This study aimed to describe the gross phytochemical constituents of Todaro gel and evaluate the characteristics and quality of lab-made hair washing formulations prepared from the gel to show its potential in formulating hair washing shampoos. gel mass was prepared from mature, healthy leaves collected from natural stand. Samples of 100% methanol extract of the gel were subjected to standard phytochemical screening and gas chromatography-mass spectroscopy (GC-MS) analysis. Five hair washing formulations (Fs) were, likewise, prepared by mixing 4.0-10.0 mL of gel with one (0.05 mL) to two (0.10 mL) drops of six synthetic and natural ingredients, namely, coconut oil, jojoba oil, olive oil, pure glycerin oil, lemon juice, and vitamin E. The gel to the total ingredient ratios (v/v) of the five formulations were 93 : 7 (F), 94.5 : 5.5 (F), 96.4 : 3.6 (F), and 96.6 : 3.4 (F and F). The formulations were evaluated using sensory inspection and common physicochemical methods. The phytochemical screening and GC-MS analysis revealed that gel is the source of important chemical constituents used in the formulation of shampoos and similar products including saponins, capric acid, lauric acid, myristic acid, palmitic acid, linoleic acid, stearic acid, and phytol. Lab-made hair washing formulations, especially those with 96.4-96.6% gel, were found to have similar characteristics and qualities with a common marketed shampoo. All the formulations were turbid with characteristic odor as the marketed shampoo. The pH values of the hair washing formulations (6.4-4.6) were comparable to those of the marketed shampoo (6.7). Formulations with higher proportion of gel had better foam stability, higher solid content (26-29%), higher surface tension (33-38 dynes/cm), shorter wetting time (150-160 sec), equivalent viscosities (26.45-26.73 poise), and conditioning performance than the marketed shampoo. These findings demonstrate that gel mass can be used in the formulation of good-quality hair washing shampoos. We recommend future studies that aim to develop the phytochemical profile of the plant and a refined protocol of hair washing shampoo formulation.

Metal polyphenolic networks (MPNs) are becoming more and more attractive for nontoxic hair dyeing, but their coloring effect is not satisfactory because of the limited interfacial deposition and the absence of internal deposition. Moreover, there is a lack of understanding of the driving factors of the interfacial deposition of MPNs on hair. Herein, we develop a simple yet efficient strategy that transforms disulfide bonds of the hair into thiol groups by thioglycolic acid (TGA) to highly enhance the coloring effect of MPNs at a low temperature.

Background: Scalp seborrheic dermatitis (SD) is a chronic, recurrent inflammatory skin condition associated with scalp sebum secretion and dysbiosis.
Aims: The aim of this study is to evaluate the efficacy and safety of a topical salicylic acid/piroctone olamine/zinc salt of L-pyrrolidone carboxylate (Zinc PCA) scalp pre-application gel in combination with a salicylic acid/piroctone olamine/antimicrobial peptide cleansing lotion for the treatment of moderate to severe scalp SD.
Patients/methods: In this prospective cohort study, 20 patients with moderate to severe scalp SD were treated with a combination of the scalp pre-application gel and cleansing lotion for 4 weeks (one tube of the pre-application gel per week and the cleansing lotion used every 1-3 days depending on the frequency of hair washing).

Background: Buprenorphine (BUP) use is prevalent in pregnant women with opioid use disorder (OUD). Drug monitoring during pregnancy is critical for optimizing dosing regimen and achieving the desired clinical outcomes. Hair can be used as a critical biological matrix for monitoring long-term exposure to drugs.

Purpose: Distribution and abuse of imidazole-derived γ-aminobutyric acid (GABA) agonists, such as etomidate and metomidate, and their analogs have been encountered frequently especially in China. The aim of this study was to identify etomidate, metomidate, propoxate, and isopropoxate more accurately by establishing a gas chromatography-mass spectrometry (GC-MS) and liquid chromatography tandem mass spectrometry (LC-MS/MS) method and applying it to real forensic cases.
Methods: One mg of the seized powder was dissolved in 1 mL of methanol, and subjected to GC-MS and LC-MS/MS.

Hair analysis for drugs has become extensively used for forensic investigation in recent years. To best interpret hair drug content in post-mortem conditions, the extent of external contamination by biological fluids, such as blood, must be taken into account to avoid false positive results. The present study evaluated opiates and opioids incorporation into hair from blood containing different concentrations of morphine (MOR), 6-mono-acetyl morphine (6-AM), codeine (COD), dihydrocodeine (DHC), tramadol (TRA), oxycodone (OXY), methadone (MET), 2-ethylidene-1,5-dimethyl-3,3- diphenyl pyrrolidine (EDDP), buprenorphine (BUP) and norbuprenorphine (NBUP).
