Yes, but maybe not "Magic Straight", per say.
As I am nearly a partner, in a (soon to be) newly opened Thai Salon, I feel some qualification in the field. 55555
Thai ladies do like the straight hair look, and at the very least, will have their hair "ironed", after shampoo and drying.
The procedure for long time flattening of curls and waves (don't know the name), or as my GF calls it..."to make the hair stlaight", involves the application of some special potion, or "cream", and takes around 3 to 4 hours, in all.
Also, "velly expensive". 55555
