I don't have scalp issues but I have one hair client that does and I saw flakes on my oldest daughter's scalp. I think it comes with long thick hair.
Anyway, on my daughter I "scrubbed" her dry areas with baking soda and then rinsed. I spritzed her and followed with a natural oil blend and that seemed to help.
On my client, on dry hair/scalp I oiled her scalp with Himani Navratna Plus Herbal Cool Oil and then layered on a deep treatment mix that I warmed beforehand. I put on cap and sat her under the dryer for a bit. I rinsed and then washed and detangled and it was all good. Not to dap myself up but her scalp looked BETTER than the first time she came to me.
The key ingredients on the Indian oil are sesame oil, menthol, amla, camphor, thyme, rosemary oil. Everyone who I use it on say they can feel it on their scalp and it helps with dryness and flakes. Be careful of what types of oils you use on your scalps. I've come to the conclusion that some oils help lube and clear the follicles and others plug em up which leads to over production of oil and what not and thus, itchies and flakes. I love wgo, but maybe it's too heavy. Try mixing in stimulating essential oils into a light carrier (grapeseed, peanut, safflower), pop on a baggy for a bit and see if that doesn't help speed up the soothing/healing process.
