Mysteries of Hydrolyzed Proteins
Updated: October 2017 I have been researching various proteins used in hair products. Claims that this or that protein are high or low molecular weight and therefore good for this or that fell short of an adequate explanation. And some people can use one type of protein, but not another. Some proteins are lauded as being good for certain hair concerns. Okay, why? The weight of the protein does play a role, and it makes sense if you compare proteins. I converted all weights to the unit “Daltons.” Smaller numbers are easier to deal with, reducing them to Kilodaltons gave some numbers which seemed a bit misleading.
