I make shampoo and conditioner bars, and I finally found a few formulas that I love.
As a blonde, I would love them even more if I could replace my purple shampoo and purple conditioner. So I went ahead and ordered some Violet No. 2 External D&C.
I have been trying to do some research and am having trouble finding any information on how to tweak a regular shampoo formula into a purple shampoo. (I'd like to do conditioner too!) I did read that I probably won't need more than .3% in the formula for it to perform how I want.
Do I just go ahead and add the violet into my batch? Does it need to be added at a certain temperature? My shampoo bars are pH balanced to around 5.5-6, is that ok?
If you have any general tips or advice on formulating a purple shampoo and/or conditioner, please share. I greatly appreciate any advice - thanks!
