Main Article on Ingrown Hair Question: What do you think caused your ingrown hair(s)? Submit Your Comment Comment from: Butter, 45-54 Female (Patient) Published: December 21 Razor shaving caused my ingrown hairs. Comment from: YIGA, 35-44 Male (Patient) Published: July 25 Ingrown hairs are caused when you use too much pressure when shaving. A manual razor will pull and cut hair from a wrong angle. So as it tries to grow back, it gets blocked thus developing into ingrown hairs. I found a wet and dry electric shaver and when I tried it I didn't get any more ingrown hairs. Comment from: Miserable to look at, 45-54 Female (Caregiver) Published: June 15 They say that women usually don't get ingrown hairs on the face but I'm one of the women that do. I usually shave but I turned to plucking because it stayed gone longer. I enjoyed 3 months of not having to shave every day, but then all of a sudden I started getting these little tiny bumps being both sore and itchy and now has pus. Now I wish I had a mask I can wear for a month so that I can let the hair grow out long enough to shave again. REFERENCE: Jasterzbski, T.J. and R.A. Schwartz.
