GK Hart/Vikki Hart, Getty Images Cat litter is sufficiently radioactive that it can set off radiation alerts at international border checkpoints.

Deep folliculitis is usually more severe. Follicles are densest on your scalp, and they occur everywhere on your body except your palms, soles, lips and mucous membranes. Damaged follicles are at risk of infection. The most common causes of follicle damage are: Friction from shaving or tight clothing.
Dermatitis causes flaking, scales and sores on the scalp and is considered a result of excessive hair oil production known as sebum. Sebum is excreted by the sebaceous glands associated with all follicle pores. Sebum, in normal quantities, helps lubricate and nourish your hair. Excessive sebum can accumulate trapping dirt and lead to bacteria when acting upon yeast. Bacteria and oil causes stickiness and can produce sores, bumps and pimples.
