So, this is a common question and the answer is not that simple. What we will do is when we meet the first time, we will talk about what it is you want and I can let you know what I think we will need.
Some appointments could be 30 to 45 minutes. Other appointments can be 15 to 20 minutes.
When I first started having my own “goatee/neck beard” removed, I went for 8 appointments in 8 weeks and all were about 15 to 20 minutes. (The key here is I was dedicated, lived close by and went once a week about every week.) I had been shaving and tweezing for years, but I had a nice patch on both sides of my chin, some random black whiskers on my neck and about 6 to 8 pretty dark and pretty regularly on my lip.
After the first few appointments, we got the majority and it felt so amazing. I felt so FREEEEEEEEEEEEEEEEEEEEEEEE and sexy and cute again. Week 4 to week 8, I would be there about 10 to 15 minutes.
Once we got to week 8 or 9, I started going once every 2 weeks for about 5 or 10 minutes while she hunted and pecked looking for whiskers on my lip, neck and goattee.
After about 12 or 14 weeks I would just text her when I found a random hair and I would TRY hard not to shave or pluck and go in for her to epilate it. Now, I am so free from all of that stuff. If I knew then what I know now about plucking, I would have never plucked. (Plucking stimulates growth! uggggg.)
