There are a few reasons why your hair may be darker underneath. One reason is that the new growth coming in is typically darker than the hair that has been growing for a while and has been lightened by the sun. Another reason could be that you have built up a little bit of a melanin reserve from being out in the sun, which can make your hair appear darker.
Finally, it could simply be that the natural color of your hair is darker than what you see on the surface.
-Why is my hair darker underneath
If you have ever noticed that your hair is darker at the root than it is at the ends, you are not alone. In fact, this is a very common occurrence. There are a few reasons why this happens, and we will explore them all in this blog post.
One of the main reasons why your hair may be darker at the root is because of the natural oils that your scalp produces. These oils can build up over time and make your hair appear darker. Another reason for this phenomenon is that the hair at the root is newer growth, and thus has not been exposed to as much sunlight as the hair at the ends.
The hair at the ends is typically lighter in color because it has been bleached by the sun.
So, if you are wondering why your hair is darker at the root, it is most likely due to one of these two reasons.
Conclusion
If you have noticed that your hair is darker underneath, it could be due to a few different reasons. One reason could be that your hair is thicker at the bottom, which causes it to appear darker. Another reason could be that your hair follicles are darker at the bottom, which also makes your hair appear darker.
Lastly, it could be that you have more pigment in your hair at the bottom, which makes it appear darker.
