This review suggests that multifunctional cosmetic systems, particularly HIVEN Curl Code ®, may help control frizz and maintain curl definition in highly curly hair by utilizing various conditioning and biofunctional ingredients.

This study found that hair sample weight was a better predictor of hair cortisol concentration than hair protein concentration, suggesting that using the standard cortisol-to-weight ratio is more suitable for measuring cumulative cortisol activity in scalp hair.

This study developed a validated method for analyzing minoxidil in hair care cosmetics, demonstrating good precision and recovery rates.

In this study, mouse skin exposed to cigarette smoke condensate exhibited increased epidermal thickness and ODC expression, with some changes persisting after exposure ended, suggesting potential for tumor promotion and measurement discrimination.

Researchers created a reliable method to measure dexpanthenol and resorcinol in hair products.

This review discusses the pharmacology and toxicology of cyclooxygenase in skin, highlighting its role in inflammation, wound healing, and tumorigenesis, without presenting new clinical results.

This study found that torsional measurements can effectively distinguish the effects of hair care products on the cuticle versus the cortex of hair fibers, unlike tensile measurements.

This study observed that repeated perm treatments decrease disulfide bonds in hair due to their conversion largely into cysteic acid, affecting the waving efficiency depending on the reduction agent used.

This study found that compound 3, a tetrahydropyridoindole carboxymethylated at position 5, significantly inhibited sorbitol accumulation in both rat eye lenses and tissues affected by diabetes, indicating its potential as a lead compound for ALR2 inhibition.

A new antiandrogen compound was made and its detailed three-dimensional shape was described.

This study demonstrated that using a mass spectrometry imaging technique, researchers were able to visualize the incorporation of argan, avocado, and coconut oils into hair fibers, suggesting their potential in cosmetic and alopecia treatments by confirming oil absorption and fiber modification.

This study observed that treating human hair with NaOH led to partially removed cuticles, resulting in better fiber cohesion and mechanical properties similar to wool, unlike bleach or formic acid treatments, which weakened the fibers.

Caffeine in hair might help identify people, but it's not always reliable.

This study suggests that the COX-2 enzyme plays a role in hair follicle biology, as transgenic overexpression in mice induced hair follicle cycling disturbances and alopecia, which was mitigated by COX-2 inhibition.

This article reviews the genetic and phenotypic characteristics of Trichothiodystrophy and discusses the associated DNA repair defects, but does not report new clinical findings.

This study found that treating hair with aqueous KCN converts disulfide bonds to monosulfide crosslinks, affecting the elasticity and crosslink distribution in hair microstructures.

This study reported that the treatment of hair with glyoxylic acid straighteners causes major conformational changes within the hair fiber due to interactions between carbonyl and keratin components.

Trichoscopy helped diagnose and treat a child's fungal scalp infection by spotting specific hair shapes.

This study found that in hamster flank organs, 17βC inhibited enlargement caused by topical testosterone but not by DHT, suggesting potential use in androgen-related skin disorders like acne.

This study found that hydrophilic carbon dots (Lys-CA-CDs) induced bovine serum albumin to form more wormlike fibrils, while inhibiting hen egg white lysozyme from forming hair-like fibrils.

This study found that the cocrystal of mycophenolic acid with isonicotinamide significantly improved solubility and dissolution rate, while two other cocrystals showed decreased performance in these areas.

Castor oil is suitable for use in hair care products.

This study found that hydroxycinnamate derivatives, especially a compound named 10a, effectively inhibited SRD5A1 activity and protein expression in cell assays, suggesting potential for treating androgen-related conditions.

This review discusses the challenges in diagnosing different causes of adult androgen excess and outlines current screening and management strategies but reports no new findings.

In this study, EPC-K, a compound with antioxidant and moisturizing effects, was found to decompose significantly under certain conditions, impacting its stability in quasi drug hair-growing products.

This study developed a faster method for analyzing fatty acid ethyl esters in hair to help detect alcohol consumption levels, showing potential for applications in forensic and clinical settings.

This study found that the cross-section trichometer is a promising tool for measuring hair mass index with high reproducibility, suggesting potential clinical and research applications.

A neurosteroid can reduce caffeine-induced anxiety in rats.

This study introduced a simple and reliable in vitro assay capable of large-scale simultaneous screening of hair growth-promoting compounds using a 3D co-culture system of human dermal papilla and outer root sheath cells.

This study found that both new and old formulas of DCP for treating alopecia areata resulted in similar hair regrowth, but tolerance was significantly better with DCP in isopropanol.
