Last Sunday I got to my 9th month without haircuts. I've been using hair formula 37 since the begining of the year. It takes time to show its effect but IT WORKS WONDERS. I went to get a color retouch 1 1/2 weeks ago, and I'm already showing huge roots. My parent noticed them. Its growing really fast.
I was also very skeptical about it, but its working wonders even when I do things that diminish its effects, like sleeping too little and drinking too much soda. I strongly recomend it for anyone, there is a special offer right now and you can get a month of it bor 30 dollars. I really think that you can pass on the movies or any other expense and go for it. They give you your money back even 45 days after. Its worth trying, you'll know it after 40 days. A must do for all of us.
