I found that if I wasn't getting the red bumps the day that I shaved the problem was with the hair trying to grow back in and encountering a resistance and leading to irritation. I found that it helps if I exfoliate the area the day after I shave; just don't do it the same day as you shave. This helps to remove any dead skin cells that could be blocking the pores. I just use these exfoliating gloves that I picked up where the carry the loofahs and such in the stores. I just use a little bit of shower gel with the gloves in the shower, and afterwards just use some light lotion and it helps a lot.
