Thanks for your suggestions. I am gonna try to figure out what it is that makes my hair so hard and dried out. My current hypothesis is that occasional PTs are good for me, regular use of protein rich products not so much.

Kathy I was gonna PM you about this! How much does porosity play into this?
3a/b, fine texture, low porosity, normal elasticity, mod-CG 7/11/11

Poo: KC Come Clean, SM Moisture Retention
CO: CJ Curl Rehab, CJ Argan & Olive Oil, Renpure Argan Oil, YTCucumbers, Sevi Pumpkin
Style: AIF, HESMU, Biolage gelee, KCCC
LOOB for second day hair

Like BS/ACV rinses, limit protein/humectants.
