bi), iron (Fe), titanium (Ti), and zinc (Zn) levels in the TE group were significantly decreased compared to those in the normal group. The median value of Zn in the TE patients' group was 50.98 μg/g, and that of the normal group was 76.19 μg/g (p<0.01). Fe was also significantly decreased in TE patients (50.98 μg/g) compared to the normal group (74.04 μg/g). The level of Zn and Fe in TE patients was significantly lower compared to that in the normal group based on hair mineral analysis results (p<0.01). There was a weak tendency that cobalt (Co), barium (Ba), mercury (Hg), lithum (Li), and tin (Sn) were lower and selenium (Se) was higher in the TE group than in the normal group (p<0.05). Conclusion: In conclusion, lower levels of Zn and Fe might be related to the hair loss process in women with TE. (Korean J Dermatol 2018;56(1):36∼41)

A comparative study on the concentrations of 11-nor-Δ⁹-tetrahydrocannabinol-9-carboxylic acid (THCCOOH) in head and pubic hair

Han, E.,Choi, H.,Lee, S.,Chung, H.,Song, J.m. Elsevier Sequoia 2011 Forensic Science International Vol. No.

In this study, the concentrations of 11-nor-Δ<SUP>9</SUP>-tetrahydrocannabinol-9-carboxylic acid (THCCOOH) in pubic, axillary and beard hair were measured and the correlation between the concentrations of THCCOOH in head and pubic hair from same cannabis users were evaluated. The papers on body hair analysis for THCCOOH were rarely found although police officers submit body hair as a complimentary specimen to forensic laboratories in case cannabis users had no hair. Head, pubic, axillary, and beard hair were collected. All hair samples were cut into 0.5mm segments and decontaminated with methanol, digested with 1mL of 1M NaOH at 85<SUP>o</SUP>C for 30min and extracted in 2mL of n-hexane:ethyl acetate (9:1) two times after adding 1mL of 0.1N sodium acetate buffer (pH=4.5) and 200μL of acetic acid followed by derivatization with 50μL of PFPA and 25μL of PFPOH for 30min at 70<SUP>o</SUP>C. The extracts were analyzed using gas chromatography tandem mass spectrometry operating in negative chemical ionization mode (GC/MS/MS-NCI). We determined the concentrations of THCCOOH in both pubic and head hair. The concentrations of THCCOOH in pubic hair were higher than those in head hair. We also evaluated the concentrations of THCCOOH in body hair (pubic, axillary and beard hair) and head hair according to the positive/negative urine test results. There was no statistically significant difference in the concentrations of THCCOOH in head and body hair according to urine results.

Role of hair pigmentation in drug incorporation into hair

Yu, Hyerim,Jang, Won-Jun,Jang, Jung-Hee,Park, Byoungduck,Seo, Young Ho,Jeong, Chul-Ho,Lee, Sooyeun Elsevier 2017 Forensic Science International Vol.281 No.-

<P><B>Abstract</B></P> <P>Hair analysis has notably expanded its application as a bio-monitor for drug or toxicant exposure. Hair pigmentation is proposed as a major factor affecting drug incorporation into hair; however, the mechanisms underlying the incorporation of drugs into hair are still unclear. In the present study, the effect of hair pigmentation on drug incorporation into hair was examined using rats carrying hair with different melanin status and human cells (SK-Mel-28 cells, HaCaT cells and the co-cultured HaCaT cells with SK-Mel-28 cells) representing the main pigmentary unit in hair. Tramadol, a synthetic opioid analgesic, was selected as a model drug. The distribution of tramadol and its phase I (<I>O</I>-desmethyltramadol [ODMT], <I>N</I>-desmethyltramadol [NDMT] and <I>N</I>,<I>O</I>-didesmethyltramadol [NODMT]) and phase II metabolites (ODMT-glucuronide and NODMT-glucuronide) was investigated in non-pigmented and pigmented hair from Long–Evans rats. Moreover, the incorporation levels of ODMT and ODMT-glucuronide were compared in hair cells. The concentrations of tramadol and its phase I metabolites were significantly higher in pigmented rat hair while those of phase II metabolites did not showed any consistent significant difference depending on the status of hair pigmentation. ODMT was taken up to a greater extent than ODMT-glucuronide by SK-Mel-28 cells, HaCaT cells and the co-cultured HaCaT cells with SK-Mel-28 cells. Notably, the incorporated level of ODMT was higher in SK-Mel-28 cells than HaCaT cells and the concentration difference of ODMT was significantly larger than that of ODMT-glucuronide. This study clearly demonstrated that hair pigmentation played a role as a facilitating factor for the incorporation of basic compounds and provided insight into the drug incorporation process into hair.</P> <P><B>Highlights</B></P> <P> <UL> <LI> The role of hair pigmentation in drug incorporation into hair was investigated. </LI> <LI> Rats carrying hair with different melanin status were used. </LI> <LI> Human cells representing the main pigmentary unit in hair were used. </LI> <LI> Hair pigmentation is a facilitating factor for the incorporation of basic compounds. </LI> <LI> The cell study provided insight into the drug incorporation process into hair. </LI> </UL> </P>
