research Review of the current understanding of the effect of ultraviolet and visible radiation on hair structure and options for photoprotection
UV radiation and visible light can damage hair, but there are ways to protect it.
research Investigation of aging effects in human hair using atomic force microscopy
Aging makes hair thinner and rougher, with less clear edges.
research Fiber-Safe Extraction of Red Mordant Dyes from Hair Fibers
Researchers developed a less damaging way to extract red dyes from wool using EDTA and DMF, preserving the fiber's strength for further analysis.
research Changes in intraepidermal nerve fiber and Langerhans cell densities in the plantar skin of rats after mercuric chloride exposure
Mercury exposure damages small nerve fibers in rats' skin.
research Interaction of polypeptides with hair in different reducing environments
Small KP peptide improves hair without reducing agents, while larger proteins need them for better results.
research Cosmeceuticals for Hair and Nails
Hair care products mainly work on the hair's surface and need professional guidance for use.
research Structure and Function of the Skin
The document concludes that the skin is a complex organ providing protection, sensation, and healing, with challenges in treating conditions like itchiness.
research Repair of sequelae from artificial fiber hair implants with hair‐bearing punch grafting
Hair-bearing punch grafting effectively repaired damage from artificial hair implants.
research Hair today, gone tomorrow: the degradation and conservation of archaeological hair fibers
Acidic sandy clay damages archaeological hair the most, while dry conditions preserve but make it brittle; silicone oil can help keep the hair flexible.
research Influence of anionic surfactants on coacervation with cationic guar gum for hair care applications
A balanced mix of cationic guar gum and anionic surfactants improves hair conditioning and protection.
research Fiber-Safe Extraction of Red Mordant Dyes from Hair Fibers
A new method extracts red dyes from wool without damaging it, although it slightly weakens the wool.
research Chemical modification of keratin fibers using 2‐iminothiorane hydrochloride
2-iminothiorane hydrochloride improves hair waving permanence without damage.
research Quantifying the effects of repeated dyeing: morphological, mechanical, and chemical changes in human hair fibers
Repeated hair dyeing significantly damages hair.
research Cellular Debris in the Grease of Wool Fibers
Cellular debris sticks to damaged wool fibers and affects wool cleanliness.
research Dilated human hair fiber after exposure to flames for 'split ends' cutting.
The Brazilian candle flame technique can damage hair by melting the cuticle and exposing the cortex.
research In vitro evaluation of changes of hair fibers subjected to oxidation-reductive straighteners associated with dyeing
Straightening and dyeing damage hair structure.
research Exploring the effects of wetting and free fatty acid deposition on an atomistic hair fiber surface model incorporating Keratin Associated Protein 5-1
Water and fatty acids affect hair's surface differently based on hair damage, and models can help understand hair-cosmetic interactions.
research Human pollution exposure correlates with accelerated ultrastructural degradation of hair fibers
Pollution exposure speeds up hair damage.
research Mechanical properties characterization of human hair fibers cortex region by multiparametric Atomic Force Microscopy mapping
The active ingredient improves the strength of damaged hair fibers.
research Analysis of Cysteine on the Surface of Hair Fibers with Spectrofluorescence
Cysteine formation on hair indicates damage, best detected at pH 4.5.
research Enzyme Treatment of Wool and Specialty Hair Fibers
Enzymes xylanase and pectinase clean wool and specialty hair fibers effectively without damage, offering an eco-friendly alternative to soap and hot water.
research Experimental Investigations on Hair Fibers as Diffusion Bridges and Opiates as Solutes in Solution
Hair can absorb and transfer opiates when soaked in water, with damaged hair absorbing more.
research Analysis of heterogeneous reaction between reducing agents and keratin fibers using Raman spectroscopy and microspectrophotometry
The study found that thioglycolic acid breaks down hair bonds more consistently than l-cysteine, which is less damaging to hair.
research Thermal Induced Changes in Cuticle and Cortex to Chemically Treated Hair
Heat worsens damage in chemically treated hair, especially bleached and straightened hair.
research Chronic urticaria versus dermatomyositis in a case of T- cell large granular lymphocytic leukemia
The muscle damage was caused by T-cell large granular lymphocytic leukemia, not dermatomyositis.
research Alterations in epidermal stem cells within the pilosebaceous unit in atrophic acne scars
Inflammatory acne damages skin stem cells and reduces their growth, leading to atrophic acne scars.
research Photodegradation of human hair: a microscopy study
UV radiation significantly damages hair, especially with humidity, making it more vulnerable to further damage.
research Water-Soluble Polymers in Hair Care
Alkaline hair relaxers damage hair, but cationic and non-ionic polymers can help reduce this damage.
research Scanning Electron Microscope Evaluation of Hair Dye Effects on the Cuticle Cells of Canine Hair
Hair dye can damage dog hair and cause health issues.
