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 Bleached Hair as Standard Template to Insight the Performance of Commercial Hair Repair Products
K18® and Olaplex® both effectively repair bleached hair, improving its strength, smoothness, and overall health.
research Water-Soluble Polymers in Hair Care
Alkaline hair relaxers damage hair, but cationic and non-ionic polymers can help reduce this damage.
research Rapunzel! Rapunzel! How Strong Is Your Hair?
Hair can't be as strong as Rapunzel's because it's impractical to scale up due to defects.
research Low-dose oral minoxidil improves hair length and global hair density in short anagen syndrome
Low-dose minoxidil helps hair grow longer and thicker in people with short anagen syndrome.
research Tensile properties of twisted hair fibers
