I'm sure many of our experienced colorist friends are already aware of how 100 volume
developer can be a salon "friend" or DANGER. I have never used undiluted 100 volume
developer to accelerate lift. I am aware that some colorists do this. However.......
Here's the situation: You are rinsing your carefully placed highlights or a globally
placed lightener at the sink. Everything looks great.... EXCEPT FOR ONE MISSED
PLACE, where the color is noticeably dark... (We missed a spot). OUCH!
The Cure: (My opinion only), Mix equal parts (a tiny amount will do) of 40 volume and
100 volume developer. This creates 70 volume developer. Mix this with your chosen
lightener. TELL the client that you are eliminating a missed spot which will take only MOMENTS. Towel dry that dark area very thoroughly... I then, squeeze the strand with
cotton, to assure that most all of the water is out of the strand. Now, with a Q Tip or a
very small brush, apply that formula ONLY to that one dark area. DO NOT LEAVE
THE CLIENT. Within 4 -5 minutes, the strand will be BLONDE. RINSE THOROUGHLY
with cool water.. light shampoo and condition. Problem Solved.
I recommend that you store this developer away from where you keep other developers.
I believe this product can be a life-saver... when diluted.. and in emergency situations
