Bleaching hair twice makes it very dry and weak.
research Impact of acid (”progressive brush”) and alkaline straightening on the hair fiber: Differential effects on the cuticle and cortex properties
Glyoxylic acid straighteners cause more protein loss but have similar hair strength effects as traditional alkaline straighteners.
research Chelators Depigment and Inorease Elasticity of Mink Skin
Certain chelators lighten mink skin and hair, increase skin elasticity, and disrupt hair growth without affecting fur quality.
research Photochemical alterations in human hair. I. Artificial irradiation and investigations of hair proteins
Melanin in black hair protects it from sun damage better than light-brown hair.
research Damage of hair fibers as evaluated by an electrical capacitance technique
research Thermoporometry measurements of human hair via differential scanning calorimetry
Bleaching hair increases pore size and changes pore structure.
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 The effect of treatments on the shear modulus of human hair measured by the single fiber torsion pendulum.
Different treatments change the strength and flexibility of human hair.
research Evaluation of Curl Durability for Artificial Hair Fibers
New resin B makes artificial hair fibers hold curls longer than traditional resin A.
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 Morphological analysis of polymers on hair fibers by SEM and AFM
Polyquaternium 7® builds up on hair, improving its look and feel, and AFM is good for measuring these changes.
research Long-term staining of live Merkel cells with FM dyes

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 Water distribution in human hair microstructure elucidated by spin contrast variation small-angle neutron scattering
The technique showed that human hair has two main parts, with 68% being rigid and the rest flexible, and water swelling affects its structure.
research Impact of ultraviolet radiation‐induced damage to hair fiber integrity: A multi‐technique physicochemical characterization of surface and cortex properties
UV radiation damages hair similar to bleaching, but double bleaching causes more severe protein degradation.
research Evaluation of Cysteic Acid in Bleached Hair Using Infrared Spectroscopy
Bleaching hair increases cysteic acid levels in a predictable way.
research Significant damage of the skin and hair following hair bleaching
Hair bleaching causes significant damage to hair and skin.
research Alopecia areata after severe allergic contact dermatitis to a permanent hair dye
Severe allergic reactions to hair dye can trigger hair loss and may be linked to multiple sclerosis.
research Impact of acid straightener's pH value in the hair fiber properties
Lower pH straighteners change hair more but weaken it.
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.
research Hair Coloration by Gene Regulation: Fact or Fiction?
Gene regulation could revolutionize hair color by altering pigmentation from within.
research Chemical Reactions Occurring in Curing Treatment for Permanent Hair Straightening Using Thioglycolic and Dithioglycolic Acids
Using both TGA and DTDG in hair straightening reduces hair damage compared to using TGA alone.
