Coarse hair strands are characterized by a larger diameter compared to fine or medium hair. This larger diameter means that the individual hair strands are thicker and can often feel more substantial to the touch. Coarse hair also tends to have a different texture and can be more resilient to some styling treatments. Understanding the diameter and characteristics of coarse hair is crucial for cosmetologists when selecting appropriate products and techniques for hair care and styling. By recognizing that coarse hair has a large diameter, professionals can better cater to the specific needs of clients with this hair type, ensuring optimal results in their services.
