I use ALL(brand) FREE AND CLEAR. It works well and literally has no smell.

I use arm N hammer sensitive skin. They have two options with & without a fragrance that is safe for sensitive skin. I started the one with the "safe scent" about 6 months ago just because I do like when my clothes smell good, and so far I and my family are good with that brand. Hope it helps

If you have to give up fabric conditioner, you can use 1/2 cup distilled white vinegar instead. It works and your towels/clothes don't smell of vinegar

I use Arm & Hammer for sensitive skin with no fragrance. I do miss the fragrance on my clothes. It works good so far!
