Use neitragena face cleanser for men. It’s its blue cream bottle. It has a cooling aloe effect that really does the trick. Use it in the shower in the morning and again at night to control the itching. It works for me.
Gotta shave every other day till you get used to it it won't itch after a few months unless you let it grow back too long as I just did lol. Just shaved them and feel fine. Also soak your razors in rubbing alcohol after use it kills bacteria which causes the blade to become dull. Can use a razor for months by doing this.
