How should I approach this girl

So I 18M go to this little plaza to get my hair done, And there’s this girl that works at this popular jewelry store in my city, And I go there not so often to get my hair done I found her attractive when I first seen her and I ended up finding her TikTok through the store’s TikTok. And I ended up going to the plaza to get my hair done again today , and I finally mustard up the balls to go talk her, I asked her what her name was and she asked me mine n stuff I did stutter. And then after I got my hair done I went to her and was gonna try and ask for her number but I got scared and she was too busy packing up the store I didn’t wanna like bother her. So I’m wondering if I should comment on her TikTok and act like I found her on my FYP, but I don’t want her to think I’m a stalker or should I just wait till I go back to get my hair done which is like once a month. ( Please help she’s so fine )
