Synthetic hair doesn't react to hair dye chemicals well, so make sure to invest in real hair that hasn't been dyed or chemically treated. Quality human hair extensions generally come in a natural brown (1B) color, so dyeing it is the perfect way to customize your high-quality hair. It can be more expensive, with prices ranging from $80-$500, but natural hair will look more natural, last much longer, and be easier to style. Before you start, make sure your extensions are clean and free of product buildup. Gently wash them with shampoo and lukewarm water, then use a towel to dry off the excess water. Leave the hair slightly damp before you dye it. This will cause the hair cuticle to open, speeding up the dyeing process. If the hair is brand new, you don't need to wash it. Just spray it with some clean water to dampen the strands. If you want to leave a section of roots, measure out about 1.5 to 2.5 inches (3.8 to 6.4cm) of hair at the top of the extensions. Use a ruler as a reference while dyeing to keep the line fairly consistent. For an ombre effect, where the hair color gradually lightens partway down the head, measure out where you want the hair to start getting lighter. Think about whether or not you'll need to bleach hair first or multiple times in order to achieve the color you want. If you want to dye your weave a bright color like blue or pink, you'll need to bleach it first. This will help the colors show up and have more brilliance. If you want to dye your hair darker, such as a jet black color, you won't need a pre-bleaching step. The products used to dye and bleach hair can be extremely harsh, so make sure to take some safety precautions before you get started. Wearing a pair of latex or rubber gloves will protect your hands from being dyed or bleached. Opening up some windows in the room will help ventilate the strong fumes. If the room you're in doesn't have proper ventilation, you should wear a mask over your mouth and nose to keep from inhaling the fumes. While dyeing, you should also wear some old clothes that you don't care about, such as an old T-shirt and sweatpants, in case the products get on them. Spread the damp strands out slightly so none of the hair is bunched up. If your wefts come packed in spirals, loosen the spiral and spread the hair out to make it easier to dye. Use a sheet that's large enough to leave some extra foil on the sides, which you'll use to wrap around the hair later. You can find hairdressing foil at a beauty supply store.

Summary: Use bundles of virgin hair for the best dye results. Wash your hair with shampoo to remove any product residue. Measure out where you want the dye to start. Consider the color of your weave before you choose a dye color. Put on latex gloves and open a window before you start dyeing. Lay the extensions out on a sheet of hairdressing foil.

Are they true blue, gray, green, hazel, or brown? Different eye colors "pop" with different eyeshadow colors. Brown eyes don't really have a specific palette. Fortunately, they look good with almost anything. You can add warmth to your eyes with red-browns and metallics, or you can play up your look with darker colors or brighter jewel tones that other eyes can't get away with as easily. For blue or gray eyes, the best choices for a little pop are warm copper and brown tones. For drama or to highlight the blue, wear a smoky gray shadow (or liner!). For other colors, generally steer towards pinks and pastels. If you have lighter eyes, colorful eyeshadow that is darker than your eye color can be overpowering. For green eyes, purple is your best friend. If you want a little dramatic flair, try a purple that's almost black for double the effect. Hazel eyes get a little more variety. If your eyes are greener, opt for the purple palette that makes green eyes look glamorous. If your eyes have more brown or flecks of gold, play that up with warm brown and gold tones. Don't forget about your skin tone. If your smoky eye turns out looking more like a bruised eye, then you might need to factor in your skin tone and whether your skin is fair, olive, or dark. Fair skin goes far with light colors, like pastel peaches and pinks, but bright and bold tones are too pronounced, leaving everything else looking washed out. Similarly, darker skin could appear ashy if you use a cool blue or grey. If you're having trouble figuring it out, pick up a cheap palette with a wide array of colors and experiment with your eyes. This is usually pretty easy to figure out for most colors and skin tones. For instance, if you're fair with a cool skin tone, you probably already know that an orange-toned lipstick will make you look strange. There are two things to consider when you're choosing lipstick colors. First, use your skin color to guide you toward the right color range. Fair skin plays well with bold and bright colors. Olive, neutral, or medium skin works with most colors, just avoid ones that will look pale. Dark skin pairs with richer, deeper colors, like wine or bright red. Second, narrow down your selection by factoring in your skin tone. Warmer skin tones pair well with warm base notes. When you're choosing a red lipstick, for example, you can easily wear a brick red or one with more orange to it. Cooler skin tones work best with pinks, blues, and purples. Your ideal red lipstick is more berry than brick or has a little plum in it. The theme here is that whatever you put on your skin should work with your skin's natural pigmentation. Cool skin tones should wear pink blushes that go well with their naturally rosier tendencies, or try pinker peach tones. A warm skin tone will shine with golden undertones, more towards the beige, orange peach, and apricot end of the spectrum. If you're lucky enough to have neutral skin tone, play around with different colors depending on your mood. If you're unsure how bright or dark to go with the blush, use your skin color as a guide. Fair skin works great with pastel pinks, while dark skin requires rich, bold colors like red-toned browns and oranges. Olive skin has a little more room to play around, but still leans more towards the pink end with room for darker, brighter colors than fair skin.
Summary: Base your eyeshadow selection on the color of your eyes. Use your skin tone and color to determine your lipstick shades. Pick a blush using your skin tone.
