They will drop it. All that matters is how much your account value is at the end of the day. If you got 25K, you're good.
So let's just say you started with 25K and made some bad trades and dropped to 24K you can still daytrade for the day unlimited and if you can make up that 1K difference by EOD, including AH, you won't be restricted.
Do know that the restrictions are pretty tough after you hit 25K and drop below it. The restrictions are you are pretty much limited to one daytrade only ever until you make the money back or deposit more money. If you violate that rule, you will will be limited to a cash only account because your margin will be taken away. This means you will only be able to trade with unsettled cash only. (3 days settlement for stocks, 1 day for options)
