These Creepy Photos Give You a Zoomed-In Look at What Hair Damage Really Looks Like

If you've ever wondered what multiple hair color sessions can do to your hair, this is it. As you can probably tell from the images, the most significant damage comes from the midsection down (as opposed to at the root, which is where new hair grows in). "The [ends] show a complete absence of all protective cuticle scales, exposing the underlying cortex," said Dr. Kim Nickson, a senior scientist at the lab. Translation: that area of the hair strand is completely dead. The scale-like texture and fraying, she told us, are a direct result of chemical processing.

Not all hope is lost, however: Olaplex Hair Perfector No. 3 ($28) is the at-home version of the salon treatment that nearly every hair colorist swears by, and the formula works just as well to glue back the broken bonds that can result from repeated dye jobs. Use it once every 10 or so days to treat color-treated ends, and watch as magic happens.

For the most part, this is an example of relatively healthy hair. "A small amount of debris can be seen on the hair near the root, the lighter contrasting particles are salt crystals from perspiration, and the flakes are dead skin cells," Nickson said. There is a little breakage toward the bottom of the strand, as well as split ends, which come from intermittent heat damage.

Just like you'd slather on sunscreen before stepping out in the sun, you should be applying a good heat-protecting spray before bringing out the hot tools. Drybar's Hot Toddy Heat Protectant Mist ($26) is loaded with heat-activated proteins that help rebuild the hair fibers and UV protectors to shield it from damaging rays.

While this particular strand of hair comes from a head that's never been dyed, there's still relatively consistent breakage all along the cuticle. Nickson noted a large amount of debris (in other words: product overload) on the strand, with the top layer completely stripped toward the ends — a direct result of excess heat styling. "The tip is considerably smaller in diameter than the rest of the hair, and the fibers of the cortex have begun to split," she said.

We know, we know — the Dyson Supersonic Hair Dryer ($399) costs more than an Apple Watch, but we assure you, the technology behind it is just as genius. The device measures the temperature of the airflow 20 times per second to make sure it stays precisely at the heat setting you selected, and if it starts to get too hot, the dryer will self-adjust as needed to prevent your hair from getting fried.
