Can we have a post sharing our favorite color formulas for rooting? It has been a bit of a learning curve for me working with the palest colors. I was getting a lot of violet tone even with my neutrals but I’ve added some gold and that helps. I tend to wet the hair, then add a level 10 1-2” under the zone 1, and then I add my root for a blurred effect. I find sandwiching them between large uncut foil work best so I can flip them over and saturate both sides easily. What are you best tips and tricks for coloring wefts? I recently used a 5vol lightener mixed with olaplex number 2 to lighten some wefts too. I want to know ALL the secrets!!!
