DH and I both have allergies to perfumes and cats. I buy ALL dye free and perfumed free laundry detergent. It isn't "hypo,", it's "free". Hypo is low allergens, free is no allergens. I also use Seventh Generation dryer sheets, again 'free'. You can tear the sheets according to size of load. I can use a full sheet on 3-4 large loads but prefer to tear them down. My friends and relatives wear lots of perfume, therefore, I tend not to go to functions with a large and tight crowd. Got tired of coming home with itchy watery eyes and nasty headaches. They think I'm anti-social but I just can't stand the perfume.
