Transcript of Does Nail Polish Slow the Growth of Nails?

Adding protein to the diet is essential to build calcium and encourage healthy nails. It can be found in various types of oily fish, cold-pressed oils, red meat, chicken breast, nuts and sunflower seeds
Nail polish is basically paint that sticks to the nails for cosmetic purposes. They come in many different colors and finishes. The possibilities of decoration are endless. New trends show an increased amount of production of matte nail polishes. Matte nail polishes have a dull and non-coated finish. The traditional nail polish usually looks shiny and glossy.
What are Nails Made of ?
The fingernails are produced by living skin cells in the finger. They are made of mostly keratin, a hardened protein (also in skin and hair)
Does Nail Polish Slow the Growth of Nails?

Nail Polish- Good or Bad for Nails
In this experiment, we will find out whether nail polish slows down the growth of nails. We will also be comparing the growth rate of bare nails with it.
What are the Ingredients in Most Nail Polishes?
We chose to use OPI nail polish. Since 2006, they have changed their entire line of nail polishes. They eliminated DBP (Dibutyl Phthalate), Toluene. Formaldehyde has never been an ingredient in their nail polish.





Ingredients in the OPI nail polish include...
ethyl acetate-30%
butyl acetate-25%
propyl acetate-15%
tosylamide/formaldhyde resin-10%
isopropyl alcohol-10%
trimethyl pentanyl diisobutyrate-3%
triphenyl phosphate-3%
ethyl tosylamide-2%
stearalkonium bentonite-1%
(The rest are less than one percent of the nail polish bottle)

What Foods Effect Your Nail Growth?
Day 1: Cut, file and measure our test subjects nails and paint their nails.

*leave their nail polish on for one week.*

Day 7: remeasure nails, add another coat if needed.

*leave on for another week.*

Day 14: Measure long nails, take off nail polish, cut nails and remeasure nails .( nails are cut back to the same length as Day 1)

*leave their nails with out Polish for one week.*

Day 21: Measure unpainted nails.

*leave unpainted for another week*

Day 28: Measure nails again without polish. (final day)

In the end we will analyze our results and see if our hypothesis is correct or not.
