She starts by sectioning off her hair into three sections and covering her ears and hairline with lotion to make sure the dye doesn't get on her skin. Next, Ava mixes the Purple Ava-Lanche with developer and begins lathering the foamy formula on dry hair. While she waits for the product to work it's magic, the 21-year-old relaxes with Hally's under-eye patches and de-stress putty. Shampoo and condition as usual, then, "blow dry and voila!" the clip explains.
