I have the same problem sometimes. My hair looks perfectly fine, and then there's like this super short strand frizzed up. There aren't really that many solutions that can actually fix this, but it's always suggested to either use hair gel to glue the strands to your head, apply a leave in conditioner to calm your hair (as if) or "wash and dry your hair a certain way".
This is the first thing that came out when I googled frizzy hair solutions and, I mean, isn't this "special" routine what we all do anyway. http://www.oprah.com/style/How-to-Deal-with-Thinning-Hair-Gray-Hair-Solutions-Frizzy-Hair/2
However, I hope someone will have a better answer or you'll find the solution yourself, so good luck.

The best shampoo that my friend used with frizzy hair was John Freeda that was really good. Her hair was so smooth and straight it was unbelievable you should really try it and see if works, give it time though!

Do u blow dry your hair after your hair after you take a shower? if u do then quit blow drying it and then it will become not frizzy and beautiful.

I use pro naturals moroccan argan oil, which reduces the frizz and keeps my hair soft and healthy. :) it's great. :P

I have crazy wavy hair that frizzs and I finally found my miracle product. Its by Agadir and its called "Spray Treatment". Find it on Amazon or at salons. I paid $38 in salon for it and found it for $14 on Amazon. My hair has been straight all week.

Try out Redken Smooth Lock leave in treatment.
Also, Glass 01 By Redken (serum). Put both these in before you blow dry or air dry your hair and it will help tame down the frizz. What are you using when flat ironing your hair? Are you trying a flat iron spray? I recommend AG Firewall. It has Argon Oil right in it, and it is an aerosol spray, which is much easier on your hair than a wet spray. The Argon oil helps strengthen your hair and makes it super smooth and soft. :)

ikr....all the time i spend already, n products too.... i shouldn't get even a single frizz...:P
