I have to say, I don't typically read the warnings on home hair coloring kits because I have been coloring my hair since I was 13 and they typically all say the same thing. However, I noticed John Frieda's included some things I have never seen before like you need to remove all accessories you are wearing and cannot use metal tools. Since there seems to be an issue with metal, I assumed that the accessories they meant were jewelry. So I removed my earrings.
It also says you shouldn't use this product if you have a temporary black Henna tattoo, as it is likely to increase an allergy risk. If you wear contacts, you need to remove them also...however I'm not sure how you could put on your glasses since you can't have metal around. If you've colored your hair previously with compound hennas, metallic dyes or color restorers you have to wait until your hair has grown out and then cut. And don't try to put the foam on your eyelashes or eyebrows because it may cause blindness.
So, basically, by the time I was done reading that I was freaked out. Then I went on to read how to mix the product. It says you cannot shake the mix (you need to gently tilt it 5 times,) you cannot use the pump but instead have to squeeze the bottle to make the foam come out of the pump...which is psychologically confusing because you are holding a bottle with a pump...that you cannot pump. The bottle needs to remain upright at all times and you can only apply the foam to your hands first (in gloves of course) and not directly onto your hair. So basically I felt I was going to mess this up big time.
Application was tricky because the instructions state that you cannot get the foam on your face or ears at all. My hair is shoulder length, so good luck with that Shannon! Trying to prevent the foam from touching my skin, while trying to keep the bottle upright and not pump it was like playing a game of Twister.
Additionally your hair needs to be "frothy" with foam in order to be "done." Ok, guess what? Foam evaporates or absorbs into your hair. Especially if you have long-ish hair and are trying to make sure you get each section equally. Wait time from this point is 30 minutes. I rinsed my hair, applied the conditioner, rinsed that out after 3 minutes and then blew it dry. I was pleasantly surprised with the color. I loved it. Tweeted about it. My 7 year old snapped my pic for me and I was happy I was still alive with great looking hair.
Fast forward 1 week and while my hair is still brown, as you can see from the picture...the color has significantly faded. Ugh. I do not wash my hair everyday, in fact I usually only wash it every other day. I also used sulfate-free shampoo and conditioner, so I know it wouldn't have been the culprit to strip my hair color. I also hadn't washed my hair 24 hours before applying the foam as the instructions stated and I did not have any product build-up to prevent the color from adhering. So was it worth it to save myself the $60-$75 of coloring my hair at the salon? Not really. Have you used John Frieda's Precision Foam? I'd like to hear about your experience (good or bad.)
