I want to ask, last night while I was scratching my head suddenly my thumb was pricked by the hair, and now it is getting deeper, will it be dangerous if the hair is left embedded in my finger?
First, make sure first that your finger was pierced by hair. It's almost impossible to get your finger pricked by soft hair, unless your hair has a wire-like consistency. Even if the hair pierced the finger, the hair will not be embedded. Stabbing and embedded are two different things. If indeed you believe there is hair embedded in your fingers, then there should be no problem. Hair will be absorbed by the tissue. If you find that swelling and pain arise, please consult a doctor. The doctor will make an incision to remove the hair.
That is my explanation. Regards.
