Interesting Hair Facts You Probably Didn't Know

Your hair is the crown you never take off, and it’s often the first thing people notice about you. It symbolises your personality and the cut, colour, and style of your hair can speak volumes about you. Gorgeous hair gives us an instant confidence boost: when you’re having a gorgeous hair day you feel on top of the world, whereas a “bad hair day,” can leave you feeling down and cranky.

Because your hair is your daily confidence booster, it’s important to keep it looking fabulous by paying attention to its health and nourishment. From shampoos to conditioners, to serums and fashionable hairstyles, caring for your hair from root to tip is possibly the most important step in your daily beauty routine.

To help you appreciate your crowning glory even more, here are some interesting hair facts you probably didn’t know.


1. Hair is a storehouse of your personal information. You can detect everything that’s been into a person’s bloodstream by analysing a strand of hair; that includes medicines, drugs, alcohol, or vitamins, and minerals.

2. There are, on an average, 100,000 to 150,000 strands of hair on a human head.

3. A single strand of hair can support 100 grams of weight, which means that all hair strands taken together can support up to two tons of weight. This is equivalent to the weight of two elephants.

4. A new hair begins to grow as soon as it’s plucked from its follicle.

5. Hair growth is stimulated in warm weather and your hair will grow slightly faster than people living in cold weather areas.

6. Contrary to the popular belief, trimming of hair doesn’t promote hair growth.

7. We normally lose an average of 150 hairs a day.

8. On average a strand of hair will grow for six years before falling out.

9. The most common hair colour in the world is black and the rarest colour is red.

10. Hair’s main ingredient is keratin, a protein that is also found in our toenails and teeth, animal hooves, the beaks and feathers of birds, and the horns of rhino.

11. If you shaved all your hair off, it would take around seven years to regrow to shoulder length.

12. The five major elements that make up our hair are sulphur, hydrogen, nitrogen, oxygen and carbon, but there are 14 different elements found in a single hair strand. And here’s one we bet you didn’t know – there’s GOLD in your baby’s hair!


That’s right, gold! Babies under three months have more gold in their hair than older people. This comes from their mother’s breast milk but before you shear your baby’s locks and head to the bank you should probably consider how much gold that hair will contain. Unfortunately, gold is a trace element which means your new-born’s hair contains less than 0.1mm per meter.

So, now you know how important it is to take care of your crowning glory and remember that it doesn’t have to be golden to glisten. No matter what your hair type, colour, or style, TRESemmé has a range of shampoos and conditioners to give your hair the professional care it deserves.
