Last summer I used Le Kair's Cholesterol Plus for the entrie season (every single day for 1 hour a day) My hair was in moisture heaven with absolutely no dryness. It has a small amount of protein in it so I don't consider it a heay-duty protein conditioner.
Here are the ingredients: Deionized water, Lanette16, PEG 40, Castor Oil, Strearalkonium Chloride, Mineral Oil, Methyl Paraben, Propyl Paraben, Cholesterol, Jojoba Oil, Aloe, Vitamin E, Keratin Protein, Fragrance, FD&C Yellow No. 5, D&C Red No. 4
I use it after I wash and condition my hair (when I used it during the summer, I would rinse my hair with conditioner, and then use it as a deep conditioner for 1-2 hours). try it out. A 20oz. jar is only $3.00
