I have a question about skin care for men.  I have a problem with
ingrown hairs on certain parts of my face after I shave.  I have
followed shaving instructions and have shaved with the grain, I have
used a good gel and a clean blade and I shave after I shower.  Here is
my question:  I have used tweezers to remove hairs in the past, and I
worry that I have changed the follicles so the hairs don't grow
straight out.  Is this possible?  Do they repair themselves
eventually?

Have you ever tried an electric razor? You don't use shaving cream and
all that jazz. It might prevent the hairs from becoming ingrown as
opposed to more traditional methods.

Maybe the comments to these two question can help:

With an electric shaver, you can go against the grain, and cut every
last hair before it becomes long enough to grow back into the skin.

This is a problem that Afro-Caribbean / African American men suffer
from quite a bit - there are products designed to help, see sites such
as this:

I recommend using something like Aveeno shaving cream. Don't use
blades that shave too close (the original Sensor razors aren't bad). 
Tweezing shouldn't have any effect on the remaining follicles.
