Two Fold Question - How Do You Handle Humidity? What Do You Do with Your Hair?

I put my hair up in an African Butterfly hair clip - I just LOVE these things!
It keeps it neat and off my neck (and doesn't get caught in the safety belt in the car or sat on) and when it's bound up frizz isn't a problem.

Hehehehheeh... welcome to the "south". I always shake my head a little when folks from other warm climate areas of the US talk about how hot it is where they are. They don't have the humidity, so they don't know what heat is really like.
Let me try to explain it: it's like walking around in a sauna.

So, is there a trick to keep yourself looking nice and your hair perfect? Yeah.. you stay inside 100% of the time in the air conditioner. You spend as little time as possible going from your house into your car, and you crank the a/c on in the car, on high, as soon as you start the engine (which is before you do anything else.. b/c you need to get that a/c pumping). Then after a few minutes, you adjust the a/c to recirculate (at first you need it on the outside vent, to help push the hot air out)...

Other than that... there isn't much you can do. Really. Lived here all my life. Went to visit Texas one summer and it was hot. But it was dry. It was glorious.
Here... stand back when you open the car door when you've been out running errands. The steam will scald you coming out of the open door if you aren't careful.

Well, I live in Florida. I have board-straight hair so frizzing is never a problem for me. However, I do always try to keep my style pretty simple...a complicated style with a lot of different hair products is simply not going to hold up in the heat/humidity here. I second the poster that commented on the air conditioner. Florida natives simply do not go out during the hottest part of the day. Air conditioning is your friend. Locals laugh at all the tourists down here that are miserable because they insist on spending the entire day outside.

I use a curling mousse. I can't fight the humidity. It is a loosing battle for my hair.

I like Herbal Essences "None of Your Frizz" shampoo and conditioner:

They also have an "Anit-Frizz" cream.

Usually I just use either the conditioner or the cream, but not both. If I use both, my hair tends to get greasy. So I often use a regular shampoo and conditioner with the anti fri cream or a regular shampoo and the "None of Your Frizz" conditioner with a simple staying spray line this one:

I let my bad hair naturally curl in the summer. Curl mouse and let it air dry. Simple and the humidity just makes it look curlier.

I have been living in the south for 4 years now, after living in the Northwest for my entire life. I love it, but the humidity does suck. (I still prefer it to snow though! Lol.)

I have long, thick, curly hair. Not really the best with humidity. Lol. I have tried product after product, and nothing works for me. (It's pretty unmanageable even in ideal weather...) I tend to wear it in braids, pony tails, and buns. It is also nice, because it keeps my hair off my neck which makes me feel cooler. Pinterest is great for giving me new ideas when I get sick of my go-to summer styles. :)

I'm not certain that I have a solution for YOU. I live in Houston, and the humidity takes us into three digits! Isn'tthisfun? got the process exactly right--spend as little tiem going between car and building. When I want to maintain a nice look, I leave rollers in my hair (or covered with scarf) until I am sealed up in a fully ACed vehicle. And that's going from house to attached garage! I take it down when I'm almost at my destination. If my husband is driving, he drops me off out front so I can run on inside.

This humidity is good for deep conditioning, though, and I take advantage of it. When I know that I'll be outside--like assisting with or attending a golf tournament--after shampooing my hair, I add lots of conditioner and sometimes certain natural oils. I typically wear a cap or hat, so the personal sauna on my head is good for my hair. When I'm ready to make any kind of fancy appearance, my hair looks and feels a-mazing! I just don't expect to have that every day. My everyday summertime hair is less fuss.

With the aid of certain products made for humidity, you'll figure out your rhythm for hair and skin care. You can do some deep conditioning on your skin, too! It will zap your energy to spend any real time out in it, but after you clean up, you'll feel how much better your hair and skin are! If you can, I say use the summertime to give your hair and skin a break from everyday wear and tear. People who live in it understand, so you wouldn't need to explain why your hair isn't bone straight.

The humidity here is awful! I have long curly hair during the summer I basically give up for a few months. I make sure it's conditioned and I get a trim and then wear it in buns or braids with some kind of cute hair band or wrap. I like to keep it off my shoulders if possible.

I purchased this based on a review I saw on a blog I follow (thesmallthings.com)... http://www.ulta.com/ulta/browse/productDetail.jsp?product...#
I haven't tried it yet, but it looks like it has good reviews.

I use this ... http://www.redken.com/products/haircare/smooth-lock/smoot...

I see the reviews aren't great, but I haven't had problems. I only use a little. I have incredibly wavy hair that's thick, thick, thick. I also use Paul Mitchell's smooth down shampoo and conditioner or Redken's smooth lock.

We live in a swamp, so in the summer it's braids, clips, pony tails, etc. DD's hair gets crazy. I also make sure it's conditioned because dry hair and humidity is worse.

I have found the key to this is having long enough hair to do stylish up dos, or short enough hair to keep it looking fresh. Keeping in mind that short really only works if you do not have wave or curl in your hair. I made the mistake of having a short-ish layered bob (think Lisa Rinna) with my naturally wavy hair and it was a disaster when it was humid. It is growing out, and nearly manageable,as we start to deal with humidity in NC. I use Paul Mitchell finishing spray and it works pretty well. I also use their mouse and or styling oil.

I am born and bred southern, and I have to be honest that I love the heat plus humidity. Transplants here think I'm nuts, but there is just something that's nostalgic about humidity for me. Such as watching fireworks on the 4th of July. It wouldn't be the same without dripping sweat in the heat and humidity. :)
I wear a lot of dresses and skirts in the summer in light fabrics. Also, if you have trouble with sweating through your shirts or the crinkle, I would suggest layering a thin tank top underneath your shirts. You might think it will make you hotter, but it really doesn't. What it does provide is that extra layer of sweat protection, and keeps your outer tops looking fresher. A lot of deodorants will stain the pits of your clothes, and a tank top or cotton camisole does protect your clothes from sweat stains. Plus they are inexpensive to replace (which I do at least once a year).
As for hair- I typically use Paul Mitchell styling lotion for my hair. It's light and gives good shine and control. I also have great success with Finesse hair spray. It's light, has good hold, and doesn't get goopy with the dampness. The wrong kind of spray also will make your hair a mess since humidity can make your hair flat/heavy and then it becomes a helmet as it dries out. Hope this helps!
