Totally a guess, but I'd think it would be 0.02 to 0.05 over 100m. It's not just weight or drag. I've noticed that it sometimes blows in their eyes when they're in the starting blocks. That's a possible distraction that could cost time.
FWIW, I've notice that Sha'Carri is slow out of the blocks. I wonder if some of that slowness is due to the wig and the awkwardness of placing the hands down with those long fingernails.
I would like to see a study that tests the effects of hair and baggy clothing in a wind tunnel.
I imagine that they'd be quite significant, considering that similar studies that test the effects of wind resistance on traditional cycling jerseys (non-tailored skin suits) and new form-fitting skin suits, have revealed a power saving between 6-10%.
Steering away from the race/sex baiting, the actual physics and physiology here are a bit more complicated. In cycling, you can see an fairly exact relationship between aero drag, power output, and speed. In running/sprinting there is aero drag, but the power output is dependent on things like footspeed and stride efficiency.
Also, and probably most important, a cycling time trial is ~60 min at basically steady state, where aero is everything. A 100m and basically all heptathalon events are short sprints, where >50% of the event is spent accelerating, and to a large degree, the best accelerator wins. Weight would be important here, and I have no idea how much wigs weigh, but to think it's greater than 1% the weight of the runner is pretty extreme.
Lastly, these athletes are trying to earn a living. Winning is important, but not as important as being marketable. If flashy hairstyles and jewelry make you more marketable it may actually be the wisest decision to forgo a percentage of pace in favor of notoriety.
Over the years there have been various speed suits in track and field. Go look at 1988 or freeman in 2000. Nobody seems to stick with them. Maybe it is peer pressure but I got to think it is more those lab measured improvements aren't showing up in races...

That's certainly possible. One skin suit might not be much better than other.
That's a separate question than whether a wig slows you down by a measurable amount of time (more than one hundredth of a second in track).
If you had to bet would you think that a long, flowing wig (about .25 to .33 of a pound on your head) does or does not make a hundredth of a second of difference? I would bet it would. I would love to see the data.
These wigs have a carbon fiber plate and extra bouncy tech fibers which confer a 4% advantage in competition. Abby is giving up precious tenths by going old school.
One day after winning her historic 5th 100m World title, Shelly-Ann Fraser-Pryce easily qualified for the 200m semifinals despite her hair getting in her fac...

When you are that fast, who cares, but who cares at all, especially not a bunch of hobby joggers? It is cool and fun to have some personality on the track!
I’d want a chin strap for that thing because I’d be too paranoid it would blow off in a nice headwind then boom laughing stock of the championships. Same with the eyelashes. The vanity is for real
I have natural hair, but not natural color. 62 and a full head of hair, don't like gray. What's the secret, i don't know. My brother who's 15 months older than me is bald.
SAFP wears what seems to be a wig or hair extensions. Style and all is understandable, but what’s the cost? Is it really less than one hundredths of a second? If not, why would she not optimize it to the edge?
