 Hey guys, Brian here from freesaloneducation.com with step 3 of your 14 steps to becoming a better hair colorist. Today I wanted to just to help give you guys a little bit better understanding of what developers are and what their intended purpose actually is. I feel like that's something that, again, we are in the business so long and we do so much hair color that you get used to doing what you're used to doing and you kind of forget what tools you really have at your disposal. So to bring it all the way back to get just a little bit better of an understanding, developers are basically just a blend of hydrogen peroxide and water. And what that is, hydrogen peroxide is going to be the energy that's going to activate the dye molecules in whatever dye or hair color you're using. Your volume is chosen for the ability to control the lift that you're looking to achieve. That's why you have a variety ranging anywhere from 5, 10, 20, 30, 40 volume. And the way that it's going to work is the oxygen from the hydrogen peroxide in the developer is going to mix with the ammonia in the hair color and that's going to help lift the natural level of the hair while depositing the artificial color into the hair at the same time. The way that it's going to work is we've all seen at some point now what a hair strand looks like up close and you've seen the cuticle layer, how it lays almost like scales or shingles on the outer layer of the hair and the developer that you've chosen is going to help lift that cuticle layer up allowing the dye molecules into the hair and that's what's going to give you your hair color. So I also wanted to give you guys a great little visual today to debunk some other developer myths that are out there and I think one of the biggest ones is that if you use a lower developer like a 10 or a 20 and you leave it in the hair twice as long you can expect just as much lift as if you had used 40 volume or 30 volume right off the bat and that pretty much just isn't true. Developers are only going to work for a certain amount of time and you need to pick the developer that is going to give you the amount of lift that you want. I think one place that this is definitely played in big in my life is when I do my balayage with my guests thinking that you want to make sure that you go in there with a strong enough developer to get the kind of lift that you're going to want and don't think that just hanging out twice as long is going to give you something just as strong as a higher developer. So the visual that we've chosen to use is some cold tablets that get nice and fizzy with water and I've got four different cups here. They're going to be representing 10 volume, 20 volume, 30 volume and 40 volume and you're going to see as we drop them into the water there's going to be lots of energy varying levels of just crazy science that's going on but they're all going to work about just as long which is going to represent using a different developer with a different lightener. So if I can just get an extra set of hands here so we can get them all at the same time. Hi Matt. Hi. Alright ready? Three, two, one. That's fun. And they're off. And they're off. So as you can see as they get going they're all bubbling and fizzing at just different energies. Your 10 volume over here it's working but it's not working nearly as powerful. You're not seeing as much reaction as you are here with the 40. And as I timed it out earlier they last about 36 seconds. So they're all going to work. They're all doing their job just like a developer is going to but as it starts to slow down you see they're all slowing down at about the same pace and then in just a few seconds here they're all pretty much just going to stop right at the same time and that should represent the same expectations that you should have from your developers. They're all going to stop working about the same time. You need to take into consideration how much energy you want to have with your chosen developer. So I hope that helps you guys. Hope it cleared some things up for you. Had a couple of aha moments in there. Thank you so much. Stay tuned for step four and check us out at freesaloneducation.com. Thanks.
