Hey ladies!

This is my first post on this forum. I've type 2b hair, but they get kind of frizzy in the humid weather. I find it really hard to deal with it.
I have been thinking of getting a keratin treatment. There are two beauty salons who offer this treatment in my area. One of them offers keratin nano and the other one offers keratin Coppola. What do you think I should go for? I'm really confused.
I just need a temporary solution till my hair grows out. I used to have less curly/wavy hair when my hair was long.

Thanks in advance!
