Dermatology Questions? Ask an Online Dermatologist.
Hello from JustAnswer.
How can we be of assistance?
Is this causing any symptoms?
How long has this been present?
If this has been present for a short duration, this is most likely a folliculitis, particularly since it is extending into the scalp. Folliculitis is inflammation and infection of the follicles in the skin and can be related to either bacterial or fungal infections, but with the appearance, I would suspect a fungal infection.
It would be reasonable to try an over the counter ketoconazole shampoo and while shampooing the hair, to also apply it to the skin of the forehead.
If I can provide any additional information, please let me know.
Any ketoconazole shampoo would be fine. A common brand name is ***** ***** any would be fine.
This is also consistent with a folliculitis and the ketoconazole would be appropriate.
It is fairly common. It happens because a fungus or bacteria on the skin overgrows. The skin is never sterile and there are always a certain amount of fungi and bacterial present on the skin, but one of the germs grows excessively, it can get into and grow in the follicles.
Please let me know if I can provide any additional information.
