It having a 22 hour half life does not mean applying more often won't improve results. All it means is the half life is 22 hours.
There was an old post about someone who did not get any results over 5 years applying twice a day. When he started applying 4x/day he got great results.
"Man,its been so long since Ive posted here. I think my last entry was in late 2004 !! Yep,that long ago. I met so many great people here. The reason ive been gone so long is that once I FINALLY found a solution for my hairloss,my life became super active again and I never looked back. I didnd have time to come to hairsite any more.I was no longer depressed. I didnt think it was fair to everyone here who is suffering the way I did If I didnt let you know what finally changed my life. What I did MAY work for you. I feel that I owed it to all of you because if you were anything like me,you were probably told,and you probably red that Rogaine is basically a joke.You have all probably read that Rogaine either works or it doesnt so dont waste your time ever putting on more than the recommended one "bulb" full from your basic sized bottle. Im here to let you know that I too thought Rogaine was a waste of time and full of S$%^. I was wrong,.WHY? Because IF putting on more,or applying more than twice a day isnt a good idea,then why was Rogaine originally sold as 2% but then extra strength 5% Rogaine became the standard? Ill tell you why, because the more you use,the more hair you regain. I used Rogaine at regular dosage for 5 lousy years and it NEVER did a thing. But then,a funny thing happened.... My local Costco started offering 5% Rogaine at insanely cheap,bulk prices so I decided to use it between 4 or 5 times per day. Yeah,yeah I know,"thats a bit crazy isnt it?" Well,No it isnt, Because?... I grew back 90 % of my hair and totally halted any further progression. Im almost 37 years old but now,am always approached by woman because of my confidence and never thought to be a day over 27 0r 28. All in all,my life totally changed and thats why I decided to come back. To Let all of you know that there MAY be hope for you. I didnt want to keep my secret forever,not if it could be used to help my fellow sufferers. I once was JUST like you,reading here at hairsite,feeling crushed. Im telling you,PLEASE take a chance that maybe,just maybe im not full of s#$% and maybe using Rogaine more aggressively will change your life. I know theres a chance that it wont work for you,and im deeply sorry for that but do you really want to live the rest of your life,losing more and more hair as you wonder "maybe I should have given it a shot" "maybe that guy was serious". Take care and Happy Holidays. Warmest regards, J.Z. aka Justin2Rue"
