This study found that hair samples from chronic tramadol and cannabis users showed positive drug presence for 3-4 months and 6-7 months, respectively, after discontinuation.

This study found that concentrations of THCCOOH in hair do not correlate well with self-reported cannabis use due to inaccuracies in the self-reported data, but it provides preliminary insights into usage patterns.

This paper discusses advancements in forensic hair analysis, emphasizing a novel DART–HRMS method that improves the accuracy and efficiency of detecting drug use timelines.

This review highlights how forensic drug analysis in hair using modern instrumental techniques offers advantages such as easy sample collection and chronological tracking of drug use, emphasizing its value for law enforcement and other applications.

This study concluded that standard decontamination procedures do not fully remove external contamination from post mortem hair specimens, which complicates using hair analysis to assess long-term drug exposure.

Hair testing is a reliable method for detecting workplace drug use when done with proper sample preparation and confirmation.

This study found that standard decontamination procedures may not fully remove external contamination in post mortem hair specimens, complicating the interpretation of drug detection in such samples.

In this research on cinnamon and virgin coconut oil hair tonics, F2 and F3 demonstrated stable physical properties and mild irritation potential, while formula 1 remained non-irritating but less stable regarding pH and viscosity.

This study observed that a polyherbal hair oil made from virgin coconut oil and extracts of nine different herbs demonstrated effectiveness in promoting hair growth with a cooling effect and no reported side effects, based on various evaluated properties.

This study concluded that THC and THCA incorporate into hair by a mechanism independent of hair pigmentation, likely influenced by indirect deposition via sebum and skin.

This study developed a straightforward HPTLC method for detecting nicotine and cotinine in human plasma and urine, concluding that liquid-liquid extraction with methanol: chloroform: ammonia achieved optimal separation and is applicable for forensic analysis of lethal nicotine intoxication.

This study found that the new HCC additive enhances the permeation of pigments and active ingredients into hair, suggesting potential use in developing functional cosmetic hair products.

This study found that treatment with the polyphenolic compound TCQA activated β-catenin, promoting hair regrowth and the initiation of the anagen phase in mice and human dermal papilla cells.

This study found that in vitro heat straightening of hair reduced THC and cocaine concentrations but increased CBN and BZE levels, suggesting heat conversion of these substances.

This study observed that the degradation product PTeCA significantly increased in hair treated with oxidative cosmetics, suggesting it could be a reliable marker for detecting such treatments, with a proposed PTCA cut-off value using PTeCA as the gold standard.

This study investigated the cytotoxic effects of DHA derivatives on cancer cell lines and found that didocosahexaenoin was the most potent, inducing apoptosis and producing reactive oxygen species in PC3 prostate carcinoma cells.

In this study, a hair tonic containing fragrant pandan leaf extract and virgin coconut oil was formulated and evaluated, with most variations demonstrating physical stability except for one formulation, which showed instability in the specific gravity test.

This study reports the crystal structure of C28H32O5, revealing its monoclinic symmetry, unit-cell dimensions, and molecular conformation.

This study demonstrated that HOXC13 directly influences hair keratin gene expression by binding to specific DNA motifs, suggesting its role in early hair follicle differentiation.

This study found that coconut oil may protect the cuticle of chemically treated hair, which tends to be damaged compared to untreated hair.

Coconut oil boosts testosterone but doesn't fully trigger reproductive maturity in pufferfish.

This study suggests that while hair analysis using GC-MS is a sensitive method for detecting cocaine ingestion, it may not reliably indicate the amount, timing, or duration of drug use due to interindividual variability and multiple incorporation mechanisms.

This study found that using a bicomponent reduction system with TGA and DTDG for hair straightening limited hair damage by forming only thiol groups, while a TGA-only system formed more damaging mixed disulfide groups.

This study found that coconut oil significantly increased the tensile strength of twisted hair fibers due to its ability to penetrate the hair core, in contrast to mineral oil.

This study developed a rapid, precise, and specific chromatographic method to measure alpha-tocopheryl nicotinate in cosmetics, using alpha-tocopheryl acetate as an internal standard.

In this study, the synthesis of C-4 and C-6 bridged haptens of 11 alpha-hydroxyprogesterone revealed an unexpected formation of a C-4 substituted product using a 6-bromo derivative, contrary to prior reports.

In this study, all stereoisomers of cyoctol were synthesized and tested, revealing that contrary to initial patent claims, cyoctol does not function as an anti-androgen.

This study observed that regular coconut oil users have significantly reduced hair irregularities compared to non-oil users, as quantified by a new "hair protection factor" metric, highlighting coconut oil's potential in minimizing hair damage.

In this experimental study using rabbits, the researchers evaluated hair tonic formulations containing cinnamon essential oil and virgin coconut oil, finding that formula 3 had hair growth activity exceeding the positive control, though overall growth activity differences were not statistically significant.
