my friends 20 year old doctor says hair but my 53 year old dad says bone. i just wana know!!!Are your nails made of hair or are they an extention of yoiur bone?
Fingernails and toenails are made of a tough protein called keratin.Are your nails made of hair or are they an extention of yoiur bone?
how can a dr be 20 years old? med school is more then 2-3 years lol nails are acurally made of skin cells from a growth plate at the base of your nail. During growth they die and the inside of the cells become filled with a hard protein called Keratin. keratin is one of the predominant proteins that make up hair. So, although fingernails are not made of 'stiff hair' they contain lots of keratin, just like strands of hair
Haha.Hair is made out of keratin and hair and nails are also made of keratin.So,You should be saying that hair is made of the same material as nails,not is nails made of hair.
Hope this helps :)
see i thought they were made of protein or something. but i would trust the doctor, no offense to ur dad
Neither are right. Its made of protein.
