1. Nail polish originated in China as early as 3000 BC.
The ingredients included beeswax, egg whites, gelatin, and vegetable dyes. In Ancient Egypt, nail polish was even used to signify class rankings: The lower class often wore n**e and light colors, while high society painted their nails red.

2. The invention of the car spurred the creation of the first modern-day nail polish.
Inspired by automobile paint, a completely colorless version was introduced in 1916. Revlon became the first established nail polish brand in 1932 when they released a cream color.

3. Essie currently sells 311 colors of nail polish, not including nail decals or specialty base and top coats.
You can even buy them in vending machines in airports and malls around the country.

4. Acrylic nails were introduced in 1978.
And they were invented by a dentist.

5. In 1934, a bottle of Cutex nail polish cost 35 cents.
It was only available in three shades of red.

6. The most expensive nail polish costs $250,000.
Nope, that's not a typo. The color, Black Diamond King, is made with 267 carats worth of black diamonds.

7. In 2012, nail polish sales reached $768 million.
This was a 32% increase over 2011, and was probably due to a rise in nail art mania.

8. Actress Rita Hayworth popularized red nail polish.
After the introduction of Technicolor, Rita's bold nails launched a polish movement. Much later, Uma Thurman would start a new trend of vamp-colored nails, thanks to her hit role in Pulp Fiction.

9. There are 13 types of nail polish finishes.
And they include: shimmer, micro-shimmer, micro-glitter, glitter, frost, lustre, crème, prismatic micro-glitter or shimmer, iridescent, opalescent, matte, duo-chrome, and translucent.

10. Opened bottles of nail polish only last about two years.
Unopened bottles can last indefinitely. But once you twist the cap off for the first time, certain ingredients evaporate, which changes the formula and consistency of your polish.

11. Some nail polishes have food in them.
Well, food extract that is. Nails Inc. recently launched a brand of nail polish with kale, which they claim will smooth and brighten nails. Londontown Lakur's formula includes garlic to strengthen and harden nails, while others have cucumber that allegedly prevents splitting.

12. You shouldn't throw your nail polish away.
The EPA considers nail polish a household hazardous waste so you should technically toss your unused bottles in a hazardous waste facility. (However, even the EPA says it's impossible to regulate every household, so there is an exemption to waste generated by normal household activities.)

13. Storing nail polish in the bathroom is a big no-no.
And contrary to some reports, you shouldn't put polish in the fridge either. The chill will cause the polish to crystalize, which breaks down the formula. Instead, keep polish in a dry, room temperature space without direct contact to sunlight.

14. Painting your nails is prohibited on airplanes.
One woman was even arrested for painting her nails on a flight. She did also use profane language and refuse to stop, but overall, most airlines frown upon nail lacquer in the sky.

15. Neon nail polish is technically illegal.
Or at least the FDA hasn't approved them yet. Certain colorants used to create neon and glow-in-the-dark polishes are not allowed, but that doesn't mean you won't find them on beauty shelves. Many companies like OPI use formulas with FDA-approved coloring, while your other favorite neon polishes are imported.

16. You can use nail polish to fix a run in your tights, thread a needle, and more.
Lacquer isn't strictly for your fingers and toes!

You can now add "pro nail artist" to your resume.

Your nails grow about 3 - 4 millimeters per month. That's a rate of approximately 0.1 millimeters a day.

Fingernails grow faster during summer. Why? There are a few different theories. One theory is that people absorb more nutrients during the summer; as they are more likely to drink a lot of water on a hot summer day. Another theory is that since sunlight exposure causes your body to make Vitamin D, the increase in Vitamin D results in your nails growing at a faster rate.

Toenails grow at roughly half the rate of fingernails. They typically grow around 1.6 millimeters a month.

There is a proper medical name for the habit of biting your fingernails: Onychophagia. It's estimated that 25-30% of children are in the habit of nail biting.

Your hair and nails are made up of the same protein. They are both made up of Keratin; however, your nails are much stronger than your hair due to the difference in the arrangement of Keratin molecules: which gives your nails more resilient properties.

Men’s fingernails grow faster than women’s. Men’s fingernails typically grow upwards of 3.5 millimeters per month.

Your nails do not breathe. Nails are not alive to begin with; so they don’t need to breathe. However, it's recommended that you do let your nails take polish breaks in order to avoid some of the harmful side effects of keeping nail polish/ acrylics on for too long.

Stress can affect the growth of your nails. Stress is one factor that will inhibit your nail growth. Don’t worry, however, your nails will grow again.

Fingernails need blood to survive. Blood flow is essential for nail health and growth; as this is how nails get their key nutrients. Your fingernails can actually temporarily stop growing when there is an injury preventing them from getting proper blood flow.

Fingernails cannot sweat. Your nail bed does not contain any sweat glands; so it's impossible for your fingernails to sweat.
