I can go curly on day 1, wavy day 2, and straight day 3. FL humidity did make straight not an option (air dry no product pic 4), but here in the dry mountain air I have my choice. I only use CurlySexyHair detangler on a regular basis. Sometimes an anti frizz serum, but not regularly. Same with hairspray on my bangs.
It would take me ages to blow dry my hair straight on a regular basis, while twisting a few strands near the front that don't curl as much as the back takes a minute.

Hi Angie --

Agree with lots of the comments upthread about wavy/curly hair being a bit unpredictable.

A few things from my perspective (wavy + coarse; transitioned to embracing waves several years ago):

-- W/C hair is a commitment; it doesn't do well with "I'll wear it straight today, curly tomorrow"

-- W/C hair is fragile; it doesn't take to being washed with even gentle shampoo daily (instead, "wash" with conditioner) and it needs so very much more conditioning/oils than I ever knew.

Straightening irons (which I rarely used) and coloring (which I do to cover grey) both create damage so those of us who do one or both need to try to counteract that.

-- W/C hair doesn't mean waiting around with wet hair forever; one can blow dry -- diffusers are one's friend -- without blowing straight

-- W/C hair usually needs product, and finding product takes experimentation, which I personally find a PITA. I use one and accept the consequences of potential "imperfection."

-- W/C hair not only benefits from an experienced-with-curlier-hair cutter, as mentioned, but may need to be cut dry to avoid wacko curl pattern issues

And to me there's no doubt living in a cold damp climate makes W/C hair more of a PITA!

My hair prefers hot and humid (so it dries fast with big waves) or drier (frizz-free smaller waves). Guess where I like to vacation? PNW in winter = 4 hours to dry naturally and potential to misbehave once I step into nature. But I have fabulous summer hair, ha!

I have very tough hair that can take a lot of abuse but since ditching the "wash + blow dry every day, pull hair straighter with brush technique" my hair is in super condition. That's worth the winter RATE thing to me.

[Besides, even if I straighten the second there's moisture in the air it frizzes.]

ETA to add photos. Know you all can't see but personally I prefer my features with natural (wavy) vs straightened hair.

My hair is very thick and has a good bit of wave, and I keep is short. The humidity is very high here, year round. Most important is a good cut. I do blow dry, but don't go for sleek and perfectly straight... not sustainable in the humidity! I am done in 10 minutes and it looks good all day. I do use a good bit of product.

I have very curly hair, much like Julia Roberts when she wears her hair truly natural. Like others have pointed out, curly hair is never the same two days in a row, which I find maddening.

I love curly hair on others, but not on me. It took at least 20 minutes to dry, couldn't be slept on without rewetting and redrying every day, and reacted oddly to different conditioners and waters (yes, even water. Hard/soft, well/municipal, etc).

I started doing Japanese relaxing 10 years ago and love it. My hair is sleek and straight, looks the same every day, and takes 10 minutes to style, start to finish. It doesn't care what conditioner I use or what the water's like. And I have a lovely, swishy ponytail as a bonus!

Straight hair is hands-down easier for me.
