Effect of Anti-Keratin Antibody on the Nature of Hair
January 1997
TLDR Anti-keratin antibody from cow milk makes damaged hair stronger and less likely to break.
The study investigated the effects of anti-keratin antibody from cow milk on hair fibers, confirming its binding to damaged hair. The antibody increased the elastic modulus and tensile strength of damaged hair and inhibited fracture generation in excessively brushed permed hair. The F(ab')2 fragment with two binding sites was effective in preventing hair damage, while the Fab fragment with a single binding site was not. This indicated that the anti-keratin antibody with two binding sites enhanced hair resistance to stretching and damage.
