Contact dermatitis and formaldehydes

I experience inflammation on my hands whenever I use a product containing formaldehyde/formaldehyde-releasing substances. These things are formaldehyde releasers (according to Wikipedia) and so far, they all bother me:
Quaternium-15
Imidazolidinyl urea (Germall 115)
Diazolidinyl urea (Germall II)
DMDM hydantoin (Glydant)
2-Bromo-2-nitropropane-1,3-diol (Bronopol) (formaldehyde release is not related to mechanism of action)
Tris(hydroxymethyl) nitromethane (Tris Nitro)
Hydroxymethylglycinate (Suttocide A)
[edit]
DMDM hydantoin and diazolidinyl urea seem to be the common ingredients in curly hair gels. I'm looking for a good strong gel. I've done flax seed gel, aloe vera, and Aubrey gels, but they don't hold my hair for longer than 6ish hours and the effect has completely worn off by the next day. Does anybody have suggestions or gels they are currently using that don't have these ingredients? I'm all for organic/natural, as long as it works! I guess I'm a combo 3a/3b girl.
**by the way, formaldehyde has been shown to cause cancer in rats, but the levels are deemed low enough in beauty products that it's "safe".
