Patience, I love your hair cut!
My hair is much thinner and finer, but very prone to flyaways and frizz. I have had to teach myself how to blow-dry it correctly. It is a learning process. Every time I'm at the hair salon, I ask my hairdresser to explain what she is doing, and let me try while she watches. It is worth it.
What I've learned:
1) Comb hair out with a big-tooth comb.
2) Allow to air dry until nearly dry. (do your make-up, get dressed, have some coffee).
3) Apply some mouse or some other product... experiment with this... everyone's hair is different. If you are flat-ironing, try something that will protect the hair from heat. I would tell you what I use, but since my hair is fine and thin, it is probably not what will work for you. Important thing is to add *some* sort of styling product. Not just for protection, but because it adds texture and "grippability" which will help with styling.
4) Use a large, round brush that has a metal shaft with holes in it and nylon bristles. Largest brush you can find.
5) Blow dry without the brush first, scrunching all around the roots, or flipping over as your stylist recommended. This is to dry the roots and add volume.
6) Using the large, round brush, dry from top to tip, a section at a time, holding the blow dryer DOWN the hair shaft - that is key! If you hold the blow dryer up the shaft, you end up with flyaways.
7) Dry it thoroughly. If you don't, it'll frizz.
8) Or use the flatiron at the end, to remove any excess moisture.
Excess moistuire = frizz.
9) lightly hair spray - spray the hair spray on your hands, then tap lightly down on any flyaways. Alternatively, try hand cream, with a very light touch. It works!!
