Because we have a lot to do.

Let's look at a full morning routine with a shower. Shaving your legs and underarms can take 10-30 minutes. Add pubic hair and you're looking at at least another 5-15 minutes, and you really don't want to rush that.

Then there's washing the hair. If you have thick, long hair, it's going to take a while to do a thorough shampoo and conditioning. When my hair was long, it took me 20-30 minutes. If you have thin or short hair, then it won't be quite as long. If you use a leave-in conditioner, that'll add some time too, although you can multi-task while it sets.

Once you're done with all that and you've washed up, which should only take about 5 minutes, you've gotta get out and actually do something with your wet hair. If you're lucky, your hair can air/towel dry and still look decent. If you have frizzy hair or curly hair, you might need to use some hair products to tame it a bit. If you blow-dry it, that'll take 5-20 minutes. If you curl or flat-iron, that'll take another 10-30 minutes, or even longer if you have really thick or long hair.

Then there's skincare. Gotta moisturize, maybe exfoliate, and if you have acne, cleanse your face.

Then there's the eyebrows. Plucking fortunately takes only a few minutes. But if you're like me and you were blessed with dark upper lip hair, you also get to shave at least once a week.

Now onto makeup. The bare basics to cover up that "I just rolled out of bed and I have zits" look will take about 5-10 minutes. Elaborate makeup can take anywhere from 15 minutes to an hour, depending on how skilled you are, what you're doing, and how careful you are, because you don't want to rush and screw it up.

Then comes perfume, body spray, and/or deodorant, which won't take long. Then little hygiene things like brushing your teeth and flossing and whatnot.

Then you gotta pick an outfit if you haven't already planned one. When you have a lot of clothing, you have a lot of potential combinations, so it takes a bit of time to figure out what looks good and what doesn't.

To be fair, you don't have to do these things every single day. Most women don't wash their hair every day and don't have to shave every day, so that's nice. And not every woman curls/flatirons her hair or wears really elaborate makeup all the time, and not every woman has a complicated skincare routine. But there's still a lot to do.
