I needed this to develop a part of my hair slower and then again for toner. It really did the job and I appreciate how big the bottle is. This will go a long way. I just wish I was able to also purchase the blondme 9 level lifting bleach. There was no drips or spills during the transport to me, so that made me happy for sure. This really makes for a smooth creamy texture and application. Would buy again for sure.
