                                According to dermatologists, a person who does not have naturally coarse hair may develop it due to certain factors, and nutrient deficiencies are a major contributor. Several deficiencies can impact hair texture, causing it to become dry, brittle, and coarse over time. The root cause often lies in inadequate levels of key vitamins, minerals, or proteins necessary for healthy hair follicle function.
