I like this site for explaining how to do it and what the results mean. http://www.organiccolorsystems.com/t...-stretch-test/
Ignore their specific product recommendations, it's a site geared toward professional colorists and the company is, of course, pushing it's own products. The info is good, though, and the names of their products actually help me make a better connection between the test results and what it means lol.
Keratin and egg are proteins. I don't think Glycerin is.
remember, with all advice or suggestions for your hair, YMMV!!
2b wavy, medium texture, low porosity, med-high density. Protein finicky.
Cleansing: DCNP, every 4-5 days (occasionally use CJ cleansers).
RO: CJSC, occasionally use JCDC
LI: KCKT or CJSL
Gel: KCCC, CJCIAB for 2nd day hair (sometimes third)
Heat is my friend: warm water rinses, steam caps, and diffuse dry. I love CLU cloths and my Denman.
