1000 Days for Hair Growth Process?

Good evening, Dr Rassman,

Firstly, may I compliment you on a most professional and helpful site.

Secondly, I would like to know what time of the day is best to take Propecia. Also, I have read that the first stage in the hair growth process lasts for about 1000 days. So why does it take only 6 months for Propecia to start working?

Thank you.

I realize I just posted something similar to this earlier today, but I generally recommend that you take Propecia in the morning, for that is when the testosterone level is highest and the drug levels are highest in the first few hours of taking it. The half life is 4 hours, so by evening, the circulating levels of the drug will have substantially dropped. There are also ’tissue’ levels of the drug that last beyond the half life of the drug in the blood.

As for hair growth, there is no 1000 day rule. I believe that the drug kicks in a few months and may last for many, many years. It varies between patients. Please see Propecia and Hair Count.
