There are all kinds of stories out there about what causes grey hair – some of them are true, some are just fairy tales. Let’s separate the facts from the fiction.
First, let’s set things straight – grey hair isn’t actually grey. In fact, grey hair is colorless. The melanin in certain cells within the hair shaft is what gives hair its distinct color. Over time, these cells produce less pigment, so the hair loses its color altogether.
The truth behind grey hair
Now, you’ve probably heard that tweezing or plucking out grey hair will make two grow in its place. This is one idea that’s definitely not rooted in science. Hairs grow one-by-one, so the single strand you pull will simply be replaced by another in the exact same spot.
You may also have heard grey hair is a sign of old age. But in reality, greys can show up at any age. In fact, on average, women begin going grey at a very young age of 34. Of course, one of the most popular stories out there is that stress can cause grey hair. And this one could actually be true. While there are conflicting opinions about it, high stress or shocking events have been known to cause grey hair.
