Usage of the hair grow products

I have tried many hair grow products, but very few has written exactly how should it use exactly. So it took much time until I have revealed the right way how to use them. It is important to wash your hair every day, otherwise even the DHT blocker products will not help too.
I am using now NISIM hair grow products, and I have to tell you that it was the most effective until now. Some little hair started to grow after 1-2 months. Otherwise it's good to know that the most effective chemicals are producing effects only after 2-3 months. The clinical experiments take at least one year. So be patient. Don't give up your attempts after one unsuccessful week.
