No-poo+scalp issues advice??
I see some old posts but products come and go so I wanted advice that was more current.
I have shoulder-length fine hair with I think probably 2a-3b curls depending on treatment and season and I usually wash once or twice/week with a silicone-free conditioner (usually Native curl-care or Kristin Ess unscented), let it half-dry in a turbie-twist and add a bit of whipped shea butter on the ends and a bit at the top to smooth flyways, because it hydrates and makes my curls nice, and just scrunch and air-dry, i'm pretty lazy about it.
(I'm white but I have used a lot of products made for african-american hair just because mine is so dry.)
..but I appear to have triggered some sort of psoriasis on my scalp. I accidentally ordered a henna BLEND instead of my usual plain henna and figured "why not?" so I tried it and...something went horribly wrong, it was fine at the time but over the next couple weeks my usual mild itching and peeling got much, MUCH worse. can't see professional cuz medical bills are a thing, but my friend says it looks a lot like her own psoriasis. (could also be eczema, i do have a fair amount of allergies, but I sure thought I had most of it under control and the *rest* of my body seems to be fine.)
I've shifted to Hask Tea tree and rosemary conditioner, which thankfully is still an acceptable no-poo option, and I picked up some Mielle Strengthening Scalp & Hair Oil which is rosemary, mint, eucalyptus, tea tree, and a bunch of other cooling and soothing type things. but i'm not sure if it's helping, felt good at the time but now I'm back at claw-my-head-open levels of itch.
But i'm still hoping to take care of my curls??
honestly I am now questioning everything I ever knew about taking care of my head, so i'd love general advice about caring for scalp issues and curls at the same time. even basics! do i oil first and then co-wash? or other way 'round? should i be looking for a cg-appropriate shampoo and give up on the co-wash-only method I've done for years? in the shower do i scrub scalp with fingertips or silicone "brush" to remove flakes and then co-wash, or the other way 'round....? , or am i doing more harm than good with any scrubbing at all? am i going to end up cutting my hair short just so I can get to my scalp better with various soothing products?
(fwiw I tried posting in the curlyhair sub, and it wouldn't let me post? just kept marking it in red even after I added the required flair. so i hope you folks can help me.)
Thanks in advance!
