Can see doctor to assess how serious first. For treatement:
- mild steroid cream, can treat ok fast but not good enough for relapse
- strong steroid cream, can have instant effect but cannot use too often.
Avoid: avoid foam shampoon or bath liquid soad that is too strong. Try to use those for dry skin - got paraffin to replenish water.
Non-medical cream can be applied. Most popular ones are centaphil.
After I avoid the foam shampoo and use centaphil, only need to use steroid cream sparingly. You can try too.
