* Hair is Light: Hair is primarily made of keratin, a protein. While long hair might seem heavy when you hold it, the actual weight is negligible compared to your overall body weight.
* Density: The density of hair is not high.
* Water Weight: Hair can hold water, which can temporarily add some weight when it's wet. However, this is temporary.
* Perception: Long hair might feel heavier than short hair because it pulls on your scalp or neck differently, but this is a sensation, not a significant change in weight.
In summary, any additional weight from long hair is minimal and would not make a noticeable difference to your overall body weight.
