I've been thinking about getting a lash lift, as my eyelashes are very straight and don't look great even with using lash curlers and mascara. I've found an EVL lash lift and tint for £19 on Groupon, does this sound 'too cheap' and something I should be wary of? Also, does anyone know if EVL is just a cheaper version of LVL? Any advice/experiences would be greatly received
