Like others said, shaving won't make it grow in like a cis-male's hair. It's kind of like how when ladies shave their legs, the hair seems think and course when it's first growing back, but after a week or two of growing in, it gets soft again.
But there are some bio-females who do grow facial hair. Like, people with Polycystic Ovarian Syndrome might grow dark and course facial hair, either in certain areas on their face or all over. Some people naturally have slightly higher T levels which makes hair grow (I get some dark and course hairs which I need to shave, but only on my chin). It also seems to depend on one's ethnicity too, I know many ladies of Azorean ancestry who need to shave and wax all over their face, there's also
Balpreet Kaur who almost has an entire beard.
But unless you just happen to have PCOS, a hormonal imbalance, or genes that allow you to grow darker and longer hair, there's really no way to grow a beard without going on T or finding some alternative way to safely raise your T levels.
