1本の髪の毛って英語でなんて言うの？

It is nearly impossible to count every hair, but it looks like you want to know how to identify one hair or many hairs. One of the easiest ways to do this is by referring to "one" hair as "A single" hair. "There was a single hair found in the car." "At the crime scene, the detectives could not find a single hair." When referring to more than one hair you could say "multiple" or "many" hairs. "The crime scene staff found multiple hairs, but none were the victims." "Why are there so many hairs on the sink?" So to count hair, you can use many, multiple, several, etc.

---> A strand of something such as hair, wire, or thread is a single thin piece of it. She tried to blow a gray strand of hair from her eyes.

▪ A strand of hair. A strand of hair is a single hair. ▪ A single hair A single hair is one piece of hair. Example sentences a. A detective found an unknown single white hair at the room b. There is 1 strand of hair. It would be an important clue in order to find the criminal

The plural term for hair remains hair. *He found a strand of hair.- We count hair by using "strand". So we can say two strands of hair. *They also found some fur on the couch.- Animals' hair is called fur. However we cannot say one fur,two fur. You can mention whether it was a lot or too little.

You could also have a' piece of hair' or a 'clump of hair.' However these two terms are not very precise. A 'piece of hair' could vary from being just one hair, to being a ball of hair - or even hair attached to a section of scalp. Because hair is both singular and plural, the meaning is sometimes unclear. However, a clump of hair would always be at least a few connected hairs. A strand of hair could refer to a number of hairs growing together or indeed, one single hair. It just means something which is 'thin.' "He reached towards her and brushed a strand of hair from her eyes." If there is one hair alone, it is just called 'a hair.' If there are a few, then they are 'hairs.' "The hairs on his chin were still noticeable after shaving."

The proper and correct term for one single hair is a 'strand' of hair. A bunch of hair is several strands. All of your hair is referred to as a 'head of hair'.

"strand of hair" is how we count a singular piece of hair.

When you are referring to a single piece of hair, especially from a person's head, there are two ways to talk about them. You can either say for example: "I found a hair." or "I found a strand of hair." Both of these correct. I hope that this helps! :)
