I've been watching it again, too - they had like a 48-hour marathon a couple weeks ago haha. I watched the show when it was on originally and I was jealous of her hair back then - and I didn't even have curls at the time lol. Even more jealous seeing it now - it's just beautiful.
remember, with all advice or suggestions for your hair, YMMV!!
My hair:
2b wavy, medium texture, low porosity, med-high density. Protein finicky.
My routine:
Cleansing: DCNP, every 4-5 days (occasionally use CJ cleansers).
RO: CJSC, occasionally use JCDC
Gel: KCCC, CJCIAB for 2nd day hair (sometimes third)

Heat is my friend: warm water rinses, steam caps, and diffuse dry. I love CLU cloths and my Denman.
