I feel your pain, I'm in the same boat. I really limit protein and I DT about once a week/every other week. I find I need to clarify often bc of the low porosity and hard water. If I don't clarify, my hair tends to get frizzier, dryer and poofy. Also won't clump.

For deep conditioning I like curl junkie curl rehab or GVP CB mixed with oil (whatever oil I have) as a pre-poo. I leave it on while I clean the house then wash and style as usual. Sealing was a huge fail for me but I can take in some oil and moisture this way. If my hair is clean (clarified) and moisturized I can also use less product. HTHs!
