Exactly How to Cultivate Longer, Stronger Hair

This might hurt a little: Step away from the heat. "So much damage can be done mechanically from hot tools," cautions Bodt. "If it can burn through a tissue or your shirt, it can do the same thing to your hair."

Bodt has seen a lot of client success with switching to gentle tools like the Dyson Supersonic, $399. Also, she points back to washing your hair less as a good strategy for avoiding heat damage: "Obviously, if you're washing less, you're also not heat styling so much during the week, which allows the hair to grow and do its thing."
