Factors affecting the strength of hair
Introduction:

Hair fiber strength may be affected by many different variables such as age, sex, genetic composition, color, moisture and finally treatments performed on the hair using deferent chemicals in the form of shampoos and conditioners. 

You may propose other variables that may affect the hair strength.
 
 Project description:
In this project you will learn about the biology of hair and design an experiment in order to measure the strength of a hair fiber. You will then repeat the experiment with different hair samples and record the results. Finally compile the results of your experiments and draw a conclusion.
