French pins, or hair pins, are long, thin, usually metal hair accessories used to secure and style hair. They are often made of brass or aluminum and have a pointed end that is inserted into the hair and a round or flat head on the other end that helps to keep the pin in place.
French pins are a versatile and useful hair accessory that can be used to create a variety of hairstyles, from simple buns to elegant updos. They are also a popular choice for securing hair extensions and wigs. French pins are relatively inexpensive and easy to use, making them a great option for both professional and home use.
