Does Hair Color Matter?

Does Hair Color Matter? | Science Fair Projects | STEM Projects
Have you ever wondered if the color of your hair affects how warm it keeps your head? In this experiment, we'll find out if darker hair is better at insulating than lighter hair.


The hypothesis is that darker shaded hair will insulate better than light shaded hair.

Method & Materials

You will measure 20, 40, and 60 grams of dark and light shaded hair and place them in separate paper bags. Then, you will place the bags in front of a heat lamp and record the temperatures at two minute intervals for ten minutes.
You will need hair from a barber shop, paper bags, a heat lamp, and thermometers.


The results showed that the bags containing the dark hair created the greatest temperatures, while the bags containing the light hair created the lowest temperatures. This supports the hypothesis that darker shaded hair insulates better than light shaded hair.

Why do this project?

This science project is interesting because it shows how something as simple as hair color can have an effect on how well it insulates.

Also Consider

Variations to consider include testing different shades of hair, testing different lengths of hair, or testing different types of hair (curly, straight, etc.).
