MISSOURI CITY, Texas -- For over 30 years, Christal Mercier ran Hair by Christal. When her sister Dena was diagnosed with cancer, Christal discovered a new mission in life. During cancer treatment, Dena lost all her hair. Christal prayed and came up with a design to restore her sister's hair. Christal also realized there were others going through the same battle who couldn't afford a full hair restoration, so she created the charity Hair Dreams by Christal. Since 2008, Christal has helped bring back smiles to the face of many free of charge.
