Will I regret it? Hair Stylists/ Hair Professionals!?

I want to go to the hair salon and get the hair gloss shine semi-treatment on me. I have some questions! Please answer!

1) Does it really work?

2) Does it make your hair NOTICABLY Shiny/silky/soft?

3)How long does it last?

4)Is it damaging to your hair?

5)I'm going to keep reapplying it when I go to trim my hair. Will my hair be severly damaged or anything? Will there be any hair breakage?

6) I have dark brown/black hair. Will it glisten and really shine?

7) Will it change my hair to nasty and thick?

8) How will the texture be after I finish this process?

Please answer all questions! Thank you!

P.S. I'm getting this professionally done!
