You can try an anti-frizz product. They come as gels, mousse, sprays, etc. Also you should buy a diffuser for your hairdryer. It's an attachment that goes on the end which helps direct the hot air into the roots. Also keep your hair dryer on the low heat setting.
I have very fine, extremely curly/frizzy hair. I found Silk Therapy and Chi by Farouk. I have never achieved such manageable curls or smoothness before. It's expensive, but worth every penny if you can swing it. It can be purchased at beauty salons or beauty supply houses, but my local HEB sells it a quite a bit les expensively althouth still not cheap.
My beutician used the Silk Therapy on me several years ago and I have been sold ever since. I think it would be good on any hair tends to be dry and frizzy. The entire line of Farouk products has been good for me with my naturally frizzy hair.
I can use these products and dry my hair on warn low setting, then put a little more product on my hands and run it through. This is the first time in my life my hair has ever been shiny!
I've figured it out! I still get a tiny bit frizzy but it's much, much less. My main problem was that I used too much shampoo...even though i have a LOT of hair all i really need is a little blob. Then I use MATRIX Biolage Conditioning Balm, rinse it out, get out of the shower, and put in some more Matrix, massage it through my hair, and leave it there.
Anyone else with hair that has a tendency toward dryness and frizz should try this!!
