Image of A telogen hair root at X40 original magnification. The sheath around the root is a follicular cast. Such casts can be seen in any disease affecting the hair follicles, at any stage of the hair cycle. Causes include dermatophytosis and folliculitis.

Image of A rough or dirty-looking hair with uneven edges may be suggestive of dermatophytosis. By increasing the magnification and using the X40 objective (total magnification X400), you should be able to see the fungal spores. This hair is infected with Microsporum canis. The rounded ectothrix spores can be seen around the hair shaft, especially in the close-up view.
