I don't use the K-Pak because of the mineral oil. I do use three of the Nexxus protein treatments:

Nexxus Protein Treatments

For a "light" treatment, the Aloxxi Botanical is great and easy. My favorite is the Aloxxi Emergency. I use so little of the two Emergencee(y)s, that the 3.3 ounce Emergency lasted me over a year using it monthly. I think that is about $1 a use. Can't beat that. I don't have a lot of hair--so it might be a little more per treatment. They are so easy to use, smell fine--I gave up the homemade protein treatments.
