If your scalp is just dry giving it more moisture may help. Are you CG? Do you cowash? What are you using now?
The SM black soap line contains Salicylic acid (like for acne), I'm not sure what black soap is/does, it will probably help with some scalp issues (depending on there cause) but it could also dry you out more.
Using a cowash with lots of emollients, some protein and few to no oils/butters may help eleviate the dryness if that's all it is. However if your scalp issues are a symptom of something else it will only be a temporary fix until the underlying cause is treated.
