awesome post lets not forget, ur 2 day hold might be 3 days or 4 or only 1 for someone else. im def going to try and mix them. using the hair color bottles seems like a great way of mixing and easily storing this homemade concoction i hope we all continue creating these homemade recipes. maybe we can one day continue getting this easy maintenance with even stronger hold times. maybe we should try mixing spirit gums with these?
