Thin hair refers to hair that has a smaller diameter and less density compared to thicker hair types. Individuals with thin hair may notice that their strands are more fragile and prone to breakage. This condition can be influenced by genetics, hormonal changes, and environmental factors, leading to a less voluminous appearance. People with thin hair often seek products designed to add volume and thickness. Common solutions include volumizing shampoos, conditioners, and styling products. Additionally, certain hairstyles, such as layered cuts, can help create the illusion of fuller hair, making it appear more vibrant and healthy.
