When you start to lose your hair, either from a receding hairline or a growing bald patch, you probably start to look for some ways to slow or roll back the process. One of those is hair-building fibers. While they don’t actually help hair growth, these tiny fibers cling to the existing hair to fill out bald patches in a safe, chemical-free way. You’ll want to find fibers that match your current hair color, most importantly. Some you roll on and others you spray, it’s up to you whichever you prefer. You can also use hair-building fibers between getting your hair colored to touch up roots.
