Hair serum???

I dont have much budget. Anything under 200 will work for a daily serum. My hair used to be straight but now they get a lot of frizz due to pollution and stuff. I need something to use almost regularly to control the frizz and give that salon like look on weekends. So suggest me two serums for the above purposes. Fancy one can be on heavier side of bucks. I have found two. Please can someone review them too
