I would recommend getting an RO with more protein.
If you're interested in CJ there is:
Ingredients: Water, Cetearyl Alcohol, Behentrimonium Methosulfate, Hydrolyzed Keratin Protein, Helianthus Annuus (Sunflower) Seed Oil, Panthenol, Keratin Amino Acids, Hydrolyzed Yeast, Glyceryl Stearate, Simmondsia Chinensis (Jojoba) Seed Oil, Glycol Stearate, Prunus Armeniaca (Apricot) Kernel Oil, Cetyl Alcohol, PEG-100 Stearate, Tocopherol Acetate, Citric Acid, Disodium EDTA, Fragrance, Propylene Glycol, Diazolidinyl Urea, Iodopropynyl Butylcarbamate.
^This is more of a PT, but I hear it is moisturizing as well. My protein-lovin hair could probably easily nom this as an RO (obviously you'd need to leave it on for longer for full effects, but even 5 min in the shower while you shave etc helps)
There is the CJ Strengthening Conditioner:
Ingredients: Water, Cetearyl Alcohol, Behentrimonium Methosulfate, Vegetable Glycerin, Simmondsia Chinensis (Jojoba) Seed Oil, Olea Europaea (Olive) Fruit Oil, Panthenol, Cucurbita Pepo (Pumpkin Seed) Oil, Melissa Officinalis (Melissa) Leaf Extract, Urtica Dioica (Nettle) Leaf Extract, Piperita (Peppermint) Leaf Extract, Equisetum Arvense (Horsetail) Leaf Extract, Yucca Leaf Extract, Keratin Amino Acids, Polyquaternium-7, Lecithin, Fragrance, Phenoxyethanol, Caprylyl Glycol.
^Although I feel that the Keratin Amino Acids are way too far down on the list (and possibly too small) to really make this a difference....
The SS Caitlin's Conditioner is nice:
Ingredients: distilled water, behentrimonium methosulfate (and) cetearyl alcohol, babassu oil, vegetable glycerine, meadowfoam seed oil, stearyl alcohol, avocado oil, hydrolyzed oat protein, hydrolyzed jojoba protein, hydrolyzed silk, panthenol, glyceryl stearate, phenoxyethanol (and) caprylyl glycol (and) sorbic acid, aloe vera powder, essential oil blend, guar hydroxypropyltrimonium chloride, tocopherol, citric acid
If I were you I'd go for the Caitlin's or CJ Repair Me. I know CJ has a following but honestly I think the products are crazy expensive and I haven't been impressed by the few products I've tried. That's just my opinion.
There's also other much cheaper brands that have protein rich conditioners: Mill Creek (Keratin, Biotin), Nature's Gate Biotin (Others have protein as well), EO Keratin
