Chronic selenium toxicity may cause loss of hair and nails. Hair breaks at the level of the scalp with slight trauma, such as scratching, while the follicles remain intact. Hair can be lost from any body site. A rash on the scalp with severe itching has also been reported. Nails become brittle and are shed and the new nail is also dystrophic. Patches of skin may become red and swollen and then blistered and ulcerated.
