Question:
I heard that women don't customarily say tachanun. So does that mean they should skip that in selichos. If so, exactly what parts should be skipped in selichos?
Answer:
You are correct in that women don't customarily say tachanun, so therefore they should skip the tachnun at the end of the selichos.
