I dye my own hair quite often (keeps down the salon costs!) Please make sure to do the strand test first, especially if you havent tried that brand before. If you have sensitive skin, most boxes included a rubber glover or two for your hands so I would use that as well.
A couple of tips I have found out through trial (and much) error:
**MAKE SURE ALL OF YOUR HAIR IS COVERED IN DYE! It’s super easy to miss a section or two of hair so make sure you get all of the “underneath” hair, the hair behind and around your ears and the hairline itself.
**Wear an old t-shirt or a button down…that way if you do glop a little bit on yourself, you won’t be upset.
**Don’t dye two radical colors so close together. Example: I went from blonde to red in 8 weeks and I came out of it blonde/punk rocker pink! LOL luckily, it looked cute so I kept it 😉
**If you do want to dye your hair two different colors in less than 12 weeks, I would recommend a Malibu treatment first. This should be done at a salon.
**Buy a shampoo and conditioner that is for color-treated hair, especially if you wash your hair often. This will ensure your color stays around for awhile.
**If you have a question whether the color is too light or dark…check your eyebrows! You will get a good idea whether this is a good color for your skin tone and whether or not you look silly (black eyebrows and platinum blonde hair is probably not the best match lol).
**Clairol, Herbal Essence, L’Oreal are all good brands that I have tried.
**When you want just a little bit of color, try highlights. You can get a kit at the store for these as well and sometimes this is a better alternative. It’s fairly easy to do highlights, most kits come with a comb/brush type of instrument to help spread the dye into straight, even lines.
**If you have dark hair and want to go red, try a brighter red. The color might scare you on the box but trust me, by the time it sets into your hair, it won’t seem like the same color.
**If you have a dark hair and want blonde hair, don’t choose a platinum/bleach blonde color the first time. Slowly work your way through the different blonde colors (ash, golden, medium, possibly strawberry).
**If you have blonde hair, don’t go dark brunette immediately. Why? Your roots will SHOW WITH A VENGENCE within 3 weeks. Unless you are ready for the upkeep and want to stay brunette for a long time, do yourself a favor and ease your way into that color scheme 🙂
**If you have red hair…ay yi yi. Your hair will never be truly blonde because the red will show too much and you will have to dye your hair raven black in order to get it brunette to erase the auburn streaks.
Hope some of this made sense but it is what I have learned over the years (and a little from beauty school, before I dropped out ;))
