Here's Exactly What Happens When You Flat-Iron Your Dyed Hair

Don't watch this if you religiously straighten your hair.

A recent Instagram video from hair stylist Guy Tang will make you put the flat iron down for good -- especially if you have dyed hair. Whenever you heat style your strands, your straightener/curling iron/blow dryer fades the color instantly. Yes, instantly. If you don't believe me, the proof is right here:

Yikes. You already knew on a subconscious level that regularly heat styling your hair was bad, but watching the damage happen in literally SECONDS makes it even harder to lie to yourself the next time you pick up your hair straightener. So if you want healthy hair and vibrant color, keep the heat to a minimum. No exceptions.
