new to laser, need help please

hi, im new to permaent hair removal in general, though these past months ive gotten my first 2 laser hair removal sessions (on my “happy trail” line on my belly)

i am really not seeing any change so far, is this normal?
all i am seeing is persistent red dots, like shaving bumps almost, but a bit lgihter

i am only getting 4 sessions done because i jsut want to reduce the hair there
will this be enough?

also, after each procedure, does the hair that was sapped that sessioncome out immediatley, or just fall out eventually
if they are supposed to fall out immediatley or even after the next few days, im having problems

i would appreciate any help here, thank you!!!

Please read the FAQs asap. See link below this post.

Hair takes 3 weeks to shed. Whatever doesn’t shed wasn’t affected.

Are you male or female? Is the hair coarse? What is the name of the machine being used? How far apart are your treatments spaced? What settings are used? What is your skin type?

(as you can tell, we need much more information).
