Some info I borrowed from another post...
Are You A Protien
Thank you, Supergirl. I copied this information as a reference because I want to be sure that I am careful with how much protien I use and what protien treatments are going to require special/more moisture.
Is it a protein treatment?
Motions CPR--YES
Motions Moisture Silk Protein--YES
ORS Olive Oil--NO
Kenra Intensive Emollient--NO
Cholesterol Conditioners--NO
Elucence Extended Moisture Repair--YES (though the name says moisture)
Aphogee Treatment for Damaged Hair--YES*
Aphogee 2 Minute Keratin Reconstructor--YES
Joico K-Pak--YES (not starred, but I'd consider this semi-hardcore)
ORS Mayo--NO
Dudley DRC--YES*
Ultra Sheen Duotex--YES*
Nexxus Keraphix--YES
Nexxus Emergencee--YES*
Dudley Cream Protein--YES
*=hardcore, though there are different levels of hardcority (like my word?) For example, a hardcore with keratin or animal protein is going to be stronger than one with collagen.
Notice that the one with the stars are all products that come in liquid form. They are so potent because they are straight protein (a few stabilizers and preservatives) with no creams and emollients to get in the way. The protein goes straight on your hair strand unobstructed by other ingredients.
