If You Overuse These Beauty Products, It Could Actually Be Hazardous to Your Health

"These are great for rejuvenating and replenishing dry or damaged hair — my favorite is Bumble and Bumble Quenching Masque ($38). After you've clarified your hair, apply the masque and leave on for 10 minutes before rinsing out. You'll notice immediately how rehydrated and soft your strands feel. Just be cautious, as using a mask more than once a week can start to leave your hair flat, weighed down, and harder to style." — Derek Yuen
