Query: ALLERGIES? BEWARE!!

People who have allergies to scents and fragrances buy unscented products. One hour after using this "unscented" hair spray, the scent was still so strong that I had to wash and blow-dry my hair again to stop coughing and gagging. DO NOT BUY THIS PRODUCT IF YOU ALLERGIC TO FRAGRANCES !!!! I tried to email Idelle Labs, Ltd. who makes this product but they do not have a website and could not find an email address for them. very strange and frustrating!
