19,000 More Hairs? Now THAT I Can Get Behind.

K18’s new FutureIQ™ Biomimetic Hair Longevity Serum makes a pretty impressive claim: up to 19,000 more hairs for more volume after 12 weeks.

But what does 19,000 hairs actually mean?

Let's put it into perspective.

The average scalp has roughly 100,000–150,000 hairs. So 19,000 hairs represents approximately 13–19% of your entire head of hair.

Still hard to visualize? See my visual below

Think ponytail.

Researchers have estimated that a ponytail can contain around 10,000 hairs. So, very roughly, we're talking about the equivalent of almost two ponytails worth of hair.

Now that's a number I can see.
