I've tried many different razors in my life but I've found that the cheap plastic single blade razors cause a whole lot less irritation than the triple blade and quatro blade razors. It seems counter intuitive to use the cheaper razors but it really has been working for me. So If you get in-grown hairs or razor burn I suggest using single blade razors and I use Aveeno shaving gel also. Thought I'd share it with the community.

Here is a link for the razors on walmart.
