I don't recommend going to a small shop with hundreds of dollars on the street. First, their equipment is not good. Second, their technical experience is not enough? Third, the pigment is not good (generally Korean semi-permanent products are imported, so the cost will not be very low, and the price is so low, so pigment must not be used).
I suggest you go to a professional beauty hospital downtown, which is more secure and the cost will be higher. Looking for a cost-effective one, go to a professional semi-permanent studio. Net adoption
