Thank you for asking your question. Which medication for "scalp pimples" were you prescribed?
If there is no destruction of the hair follicles, then this is most likely a folliculitis, or an infection of the hair follicles. This may be caused by Pitrosporum a yeast like organism or perhaps a fungus. I would first recommend an antifungal shampoo such as Lorpox. If you have not tried Selsun Blue yet, that would be worth trying before a prescription strength shampoo. The other cause of folliculitis is bacterial. This is best treated with Tetracycline 500 mg. twice a day. A second possibility is a much less common condition called Acne Necrotica Miliaris ( this is not relatd to typical teenage acne by the way. This is more severe in that it causes death of the hair follicles. It usually is also treated with Tetracycline, but the treatment is less effective.
If you are able to forward a picture I might be of better assistance.
Most likely a folliculitis due to a yeast like organism called Pityrosporum. I would recommend a prescription strength shampoo such as Loprox shampoo. A 10 day course of Sporonox in addition. If you have not tried Selsun Blue, that would be a good over the counter suggestion.
I would be happy to look at a picture.
If you would llike another opinion, please let me know.
