Does everyone seal just the ends or the entire strand? I suffer from ridiculously dry hair too. Not so bad that I have to carry conditioner around, and recently its been generally much better moisturised (thank you summer, and Qhemets), but I still think it could be better. I tend to seal just the ends with castor oil, because I feel if I sealed the entire length of my hair it would be one greasy mess. But is this something I should be doing?
Products in current rotation:

Terressentials Pure Earth Mud Wash; Elucence MBC (now really just for cowashing, leg shaving or emergencies); Curl Junkie: Repair Me, Deep Fix, Curl Rehab; AOHSR (retiring); Oyin Handmade: Honey Hemp, Hair Dew, J&B; Qhemet Biologics: BRBC (retiring- prefer Oyin HD), AOHC, OHHB; Jojoba Oil for scalp; Castor Oil or Shea butter to seal; Henna & Ayurvedic pastes when I can be bothered.

Still searching for the perfect stylers, but loving CJ CIAB over everything so far
