After 15 years with the same company, I was forced to look for a new job. I think that the tension and stress of job hunting and the interview processed caused my hair loss. I heard about Pro-Form Endure from a good friend of mine and decided to try it. I used the product for about 4 months but began to take effect after about a month and a half. Initially, the hair loss was stopped. 3 months later the hair began to grow. There were no side effects.
