Scalp issues on medications

Hi, These have solved all my scalp issues, from various causes known and unknown over the years; so hoping to help even if in general.
But of course I cannot say whether it could be worth a try for you; or if your particular medication caused the scalp issue or it's a coincidence; or some specific cause might mean these would not help.

1. Reduce hair washing to once a week, and only with the healthy natural kind of shampoo -or just water. (Live away from the commercialised 'civilisation' for a bit and you may find that un-chlorinated natural water works great after a little while). If at first or after too many days the scalp got oily, I sprinkled baby talc on it and combed out. This doesn't happen any more.
   
   I believe that the more we pile cream, oil, goo onto the skin the skin gets used to it, thinking that oh I don't need to produce anything. Then at the sudden lack of it the skin pours out natural magic cleansing-moisturising oil to counter the sudden lack. Not asking anyone to believe this, it can be tried out -even better, verified such as by student research projects.
   
   
2. Cover hair well. I discovered this to be an amazing positive side effect of trying to combat hair strands on sensitive skin of the face, ears, neck. With the hair uncut, since Covid years,  combed to get rid of strands that detach from the scalp but still on the head as well as to massage scalp, and tied up,
   I have kept the head covered like this... 
   
   Fold a light-weight thin-fabric scarf as a triangle, tie the ends. Put the broad side at forehead, let the tied ends and the triangle corner fall towards to nape of the neck. Twist fabric to snug-fit from nape of the neck then up towards the tied ends several times, adjust till that loop comes round to fit snugly on the forehead.
   
   Adjust for any venting to suit the weather, wear hat against UV. Choose the fabric so it can stay snug and not too slippery. (Any hair band etc never work well and get lost.)
   I just bought a microfibre towel to cut up and experiment if that's anti-slip keeping hair strands from sensitive skin.
