research iε-(γ-Glutamyl) lysine cross-linkage in citrulline-containing protein fractions from hair
Specific cross-linkages help make hair proteins stable and strong.
research Action of Thioglycolic Acid and L-Cysteine to Disulfide Cross-Links in Hair Fibers during Permanent Waving Treatment
Thioglycolic acid and L-cysteine change hair structure differently during perms, affecting hair strength and curling efficiency.
research Mechanism of Hair Curling via Laccase-Assisted Tyrosine Grafting Using BSA as a Model Protein
A gentler, less damaging method for curling hair using tyrosine works well initially but fades after washing.
research Chemical hair relaxer use and its potential effect on incidence of endometrial cancer in Black women.
Frequent use of chemical hair relaxers may increase endometrial cancer risk in Black women.
research Formaldehyde replacement with glyoxylic acid in semipermanent hair straightening: a new and multidisciplinary investigation
Glyoxylic acid is a safer alternative to formaldehyde for hair straightening and effectively changes hair structure.
research A Nationwide Outbreak of Alopecia Associated With the Use of a Hair-Relaxing Formulation
A hair-straightening product caused widespread hair loss and scalp injuries, mainly affecting African American women.
research Internal structure changes in bleached black human hair resulting from chemical treatments: A Raman spectroscopic investigation
Chemical treatments on bleached black hair change its internal structure by breaking and reforming bonds, and treatments with hydrolyzed eggwhite protein help repair it.
research Mechanism of Laccase-assisted Tyrosine Grafting on Keratin using BSA as a Model Protein
New hair perming method using tyrosine is gentler and can be done with a blow-dryer.
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 Mechanical characterization of curly hair: Influence of the use of nonconventional hair straightening treatments
Formaldehyde damages curly hair more than glyoxylic acid.
research Hair removal
Electrolysis and laser treatments offer more permanent hair removal, but have limitations.
research Permanent Hair Waving
Permanent hair waving uses chemicals to create long-lasting curls.
research Action of Nucleophilic Reagents on Hair Keratin
Nucleophilic reagents break down hair keratin, forming more lanthionine and lysinoalanine than in wool.
research Influence of Amino Acids on the Hair Structure Before and During Chemical Treatments
Amino acids like arginine and cysteine protect hair during chemical treatments, keeping it strong and less brittle.
research Analysis of structural change in keratin fibers resulting from chemical treatments using Raman spectroscopy
Chemical hair straightening changes hair proteins and mostly fixes broken bonds.
research Temporary Chemical Depilation
Chemical hair removal can cause skin irritation and other issues, but natural alternatives are being explored.
research A reciprocal lattice approach to assessing the luster of hair fibers, based on scattering by periodically deformed cylinders
A new method helps understand hair shine and various products improve hair care.
research Characterization of hair lipid and protein dynamics using EPR spectroscopy and treatment effects
Hair treatments and dehydration affect hair's lipid and protein behavior, influencing its flexibility and appearance.
research The Secrets of Beautiful Hair: Why is it Flexible and Elastic?
Beautiful hair is flexible and elastic due to its unique double-layered structure and can be enhanced with succinic acid treatment.
research Development of hair treatment as a natural alternative to chemical straightening
A natural hair treatment alternative to chemical straightening is being developed to reduce health risks.
research Let’s not split hairs
A new method strengthens hair without using harmful chemicals.
research Laser Lax for Donor Closure
Laser Lax is a new tool that measures scalp looseness accurately and comfortably.
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 Green chemistry method for hair strengthening and setting using visible light-mediated protein crosslinking
New eco-friendly method strengthens and sets hair using light and causes less damage.
