Washing hair?

I work out once a day in the afternoon. I shower in the morning before work and then when I get home from the gym. I use Aussie 3 Minute Miracle to condition and my hair, which is very fine, doesn't get dried out.

There are powders you can get for in between shampoos. I only wash my hair every second shower. On the off day, I just keep it in a ponytail.

I don't "wash" my hair after every workout. I tend to only shampoo my hair maybe twice a week, BUT I condition my hair everytime I shower. I have naturally curly (READ: DRY/FRIZZY) hair. I use Dove daily moisture conditioner each and everytime. It leaves my hair shiny and nourished.

I was thinking about this today!!

I normally wash it after each gym sesh but last night I spent a while drying and straightening it

So today I tied it in pigtails and tried to keep near the fans so it wouldn't go curly/get sweaty

I refuse to do all that again!!

I have a lot of super frizzy hair and I swim for some of my cardio. I find that if I shower twice I only rinse and condition the second time. Also, I'll apply a deep conditioning treatment twice a week before a workout or swim and it keeps things more manageable.

I don't workout twice a day, just once in the afternoons.
I shower in the morning and wash my hair, then shower in the evening without washing my hair.
What may be useful is a "cleansing" conditioner or using your conditioner as a shampoo.
I've used Hair One from Sally Beauty supply, which is modeled after Wen hair products, but when I run out and things are a bit tight, I just use my usual conditioner and scrub the heck out of my roots. Hair is happy and good to go. Saves your color, too.

A note on using Hair One, as much as my hair loves it, it tends to build up on the scalp so I'll switch off washing with shampoo and conditioner and using the Hair One. It really helps maintain my hair color and keeps the frizzies at bay.

These are common steps given for those of us with curly hair, because to keep nicely formed curls and avoid frizz, we have to pamper and moisturize. As long as you don't have naturally oily hair, they should help get yours back into shape after being washed so often.
First, switch to a gentle shampoo. Optimistically, you're going to look for one that is so gentle, it does not lather, meaning it is detergent free. You can find these at natural stores, or sometimes walmart carries an organic brand that falls under that catagory.You want to avoid harsh sulfates that dry your hair out (ammonium laureth sulfate, ammonium lauryl sulfate, sodium laureth sulfate, sodium lauryl sulfate, ect) . Second, read up on co-washing. It's basically using conditioner to wash your hair, scrub it nice and good and give it a good rinse. Slow down to only using shampoo every other day at the most. I use a product called nuetral protein filler whenever mine gets overly dry (and since I constantly dye it silly colors, this happens often), it makes a world of difference.
I workout daily, and find that as long as I rinse my hair out well, it's not gross without actually washing it.

I've learned to suck it up and have dirty hair sometimes. I'm a student and a coach so having super clean hair isn't always necessary...

I'd rather have a hot body over a hot head of hair. And it makes it super pretty when I go out and actually put a little effort.

Here's what I do and it works pretty well. My head is also pretty wet after a workout. After I cool down (or shower), I blow dry the wetness out of my hair and usually it's the side of your head (by your ears) and lower neck that may look greasy still. I sprinkle baby powder and sort of lightly rub it in...it absorbs the grease instantly!! Let me know if you try and it works for you.

I shower after every workout, just not wash my hair.

Bumble&Brown makes great dry shampoo for different hair colors. You can get it via Sephora.

I wet it and condition it when I shower after my workouts. I usually wash it just 3x a week. I have crazy hair which turns into a fuzzball if it's too dry. I try not to strip away the natural oils. If you do wash it though, use a gentle, natural shampoo.

I usually just rinse my hair out...if you wash every day, the natural oils on your scalp gets dried out, causing the frizzies. So I will sprinkle some cornstarch in my hair to soak up excess oils and brush out (do this if you have lighter hair, if you have dark hair, it will look gray).

For the moisturizing, I *LOVE* Fekkai Glossing Cream...just a tiny dab and buh-bye frizzies! (I double process my hair, so it can get extra dry)

Buy Dry Shampoo - it will be your new best friend. It is a quick fix for greasy hair. If you do continue to wash your hair that frequently, try a coconut oil leave in treatment once or twice a week. Also, leave in conditioners can work wonders. I use It's a Ten! leave in conditioner - its a miracle worker!

Use conditioner instead of shampooing everyday.

Welllll hair dryers tend to make your hair frizz so using just a towel will help keep the heat off your hair and cut down on the frizz.

Just wash your hair with the water then use soap and conditioner after the very last workout.
