This study found that microfibrils play a crucial role in shaping permanent waves by thioglycolic acid, and treating damaged hair with hydrolyzed keratin improved both waving efficiency and hair damage.

This review discusses the chemical processes involved in hair styling and straightening and reports no new results; the authors highlight pregnancy safety with hair treatments during pregnancy.

This study reports that prolonged UV irradiation causes progressive damage to the hair's keratin structure, leading to increased surface roughness, cuticle destruction, and decreased tensile strength in young women’s hair.

This study utilized a fluorescence probe to evaluate cysteine formation on hair fibers, finding that optimal fluorescence emission occurred at pH 4.5.

Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.

Certain skin drugs and topical agents, including some natural extracts and fragrances, can cause allergic reactions. Some hair dyes and extensions, as well as minoxidil, a hair growth treatment, can also cause allergies. Botulinum toxin A can effectively reduce sweat but may have temporary side effects.

The authors concluded that low energy laser therapy may serve as a useful complementary treatment for skin diseases such as lichen planus, infectious finger pulpits, scalp alopecia, and crural ulcers.

In this study, researchers found that follicular and epidermal transglutaminases are biochemically and immunologically distinct, suggesting the possibility of selectively modifying hair or epidermal proteins.

This study found that a unique transglutaminase in guinea pig hair-follicles, distinct from liver transglutaminase, likely plays a role in forming protein cross-links via ε(γ-glutamyl)lysine bonds.

In this study, researchers observed that cosmetic peroxide bleaching causes oxidative damage and protein loss in human hair, not only affecting the cuticle but also deeper cortical structures, correlating with bleaching severity.

The new compounds may be more effective and cheaper than current treatments for conditions like baldness.

This study reports that the dye peri-xanthenoxanthene (PXX) can act as an efficient photocatalyst for various radical reactions, including complex dual catalytic processes and the synthesis of an investigational drug intermediate.

This study describes the structure and composition of the epidermal horny layer in elephant seals, noting that its keratinized cells are attached without a specialized fission zone, differing from the sloughing mechanism in reptiles.

This study examined the microscopic characteristics of hair or feather in five animal drug components of the Shenrongbian pill, identifying distinctive medulla cell shapes and hair cuticle patterns for each component.

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 found that microneedles based on polyphosphazene with green tea polyphenols significantly enhanced wound healing in a diabetic rat model.

In this study, researchers found that a scallop adhesive protein (Sbp9 Δ) forms strong adhesive coatings via disulfide-sticker strategies, which also promote hair regeneration in mouse models by activating Wnt signaling and enhancing angiogenesis, proving more effective than minoxidil for androgenetic alopecia.

Disulfide bonds are crucial for hair structure during keratinization.

This review outlines the adverse effects of glucocorticoid excess on bones, adipose tissue, brain, and skin, with a focus on the Wnt/β-catenin pathway, and reports no new research findings.

In this study, PRP administration in rabbit tibia bones with segmental defects improved bone healing scores and advanced bone development stages compared to the control group.

This study found that the vitamin D receptor in lampreys, which lack bones and hair, binds 1,25-dihydroxyvitamin D3 and may function to induce enzymes for detoxifying substances.

This study suggests that TGase 3 may contribute to hair fiber scaffolding by forming specific isopeptide bonds between keratin intermediate filaments and keratin-associated proteins.

Androgens affect behavior, hair, bones, muscles, and the heart, and can be used to treat certain conditions.

In this study, researchers mapped cysteine accessibility in wool keratins and KAPs, revealing that certain cysteines in keratin end domains and Types I and II rod domains are accessible and likely involved in forming disulfide bonds.

This study found that chemically modifying hair with 2-iminothiorane hydrochloride improved the permanence of hair setting without damaging the hair by increasing disulfide bonds.

This review highlighted the pharmacological potential of Mor, noting its protective effects on the kidneys, liver, bones, nervous system, heart, digestive system, skin, and lungs, as well as its anti-obesity and anti-inflammatory properties, revealing areas for future research.

This review provides a comprehensive overview of apoptosis-related molecules in head development, highlighting caspases' roles and associated abnormalities in tissues like the brain, sensory organs, skin, and bones, without reporting new results.

This review reports that while botulinum toxin shows potential mechanisms for treating androgenetic alopecia, recent high-quality trials found no significant hair density improvement compared to placebo, indicating it can't yet replace traditional treatments.

This study found that CMAD wool keratin may protect human hair from damage during repeated bleaching and permanent waving treatments.

This article outlines a randomized trial to evaluate whether preoperative botulinum toxin administration can improve hair transplantation outcomes by reducing ischemia-induced graft failure.
