Hello from JustAnswer.
I am sorry that you are having so much problems with this rash?
Could you attach a picture of the rash, including the area on the forehead and the area on the scalp?
Thank you for the pictures.
From the appearance, this does most look like it is a primary inflammation of the skin, and your doctor must have also thought that this was the case on the later visit when he prescribed the Betacap.
Since treating it as an inflammatory condition has not helped, though, the next step that would be reasonable would be to treat it with an antifungal. There are some inflammatory conditions that occur in association with a fungal infection. The Daktacort that originally helped traniently is actually a combination product with one ingredient for inflammation and another for a fungus.
At this point, it would be reasonable to treat more aggressively with antufungal interventions. There are over the counter antifungal that can be applied to the forehead, such as clotrimazole. There also is an antifungal shampoo, called ketoconazole (brand name of Nizoral), that can be used to clean the hair and scalp, and can also be allowed to flow over the forehead when rinsing it out of the hair.
If i can provide any additional information, please let me know.
I think that changing to the ketoconazole shampoo is reasonable.
Yes, it is a cream. It is different because it is a dedicated antifungal cream, and it is as good as can be obtained over the counter.
There is no guarantee that it will work, but this is the reasonable next step to achieve that goal, yes.
