I have a question about how to take care of my hair after laser hair removal!

I'm about to have an underarm laser hair removal course.
I've heard that post-laser hair removal care is the most important thing to maximize the effectiveness of the procedure and minimize side effects.
Especially since this is my first time trying this area, I would like to know in advance about how to care for my hair after laser hair removal.

Are there any special precautions I should take during the post-laser hair removal care period?

In addition to cold compresses, would it be effective to use soothing creams or gels to effectively reduce redness and heat?
Should I still apply sunscreen to my underarms to prevent any potential pigmentation, even though my armpits are exposed to minimal sunlight?

If so, what type of blocker do you recommend?

How many days after the procedure should I avoid saunas, steam rooms, swimming pools, and strenuous exercise?
If I feel any abnormalities such as dryness or itchiness after the procedure, what moisturizer is recommended, and when can I start exfoliating?
I heard that while the hair grows during the course, you should avoid tweezing or waxing in addition to shaving. Will this stop it?
How many days before the next procedure is the best post-laser hair removal care?
I would like to ask an expert for advice on post-laser hair removal care!
