If you have hair that's longer than an inch, you have probably used an insane amount of dry shampoo in your hair. Especially if you're in college and barely have time to eat, dry shampoo is your best friend. Here are the 7 times dry shampoo saved your life.

1. After a darty/tailgate

We all know the drill: go to the darty, get food, go home to sleep, wake up and go out again. After you wake up from that post-darty nap the last thing you want to do is wash your hair. You already straightened/curled it this morning so there's no reason to do it all over again. Just throw some dry shampoo in there and you're as good as new.

2. Finals week

You've been spending almost every waking moment in the library so washing your hair isn't even a thought in your mind. What should you do? Dry shampoo!

3. During your internship/adult job

If you have had an internship or any job that requires you to look nice when you're at work everyday, dry shampoo is always on you. You're not at that stage of your adulthood yet where you are willing to get up an hour early to wash your hair before going to your office job, so you just throw some dry shampoo in your hair and you look amazing, per usual. I seriously don't know how I would have survived my internship without it.

4. Morning classes

Morning classes never seem to get easier, no matter how many semesters of college you've endured. Who would ever wake up early before class just to wash their hair? Crazy people, that's who. Slap some dry shampoo in that mane!

5. Family gatherings

You want to look nice on holidays and regular family gatherings, but it's just your family. They've known you since forever so you don't really need to try that hard. Dry shampoo is the perfect mixture of looking nice without trying very hard. Sorry Grandma.

6. Before a date

Sorry boys, the cats out of the bag! If I'm hanging out with you and have been going to class or work that day, you can guarantee there's a boat load of dry shampoo hanging out in my hair.

7. Basically anytime I'm feeling lazy

There are many times when I don't feel like washing my hair (the rest of this article would say that's all the time, but trust me, I do actually wash my hair) and dry shampoo is my knight in shining armor.
