How to keep hair straight, not sure if this goes here... Options

[misskentucky]

I have naturally wavy hair. I only straighten it sometimes but when I do it only stays straight for a few hours or so. How can I make it stay straight without using a shit load of hairspray and making it hard?

[*This Confession*]

^I was going to suggest the same thing.

Most of the anti-frizz styling products out there work very well but not without the aid of good styling tools (meaning high heat) and the right brushes (soft but firm bristles). Yet even after all of that, if there is any humidity in the air, none of this will work to keep hair smooth...



Hmm I searched and found this

How to Straighten Hair with a Blow-dryer

Want to calm the frizzies or straighten your curls for a day? All you need is a round brush, a blow dryer, some hair products and about 30 minutes.


Steps:
1. To straighten hair, begin by shampooing, conditioning and towel-drying hair.

2. Apply a heat protectant product to your hair, paying special attention to the ends.

3. Place a quarter-size dollop of straightening balm in your palm. Rub your palms together to distribute the product over your hands, then massage it evenly through hair.

4. Comb through your hair with your fingers while gently blow-drying it on a low setting. This removes excess water.

5. Pull your hair into three sections, two at the sides and one at the back. Clip the two sides up.

6. Select a small portion of the hair from the unclipped section to straighten.

7. Using a thick, round brush and beginning at the roots, gently pull the brush through the hair to the ends while blow-drying it. Pull the hair away from your head, stretching and straightening it as you go.

8. First pull the brush through the underside of your hair so that you expose it directly to the heat of the dryer. Once that area is mostly dry, switch to the top of the hair.

9. Keep the tension consistent and evenly distribute heat over the section of hair you're working on. This ensures uniform hair texture and prevents overdrying of certain areas.

10. Once that portion of hair is straightened, continue selecting and blow-drying small portions until that section is dry and straight.

11. Repeat the process on the two other sections to straighten your entire head of hair.

Tips:
Always point the dryer down as you blow-dry hair; blowing hair upward can cause frizzies.

Tame flyaway hair with an antifrizz serum or pomade. Place a few drops in your hand, rub gently to distribute it, then apply it your hair according to the product instructions.

To achieve flat hair, finish styling with a ceramic flat-iron designed for hair after following the steps above. Choose the heat setting for your hair type, and allow flat-iron to warm before using. Select portions of hair, as per blow-drying directions, and slide heated flat-iron along hair, beginning close to the roots and going past the ends of hair, repeating if needed to fully flatten hair.
