First of all, sorry for the delay in response.
Everyone’s skin is different, but two natural ingredients that have really stood out to me from my readings are:
In correct amounts, these two appear to have good outcomes for overall scalp health (hair growth, barrier function, hydration).
The Reversing Seborrheic Dermatitis and Hair Loss post goes over them in a bit more detail (with references).
Don’t have any experience with any of the products that contain these ingredients, so can’t really suggest anything.
However, working on a scalp formulation myself which uses both of these.
Hope that helps and you can find something that works for you.
If you have the time, please let me know how things unfold (or have already unfolded).
All the best.
