Review (2/5): Quality not worth the cost.
Was super to install myself, but I have to recrimp the rings daily. Upon washing, hair is SUPER dry (even with leave-in conditioner), and a good chunk of it super tight crinkles and does not flat iron out. Large amounts of the hair is falling out, am 4 days into installation and 2 washes.
Product is too pricey for the quality, will not purchase again!
