This study found that washing hair after reduction in a permanent waving process allows for significant reformation of disulfide cross-links, enhancing the strength and elasticity of hair fibers.

This study demonstrated that urea significantly accelerates the diffusion of poly(ethylene imine) into bleached human hair by increasing the diffusion coefficient twofold.

This study found that using poly(ethylene imine) as a counterion reagent improved the colorability and shampoo fastness of bleached human hair when dyed with an acid dye.

This article discusses methods to enhance finasteride delivery to scalp skin using heat and chemical penetration enhancers and reports no new experimental findings.

This study found that short durations of heat and specific chemical penetration enhancers significantly improved the delivery of finasteride to human scalp skin and hair follicles.

This study found that finasteride microemulsions significantly increased skin permeability in vitro, highlighting the potential for enhanced delivery of this drug through the skin.

Applying conditioner mid-treatment reduces hair damage during perms.

This study found that digital perm treatments using sodium thioglycolate lotion led to the most significant reduction in protein content and greater hair damage compared to other methods and lotions.

This study found that the PLEE method increased hair protein extraction efficiency threefold and that bleaching hair reduced the coverage of keratin and associated proteins, leading to poorer hair quality, though it did not affect the overall protein identification.

In this study, researchers found that barrier-enhancing formulations significantly reduced the penetration of proteins into hair follicles in porcine skin models, with effectiveness varying by formulation.

This study found that Transcutol P significantly enhanced the skin penetration of Finasteride in vitro, while cationic and anionic surfactants did not show such effects.

This study found that a nanoemulsion hair spray formula with 25% PEG 400 showed promising physicochemical stability, but further research is needed to assess its colloidal stability and efficacy in hair growth.

The study found that a polymer treatment changes the charge on hair surfaces, making bleached hair smoother and less porous.

This study found that using a hair-hardener improved hair thickness, amino acid content, surface condition, tensile strength, and wave efficiency without causing any allergic reactions in participants.

This study found that supercritical fluid extraction of germinated perilla seed significantly promoted hair follicle cell proliferation and gene expression related to hair growth, suggesting its potential as a natural treatment for hair loss.

Adjusting hair dryer settings improves drying efficiency and keeps hair healthy.

In this study, using an ex vivo porcine skin model, researchers found that a 4% nanoparticle concentration significantly enhanced the transport of fluorescein sodium into hair follicles compared to a 2% concentration, while higher concentrations did not further increase penetration depth.

This study analyzed the swelling behavior of human hair during permanent waving treatment, finding that both the microstructure and macrostructure of intermediate filaments swell simultaneously at the initial stage, and while partially destructed by reduction, they are considerably restored through oxidation.

This study found that clove oil and LPGSE pretreatment increased finasteride skin permeability, while extending urea pretreatment reduced its penetration.

This study found that finasteride could enhance the stemness of dermal papilla cells, suggesting potential benefits for hair regeneration approaches.

This study evaluated the learning curve for using the Hair Implanter Pen, finding it to be operator dependent.

Finasteride's effectiveness measured by observing hair cortex changes using a cheap and easy method.

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 found that the PQ-70 shampoo formulation demonstrated the highest Hair Humidity Resistance Factor, indicating superior anti-frizz performance compared to other tested shampoos.

This study found that photoepilation using intense pulsed light significantly reduced hair growth parameters, and phototrichograms may offer an objective method to evaluate its effectiveness.

This study found that porcine skin serves as a reliable model for studying drug absorption into human hair follicles, showing a strong correlation in follicular drug absorption between porcine and human skin.

This study found that applying 10% platelet-rich plasma significantly increased hair follicle density and reduced the time for hair formation in a mouse model compared to no PRP treatment.

This study showed that keratinase pretreatment effectively reduces the time for enzymatic unhairing in bovine hides by opening channels for faster penetration, which shortens the process by over 50% and enhances leather quality.

This article presents a practical tip to enhance the efficiency of follicular unit transplant hair restoration surgery, a procedure known for being effective yet time-consuming and laborious.

This study found that adding urea to a polyethyleneimine solution improved the coloring ability and color fastness of low-temperature hair dyeing with acid dye by enhancing dye penetration into the hair.
