The Molecular Structure of Hair

Made by: Sabrina Sparks

The making/growing of hair

Hair is made of protein that originates in the hair follicle, and as the cells mature they fill up with another protein called keratin. When these cells lose their nucleus they die and travel up the hair follicle. Hair is made up of long chains of amino acids.


A hair grows 0.3 to 0.5mm per day - about 1 to 1.5cm a month and 12 to 15cm a year.

The average person's head has 100,000 to 150,000 hairs.

A single hair can support up to 100 grams in weight and a whole head of hair could support

up to 12 tons.

Hair is the second fastest growing tissue in the body.

Children lose an average of 90 hairs each day, which increases to 120 by old age.

Biblical Intergration

1 Corinthians 11:15 - But if a woman have long hair, it is a glory to her: for hair is given her for a covering.

Why I chose this molecule

I chose this molecule because I wanted to know what my hair was made up of. I was surprised to know that it was made up of several proteins and that a single strand of hair can be so strong.
