LASH LIFT Lash Lift treatment straightens your natural lashes at the roots, giving the effect of longer, lifted lashes. Your Lashes will stay that way for 4 to 6 weeks. The results are immediate and the added lash colour makes a mascara-like effect so you're always ready to go. LASH TINT LASH Tint lasts on the hair for about 2-3 weeks and does not cover the skin. This is a great option for eyebrows if you don't wear too much makeup and want a little bit of color without going overboard.
