I have chosen effect of hair dyes on our hair as the topic for investigatory project in biology. Plz give an idea as to how to proceed.
Dear student.
This is a creative activity meant to be done by the students based on their understanding and imagination. We recommend you to perform this activity on your own and revert to us for feedback.
You can take wool or threads of silk for hair, and the purpose of dye can be meet by using different fabrics color. Moreover you can use chemical such as copper sulfate, KMnO4 etc to show the effect of chemical, such as showing some allergic reactions (patches, redness, etc) on skin.
