If you have coarse hair, it will feel rough in texture and it may feel like you have a lot of it. Coarse hair can be straight, e.g. Asian hair, or curly or frizzy, naturally red hair. The diameter of coarse hair is the largest of all textures, which makes more prone to moisture evaporation and dry ends. Use Elasticizer or Elasticizer Extreme and Re-Moisturizing Shampoo and Re-Moisturizing Conditioner to tame frizz.
