I just recently made a soap with an evergreen scent layered in. All the reviews say they love it, but it fades terribly after 30 days, and they wish they had used more. So, I used the max, and it's so strong it crosses my eyeballs every time I smell it, but if it does fade off, it'll be lovely. I'm nervously waiting the full 30 days.
I've had some fragrances that totally change after 4-5 weeks, for better and worse.
Unless you need to get rid of it, I would give it a full five weeks before waiving the white flag.
If it's still really awful by then, there are plenty of ways to repurpose it, you can grate it or chop it and add it to a new soap, Ciaglia & Confetti Soaps
but you'll still have to deal with the smell coming back.
I've also discovered https://ecosoapbank.org/about/sending-soap
I have soap bits, odd bars, ends, and full batches that have scents I just don't like that I send here. You pay to send it, but the payment is to help pay for education and processing. It's a really good mission.
