I am related to a couple of stylists by marriage. There are a few tips that right off the bat won't make your hair perfect, but will help considerably. I personally have naturally curly hair that is very curly and very frizzy if I don't treat it right.
First, ditch the brush...at least when your hair is wet. Use a comb only. It will keep your hair from breaking because a brush sort of stretches your hair without you feeling it, allowing it to break.
Second, use a styling product. It doesn't have to have hold, and you can find products that don't even feel like you have them in your hair (i.e. hair is soft smooth and clean feeling, not crunchy or nasty feeling). I tried to get away without them for years (I'm into getting it done quick, no muss no fuss no make up even because it takes time I would rather spend sleeping). What I discovered was that when I use the products daily, my hair tangles less, flies around less, is just in general a lot easier to handle. Talk to a stylist about what you want to be able to do with your hair on a daily basis (or even what would help your current situation without making any major changes) and they can recomend some good stuff. I have also found some personal faves that I would be happy to recommend. I tend to like salon products better than the normal grocery store stuff...they just work better.
This last one, I was a little surprised to hear, but I was told that people should get their hair cut (or trimmed) every 6-8 weeks. I used to get it cut about once/year at best. Now, I don't go quite as often as was recommended to me, but I do go about every 3 months. The last time I went in when it had been over a year, my hair was so frizzy, even product wasn't helping and I didn't know what to do. They cut my hair dry that day, and just by cutting off the split ends, no product or anything, the frizz was totally gone by the end of the cut. I wasn't exactly a believer before I saw that, but since she told me hair grows about an inch/month and the reason it doesn't "grow faster" if you wait longer than about 8 weeks is that it just breaks off.
For what it's worth, I feel like I'm terrible at hair. I can never get my hair to do anything that any stylist ever does to it...related to me or not. I have, however learned that these 3 things make a world of difference. I don't blow dry my hair, but I was told as a teenager tht if you do blowdry your hair, that you should put product in it first so the product burns off with the heat so the heat doesn't ruin your hair. Hope this helps. Good luck.
