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.

This study describes Hg(OTf)2 as a new and efficient catalyst for various organic synthesis reactions, including alkyne hydration and C–C bond forming cyclizations.

The study found that cyproterone acetate could be released over 15 days using coconut oil mixed with certain wax inhibitors, though further safety studies are needed.

This study suggests that 3,4,5-tri-O-caffeoylquinic acid activates β-catenin to enhance pigmentation in mouse hair follicles, human melanocytes, and melanoma cells during the hair cycle's growth phase.

Oxidation changes the structure of hair protein filaments, causing them to compact and rearrange.

This review discusses the use of supercritical carbon dioxide for extracting rice bran oil, noting its advantages over conventional methods for preserving nutrients and antioxidants, but provides no new experimental results.

This study reports the crystal structure and geometric parameters of a modified Finasteride derivative, highlighting significant differences in dihedral angles compared to its solvated analog and computational models.

This study reported that derivatization with 5-butylpicolinic acid improved the sensitivity for detecting testosterone and DHT in saliva using LC-ESI-MS/MS, with minimal interference from the saliva matrix.

This study reports a novel method for synthesizing substituted hydantoins, including the anticonvulsant drug ethotoin, using safer reagents and fewer steps compared to conventional protocols.

This review examined the diverse therapeutic potentials of cannabinoids, highlighting their applications in pain, neurological, and cancer treatments, and emphasized the benefits of biodegradable polymers in improving drug delivery; however, further clinical trials are needed to fully explore these potentials.

This study found that thioglycolic acid molecules in hair treatments are primarily located in intrafibrillar unordered areas, where they redistribute disulfide bonds.

In this study, researchers tested a tea leaf ethanol extract (Camellia sinensis) hair tonic and found it increased average hair growth compared to positive and negative controls over 28 days, but exhibited some instability and inhomogeneity after accelerated testing.

This study found that diphlorethohydroxycarmalol significantly increased prostaglandin $E_2$ synthesis in HaCaT human keratinocytes by upregulating COX-1 and COX-2 expression, suggesting potential benefits from elevated $PGE_2$ production.

This study found that hydrogenated palm oil effectively conditions damaged hair by preventing water-induced swelling, with TOF-SIMS analysis showing that its component tripalmitin penetrates the hair's cuticle and outer cortex.

This study found that a single application of TCDD on the skin of hairless mice altered epidermal differentiation, changing keratin expression patterns similarly to a known tumor promoter.

In this study, cinnamic acid was found to enhance hair growth in human dermal papilla cells and hair follicle organoids by activating oxytocin signaling, suggesting its potential for developing hair growth-promoting products.

In this study, optical coherence tomography was used to produce 3D images of human hair, revealing that after chemical treatment with ammonium thioglycolate, the main hair structures were not identifiable due to damage.

This study concluded that a hair-nourishing formulation combining virgin coconut oil and 4% chilli oil significantly enhanced hair growth in white rats over a 21-day period, while also exhibiting good physical stability under varying storage conditions.

In this in-vitro study, researchers found that shampoo-induced coacervates structurally resemble cationic polymers and contain anionic surfactants that may stimulate the scalp upon exposure to water.

This study found that waving virgin human hair with thioglycerol at pH 9.0 using ammonia solution caused less damage than using thioglycolic acid, while maintaining good waving efficiency.

This study found that Hataedock may alleviate atopic dermatitis symptoms in mice by maintaining skin homeostasis and improving skin barrier formation through the endocannabinoid system.

This study evaluated the resin oil of Copaifera officinalis L., identifying 64 compounds and developing validated analytical methods for quality control, and formulated a stable pharmaceutical foam, laying groundwork for potential clinical applications of copaiba oil.

This study suggests that coffee ground extract may accelerate hair growth in rabbits, potentially due to its caffeine content.

This study found that stimulating the olfactory receptor OR2A4/7 with cyclohexyl salicylate promoted human hair growth and increased progeny of hair follicle epithelial stem cells in an ex vivo setting.

This study found that while 11-oxyandrogens do not aid in diagnosing PCOS, they correlate with hirsutism severity, and 11-ketotestosterone levels decrease with combined oral contraceptive therapy.

This review summarizes research on cannabinoids like CBD and THCV, reporting that they improve hair growth in patients with androgenetic alopecia when applied topically, with CBD showing a dose-dependent effect.

This study found that high-speed optical coherence tomography may be a promising non-invasive tool for analyzing human hair conditions.

This study identified several active compounds in Houttuynia cordata and found that most demonstrated significant antioxidant and acetylcholinesterase inhibitory activity, potentially useful for developing functional tea products.
