It depends on what horns are you talking about. Rino horns are made of hair and elephants have tusks not horns. I hope this answered your question.


All horn is made mainly of keratin, the same protein that is found in hair and fingernails. Tusks are made of dentine, the same material that teeth are made of. Tusks are elongated, continuouslygrowing front teeth.
