Propecia Thickens Hair

I have a question for you … on merck site it says hair mass can thicken up to two yrs… but I was told it can thicken up to three yrs… is that true??? and when is the best time to take propecia am or pm???please let me know your answer… thanks

Propecia is best taken in the morning. The thickening of the hair shaft will, almost certainly, vary with the patient. In some patients the best fullness may be obtained in one year, in others it could take two years, and in some possibly three or more years.
