How does Shampoo and Liquid Soap work differently?  

Liquid Soap is used for cleaning your body. 
Yes, you can use it as a shampoo every once in awhile but, if you
use it all the time, it will damage your hair and may cause hair loss. 
The alkali in soap can damage the proteins in your hair. 
In addition, soap reacts with metal ions (Ca2+ etc. ) and forms
a complex called “scum”, which is also not good for washing hair. 

How 2 in 1 Shampoo/Conditioner Differs from Using Both Shampoo and Conditioner. 

     There are 2 different ingredients for the 2 in 1 Shampoo/Conditioner: silicone and Dimethicone.  Dimethicone is what makes it condition your hair.  The suspending agent, Glycol Distearate, is what keeps the silicone from separating out of the formula.  The suspending agent is what keeps the silicone in the formula. When water is mixed in with the shampoo/conditioner, it cancels out the suspending agent which allows the Dimethicone to deeply condition your hair. However, it's different when using shampoo and conditioner separately. The shampoo is used to clean your hair and remove all the oils.  Conditioner treats and repairs damaged hair.   

Is tanning in the sun or using the tanning bed better for your skin?

 Many people believe that looking your best has a bunch to do with hygiene including tanning. Studies have proven that natural sunlight is better for your skin. This is true because tanning beds can cause radiation damage to the skin and cause skin cancer. Too much tanning in the tanning bed can sometimes result in death. In the sunlight, you are more likely to get a sunburn and slight skin damage (depending how long you stay out in the sun) rather than a result in death. It is important that if you are outside for too long that you use sunscreen to protect from the UV rays from the sun. If you want a safer way to tan faster in the sun, you can use tanning oil that has sunscreen in it. Tanning outside is also so much more cheaper.

Average Heights and Weights..

      As a teenager, height and weight varies as you grow.  Some kids the same age as you are taller and others are shorter.  That's completely normal for a teenager.  An average 16 year-old female is between 4'9" and 5'9" and weights between 90 and 180 pounds.  The average 16 year-old male is  from 5'1" to 6'2" and weights between 100-195 pounds.  So don't worry about how tall, short, heavy or light you might be.  Teenage size varies individually and no one is the same.
