Why is my hair curly underneath but straight on top?

Here are the reasons behind the hair being straight on top & curly underneath:

1) Genetics – The double hair type can be due to genes. This gene is not entirely dominant for curly hair. It can remain dormant until activated, at which point it changes the shape of the hair follicle, changing the type of hair that grows from it.

2) Exposed Top Layer – The top layer is exposed to a lot of chemicals & the bottom layer receives less when you apply products. So these uneven applications of products & chemicals result in straight hair on the top & curly underneath. 

3) Hair being too long & Heavy – When hair grows longer & is heavy, it weighs down the top layer, making it appear straighter & the hair underneath remains curly. 

4) Too much sun exposure– If you expose your curly hair to too much sunlight, the top layer of your hair will become thin, resulting in the top layer being straight & curly underneath. 

5) Pillows – The top layer of hair come in contact with pillows, so the friction make the hair straighter & the hair underneath stay curly.
