Triangle hair, also known as "A-line hair," describes a haircut with a triangular shape that frames the face. Think of the iconic hairstyle sported by Farrah Fawcett in the 1970s.
Triangle hair is a versatile and flattering hairstyle that flatters most face shapes. It creates an illusion of volume and movement, making it ideal for those with fine or thin hair. Historically, this haircut gained popularity in the 1960s with the rise of the mod subculture.
