I use a special lash shampoo that helps me take care of them after extensions. It is important to choose shampoos that not only cleanse your eyelashes, but also care for them, making them stronger and healthier. I usually buy
lash shampoo online as you can find different brands there and get ingredient information and reviews. But, of course, before using any products, you should consult with an eyelash extension specialist or cosmetologist to be sure of your choice. I hope this tip is helpful!
