The hydrogel with a 1:3 ratio of hydroxyethyl cellulose to hyaluronic acid is effective for delivering drugs through the skin to treat acne.
research Tunable Keratin Hydrogels for Controlled Erosion and Growth Factor Delivery
Keratin hydrogels can be customized for better tissue healing.
research Reinforcing chemically treated human hair with citric acid
Citric acid strengthens and improves damaged hair.
research Chemical bonds and hair behaviour—A review
Disulfide bonds are crucial for hair's strength, especially when wet.
research Scalp alopecias in richly pigmented patients
Hair care practices like using relaxers and tight braiding can lead to permanent hair loss in black women.
research Polyphenol–Inorganic Sulfate Complex-Enriched Straightening Shampoo for Reinforcing and Restoring Reduced Hair Integrity
The shampoo straightens hair while keeping it healthy and less damaged.
research Effects of permanent waving on changes of protein and physicomorphological properties in human head hair.
Repeated digital perming with sodium thioglycolate lotion significantly damages hair protein and structure.
research An ultrastuctural study of hair fiber damage and restoration following treatment with permanent hair dye
Permanent hair dye damages hair but it mostly recovers after 8 weeks; using certain hair care products can help repair it.
research 286 Assessment of hair surface roughness by objective analysis
Hair care products used for 4 weeks made hair smoother.
research Action of Nucleophilic Reagents on Hair Keratin
Nucleophilic reagents break down hair keratin, forming more lanthionine and lysinoalanine than in wool.
research Hair Lightening of Three Hemodialysis Patients Under Heptaminol
Heptaminol may cause hair lightening in hemodialysis patients.
research Effets indésirables des soins capillaires chez les utilisateurs
Hair care products can cause skin irritation and allergies.
research Not always “straight ahead” – A surprising cause of acute kidney injury
Hair straightening treatments can cause serious kidney damage, especially if you have skin issues.
research Preparation of Water Soluble Wool Keratin and Its Application for Human Hair
Water-soluble wool keratin can protect human hair from damage during treatments.
research Understanding the Effect on Hair Fibers of Coloring and Bleaching Formulations Using High Pressure Differential Scanning Calorimetry (HPDSC)
Hair coloring and bleaching can permanently break down hair protein and temporarily change its properties.
research Hydroxyl radical mediates cisplatin-induced apoptosis in human hair follicle dermal papilla cells and keratinocytes through Bcl-2-dependent mechanism
Hydroxyl radicals cause hair follicle cell death during chemotherapy by reducing Bcl-2 protein levels.
research Impact of oxidative hair coloring and bleaching on hair fiber properties
Bleaching damages hair the most, while dyes improve combability but still cause protein loss.
research Moisture as a Plasticity Switch in Blowouts: Glass-Transition Behavior, Viscoelastic Response, and Tension-Defined Shape
Moisture makes hair flexible for reshaping during blowouts.
research Permanent Hair Styles (“Perms”)
Perms can damage hair and scalp, so proper assessment and care are essential.
research Enhanced substantivity of hyaluronic acid on keratin substrates via polymer complexation
Polymer complexation makes hyaluronic acid stick to hair better, enhancing its moisturizing effects.
research Effects of silicone pretreatment on oxidative hair damage
Silicone pretreatment protects hair from damage and reduces color fading without interfering with bleaching or dyeing.
research Effect of equilibrium pH on the structure and properties of bleach‐damaged human hair fibers
Hair's structure and properties change with pH; acidic pH maintains strength and less swelling, while alkaline pH increases water content and swelling.
research The chlorine-hair interaction. III. Effect of combining chlorination with cosmetic treatments on hair properties
Cosmetic treatments after chlorination damage hair more than treatments before.
research Crosslinking structure of keratin. V. Number and type of crosslinks in microstructures of untreated and potassium cyanide treated human hair
Potassium cyanide treatment changes hair's disulfide bonds, making it more elastic.
research Direct Observation of Hair Components Involved in Formation of Permanent Waves
Microfibrils are key for permanent waves, and hydrolyzed keratin improves wave formation and hair condition.
research Vibrational Raman and IR data on brown hair subjected to bleaching
Bleaching hair changes its structure and weakens it, which is important for understanding hair damage and creating treatments.
research High Performance Conditioning Shampoo with Hyaluronic Acid and Sustainable Surfactants
The best shampoo formula used 1% high-weight hyaluronic acid, 10% acidic sophorolipid, and 1% salt for effective hair conditioning and cleansing without sulfates or silicones.
