How many hairs are there on the human head? Posted on February 12th, But the funny thing is that, although all human hair serves the same basic functions, the number of hairs on our heads is unique to us. On average, humans have , hairs on their heads, but this number is not consistent across the board.

Your hair density the number of hairs on your head depends on many factors. Some of the main ones are race and hair color. Though there are no specific numbers for African hair, it has been proven that black people have fewer terminal hair follicles on their heads.

This lower number of individual hairs among black people is not necessarily a bad thing. The twists and turns in naturally curly hair give the illusion of higher density even though there are fewer individual strands. The hair color we are born with is another contributor to how many hairs we will have throughout our lives. Blondes have the most individual strands of any hair color, at about , hairs.

Brown hair is the next highest, with an average of about , strands of hair. People with black hair usually have about , hairs. Redheads have the least amount, at 90, Of course, these numbers are for healthy people with no medical issues that can cause hair thinning or baldness.

Weight for weight, it is not as strong as steel: more like aluminium, or reinforced glass fibres or Kevlar, which is used to make bulletproof vests. Hair follicles contain specialised cells called melanocytes which make melanin, the sun-protecting pigment that keeps hair lustrous and coloured. But these tend to decrease with time, according to Bruno Bernard, the head of hair biology research at Clichy in Paris, which explains the inexorable emergence of silver threads.

The melanin is still there, but not in enough quantities to keep hair from at least seeming grey.
