Curl Shaping Mousse , 5.7 Fl Oz (Pack of 1)

can this enhance natural wave without using a hot tool, just air dry? My wave is great while drying, then it vanishes. I have thin hair.

Does this company test on animals?

Which products should I purchase to protect my hair from daily curling iron and hold curls for more than one day?

does it make the hair crunchy?
