research The forensic limits of hair drug testing: a critical assessment of drug intake and hair concentration relationships
Hair analysis can confirm drug use but can't accurately measure how much was taken.
research Hair Drug Testing Routine in Many Clinical and Forensic Applications
Hair testing is effective for detecting long-term drug use.
research Hair follicle testing-an alternative to urinalysis for drug abuse screening
Hair follicle testing is more reliable and effective for drug screening than urinalysis.
research In vitro hair follicle growth model for drug testing
Researchers developed a new method to test hair growth drugs and found that adult cells are best for hair growth, but the method needs improvement as it didn't create mature hair follicles.
research Influence of the cosmetic treatment of hair on drug testing
Cosmetic hair treatments like bleaching and dyeing reduce drug levels in hair samples.
research Geometric classification of scalp hair for valid drug testing, 6 more reliable than 8 hair curl groups
A 6-group hair classification is more reliable for drug testing than an 8-group system.
research Ocfentanil testing in hair from a fatality case: Comparative analysis of a lock of hair versus a single hair fiber
Both a lock of hair and a single hair strand can show chronic drug use, but at least six single hairs are needed for accurate results.
research Improved forensic hair evidence for drugs of abuse by mass spectrometry
Forensic hair analysis for drugs is now more reliable and accurate.
research (Un)targeted Scanning of Locks of Hair for Drugs of Abuse by Direct Analysis in Real Time–High-Resolution Mass Spectrometry
A new method can quickly and accurately detect drugs in hair.
research Stability of opiates in hair fibers after exposure to cosmetic treatment
Cosmetic treatments like bleaching and perming can greatly reduce opiate levels in hair, possibly leading to false-negative drug tests.
research Advancements in hydrogel-based design and applications of hair follicle organoids
Hydrogel-based hair follicle organoids could help treat hair loss and improve drug testing.
research Hair multiplication with dermal papilla like tissue containing human dermal papilla cells
Injecting lab-grown hair cells into the scalp can regrow hair.
research W6: Novelties in hair analysis and interpretation issues
Hair analysis can be unreliable due to external contamination and varying drug concentrations.
research Can an in vitro hair drug model be developed using dermal papilla cells alone?
Dermal papilla microtissues could be useful for initial hair growth drug testing.
research Keratin film made of human hair as a nail plate model for studying drug permeation
Keratin films from human hair can potentially replace human nail plates for drug testing.
research Festschrift in honor of the 65th birthday of Dr. Howard I. Maibach
Antiyeast treatments work better for seborrheic dermatitis than steroids, and other findings include increased skin bacteria under plastic wrap, a nasal cell defect in Staphylococcus aureus carriers, quick resolution of certain skin reactions, high rubber latex allergy in spina bifida patients, and glyceryl monopentadecanoate's effectiveness for male hair loss.
research Generation of Skin Organoids: Potential Opportunities and Challenges
Skin organoids from stem cells could better mimic real skin but face challenges.
research 27th Meeting of the Society of Hair Testing (SoHT)
Hair testing is crucial for forensic science and public health.
research Issues About Axial Diffusion During Segmental Hair Analysis
Wait 4-5 weeks after drug use before hair testing and cut hair into three segments to confirm single drug exposure.
research The C3H/HeJ mouse and DEBR rat models for alopecia areata: review of preclinical drug screening approaches and results
Both mouse and rat models are effective for testing alopecia areata treatments.
research Emerging Diagnostic and Therapeutic Potentials of Human Hair Proteomics
Hair protein analysis could improve medical testing and understanding of hair characteristics.
research Next generation human skin constructs as advanced tools for drug development
Advanced human skin models improve drug development and could replace animal testing.
research Current Protocols: Alopecia Areata Mouse Models for Drug Efficacy and Mechanism Studies
The C3H/HeJ mouse model is useful for studying and testing treatments for alopecia areata.
research Application of 3D Bioprinting Technology for Tissue Regeneration, Drug Evaluation, and Drug Delivery
3D bioprinting is useful for making tissues, testing drugs, and delivering drugs, but needs better materials, resolution, and scalability.
research Human hair follicle organ culture: theory, application and perspectives
Human hair follicle organ culture is a useful model for hair research with potential for studying hair biology and testing treatments.
research Engineering immune-competent hair follicle microphysiological systems: from organoid assembly to dynamic immune modelling
Hair follicle systems are being engineered to better mimic natural hair follicles for studying hair disorders and testing treatments.
research Human Hair as a Testing Substrate in the Era of Precision Medicine: Potential Role of ‘Omics-Based Approaches
Human hair shows promise for non-invasive medical testing, but more research is needed to standardize its use.
research Drug eruptions in dermatology
Skin reactions to drugs are common and can be deadly, usually requiring stopping the drug and may be better prevented with genetic testing in the future.
research The potential for occupational exposure of veterinarians to ketamine resulting in positive drug tests
Veterinarians could test positive for ketamine from work exposure, not just substance abuse.
