Give brewed coffee a try, I've been using it for more than a year and my hairline is growing back albeit very slowly and I'm still far from having a good hairline.
Also keep in mind that I have thick hair and my hairline is bad because of stress.
You just have to apply the brewed coffee on your scalp where you want your hair to grow back. It's a very cheap treatment, especially if you're a coffee drinker.
