This study outlined modern approaches for using cosmeceuticals in trichology, emphasizing evidence-based medicine, personalized care, and patient safety. It proposed the H.A.I.R. model as a universal algorithm for trichological programs and suggested new educational and practical tools for specialists in trichology and aesthetic medicine.

This study suggests that hair cortisol measurement could serve as an alternative diagnostic method for Cushing’s disease, showing acceptable concordance with urinary free cortisol despite differing evaluated periods.

In this study, researchers found that while chest hair can be a reliable alternative to scalp hair for ethylglucuronide testing, seasonal factors may affect concentration levels and should be considered in result interpretation.

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 the pH-sensitive hydrogel HECHA13, containing isoliquiritigenin, effectively inhibited the growth of Propionibacterium acnes and showed promise for transdermal delivery in acne treatment.

This study found that while ethinyl oestradiol and cyproterone acetate effectively treated hirsutism in 90% of patients, 80% experienced relapse within six months after stopping treatment, suggesting long-term use is necessary.

Ethinylestradiol/Chlormadinone Acetate is a safe and effective birth control pill that also helps regulate menstrual cycles, reduces period pain, and treats certain skin and hair conditions.

This study presents a new method using UPLC-ESI-MS/MS for analyzing the constituents of a medicinal herbal complex extract, which includes herbs traditionally used to prevent hair loss and promote hair growth; no clinical results were reported.

This article describes the Australian Medicines Handbook as a compact, readable, and comprehensive drug reference guide for Australian practitioners, but it does not present new research findings.

The method effectively analyzes human hair proteins, especially nonfilamentous ones.

The researchers concluded that after the 2013 EMA recommendation, there was an overall reduction in CPA/EE prescriptions, but no substantial change in patient diagnoses or potential concurrent hormonal contraceptive use.

Hair cortisol concentration partly reflects HPA axis regulation but doesn't capture all its complexities.

This study describes new devices, "HairMeasure" and "Scalp Zone Identifier," which offer an economical method to calculate Hair Mass Index without disposable materials.

In this study, the authors developed a medicated face mask using electrospun fibers to deliver the active compound Eflornithine hydrochloride for managing hirsutism. The mask showed promising drug release characteristics, a high safety profile, and reduced hair growth in mice.

This review discusses the use of hair cortisol concentration as a marker for chronic stress and long-term cortisol secretion in animals, highlighting its benefits and the need for standardized sampling protocols.

This study utilized a UHPLC-HRMS method to identify eight active pharmaceutical ingredients, such as ketoconazole and minoxidil, in 26 out of 100 analyzed cosmetic products.

This study developed a new measurement procedure using isotope dilution-liquid chromatography-tandem mass spectrometry for accurate quantification of DHEAS in human serum or plasma, demonstrating high selectivity, sensitivity, and low measurement uncertainty, making it suitable for routine standardization and clinical evaluation.

This study developed a micellar electrokinetic capillary chromatography method for determining minoxidil in Rogaine and generic products, offering a simple and efficient alternative to HPLC.

The researchers reported that the rat Hershberger assay reliably detected endocrine-disrupting effects of finasteride, procymidone, and 17α-methyltestosterone, validating the assay's sensitivity for identifying hormonal activity.

This report presents a case of hereditary elliptocytosis in a 37-year-old woman with iron deficiency anemia, identifying a high percentage of elliptocytes in her blood after treatment.

This review highlights that Cyproterone acetate combined with ethinylestradiol is highly effective for treating severe acne and hirsutism in women with hyperandrogenism, and it also provides benefits for cycle control and mood improvement, according to the analysis of 78 studies.

This study found that the Bioengineered Exosomal Hair Growth Factors Complex (BEHC™) enhanced human follicle dermal papilla cell proliferation and reduced inflammatory markers in vitro, while significantly decreasing hair shedding and increasing hair density among participants with androgenetic alopecia in an open-label clinical study.

The birth control pill containing ethinylestradiol and chlormadinone may help treat acne and other skin and hair conditions related to hormones.

This study found that human TMEM2 does not function as a hyaluronidase but is involved in regulating hyaluronan metabolism.

In this study, the reconstructed skin epidermal model derived from hair follicles showed gene expression and enzyme functionality consistent with native human skin, suggesting its viability for studying skin metabolism and potential toxicity of dermo-cosmetic ingredients.

Hair fibers break by cuticle cell slipping, shape changing, cuticle fraying, and surface cracking when stretched under specific conditions.

This study discusses using SEM/EDX for elemental analysis of hair samples in forensic science but notes challenges in detecting certain trace elements from raw hair.

This study aimed to determine the phenolic compound composition in Equisetum arvense stem extracts using HPLC, as the plant is commonly used in cosmetics for skin and hair care, but results are not reported here.

This study found that anionic HSES achieved high complexation efficiencies with various steroids, significantly enhancing their solubility, while specific β-cyclodextrin thioethers showed selective binding to testosterone and estradiol.

This report summarizes data from The Netherlands' cosmetovigilance system from 2009-2014, finding that facial and hair products commonly caused undesirable skin reactions like erythema and itching, with severe cases occasionally involving hair loss and respiratory issues.
