Glad you found some alternatives. If you ever see your dermatologist again, it would be interesting to know why he only suggested red nail polish was the problem.
I looked up the ingredients of Shellac and pasted them below:
Contains positive attributes of both nail polish & gel including solvents, monomers and polymers. Shellac does not include Formaldehyde, Toluene or DBP (Dibutyl Phthalate). A low level of photo-initiators are utilized in Shellac. Photo-initiators can lead to sensitivity with some clients.
So it appears that 2 of the common allergens in Nail polish, toluene and formaldehyde are not present so that may be why you tolerate this product better.
