MYHD 20 Volume Developer is an essential ingredient when colouring your hair. It activates the hair colour when the products are mixed together. This particular strength lifts or lightens hair by 2 levels. It also offers 100% grey hair coverage.
10 volume developer07.02.2019 ByChrista This product is listed as a 'no-lift' developer, however it does contain hydrogen peroxide at a 10 volume (3%) concentration. This will activate dye but not lighten hair. I used this product with a toner and it worked well. I would definitely purchase this MYHD developer for this purpose again, it is good value and doesn't smell bad.
