Abstract
Embodiments of a method for demonstrating type and/or source of hair damage comprises extracting protein fragments from a hair sample with an aqueous solution, testing the resulting protein fragments with the MALDI-MS test, and then either comparing the results between a damaged sample and an undamaged sample or comparing the results between a damaged sample and a list of known marker protein fragments to identify the type and/or source of the damage.
Claims2
A method for demonstrating hair damage type or source, the method comprising:
- a) extracting the labile proteins using a suitable solvent from a hair sample;
- b) analyzing the protein fragments sample with MALDI-MS;
- resulting in protein fragment results;
- c) identifying the hair damage by comparing the protein fragments results to a list of marker protein fragments for particular damage.
