Aim of the experiment :To test between Shampoo A and Shampoo B and to find out which shampoo is more effective in making my hair look shinier.

Procedure,  On day 1, I would apply Shampoo A on my dirty hair. Leave it on my hair for 5 minutes then wash it off with cold water.

Observation and Data Collection: After my hair is dry I would observe it under natural light and also take a picture of my hair so that I have record keeping of the shiny luster of the hair.

On day 2, I would repeat the same steps with Shampoo B.

Analysis: At the end of day two I would then compare the pictures of my hair to determine which shampoo between A and B was more effective in giving my hair a shiny luster.
