As much as I hate to admit it, I've never been one of those "I woke up like this" girls. I wake up looking like I was dragged through a bush, and I need like a zillion products to get myself ready to face the outside world.

My hair is the biggest morning challenge -- I'm an avid blow dryer-er, and I always either straighten or curl it, so years of styling have left me with really damaged ends and a bunch of broken strands at the top.

My work bestie's hair always looks insanely good (like seriously, it's annoying). I bribed her with a coffee to get her to tell me her hair secret, and she finally spilled -- Function of Beauty.

She told me that she had been using the customized shampoo and conditioner brand for about a year, but she recently started using their leave-in conditioner too. I'd tried the occasional leave-in treatment here and there, but my girl explained that Function of Beauty's nourishing leave-in treatment is completely customized to get your hair looking and feeling its best.

Whether it's the dead heat of summer or the bitter cold of winter, my hair is never as healthy as I want it to be -- so I decided it was time to try Function of Beauty's leave-in conditioner -- and I'm so glad I did.

After completing Function of Beauty's online quiz to give them information about what kind of hair I have, as well as some of my goals, I decided to try the perfect trio of customized shampoo, conditioner, and leave-in deep conditioning treatment.

A week later, my new hair care products arrived on my doorstep. The bottles were so cute and they even had my name on them! I noticed a huge difference even after the first wash.

I never realized what a difference a customized deep conditioning treatment could make for your hair. My hair felt stronger, softer and looked so healthy.

If you've tried custom hair care, here's some of your questions about Functions of Beauty's conditioning treatment answered!

What is the leave-in treatment?

Function of Beauty's leave-in treatment is an ultra-lightweight conditioning cream that you leave in your hair to help give an extra moisture boost.

Designed specifically for your hair type after you take a quick online quiz, this multitasking treatment smooths, hydrates, and your protects hair.

How do I know if I need it?

If you're anything like me, you've used an endless amount of hairspray and damaging hot irons, so a deep conditioning treatment is essential to restore your hair.

Function of Beauty has a fun online quiz that gives them info like how damaged your hair is, if it's thicker or a little on the thin side and if you want more volume or less frizz.

They use the quiz to determine what formula is right for you, and they have a special quiz for their leave-in treatment!

How do I use it?

You can use it as often as you feel your hair needs it. The leave-in treatment can be applied post-shower to either wet or dry hair depending on your styling preference. It can be used on wash days, in between washes, or for quick touch-ups on-the-go.

What's different about Function Of Beauty?

Function of Beauty is free of all those gross toxic ingredients you find in most store-bought shampoo and conditioners. That means no parabens, sulfates and it's vegan and cruelty-free, too!

Your locks are unique to you and have their own specific needs, so your hair care routine should reflect that. Using customized shampoo, conditioner and leave-in treatments from Function of Beauty will help your hair maintain its natural moisture and restore it to its optimal health.

I never realized how little generic shampoos were doing for my hair until I tried customized products. Function of Beauty's line of customized products has completely changed my hair game.

Plus, their convenient subscription means I never run out of my new-can't-live-without products. Goodbye brittle, dry hair, hello luscious locks!
