Removing Facial and Body Hair

Trimming the hair on the thighs

Q: Are you allowed to trim the hair on the top of your thighs and on the top part of your leg at the front if the hairs are big to stop you from having doubts when using the toilet or doing ghusl for e.g. having doubts whether the private organ has touched a hair after urinating because it is so close to each other?

Shaving the eyebrows

Q: When I was young I managed to shave both of my eyebrows by playing with a Gillette razor in the shower and it has never grown out normal like I had it from that time. I have really regretted it because some extra hair underneath the eyebrows is growing from my eyebrow to my eyes. So I do not look like how I used to normally. Now I remove the extra hair underneath to only have my original eyebrow left. Is this allowed for me? Because I don't change anything with my original eyebrow only the excessive hair that came after I ruined my eyebrow with shaving it all of by razor.
