Dyeing dark hair without the use of bleach can help keep your hair safe from the damage of excessive bleaching. Overbleaching your hair can lead to brittle strands, split ends, and hair breakage, stripping hair of its natural oils and pigment. You don’t have to strip your hair to get a look you love, and when you protect your hair's integrity, you can experiment with color more often. Lemon juice is a natural hair lightener. To use lemon juice, spray a diluted mix of 50 percent lemon juice and 50 percent water and sit in the sun for 10 minutes. You can use a blow dryer if you don’t want to sit outside. If you want to play with some brighter or non-natural colors such as pinks, blues, and purples, eye shadow can be your undercover lifesaver. There are two ways to use eye shadow on your hair. The first, which is the simplest, is to take a little pot of eye shadow and apply it directly to your hair. Once you have the look you want, spritz some hairspray to seal it, and you’re ready to go. For the second eye shadow trick, you can use either a pressed or loose powder. Mix it with a face primer, and apply it to your hair. Seal it with makeup-setting spray, and rock your new look. Henna is a natural way to dye your hair. The henna colors are made from plants. Because they don’t contain bleach or other chemicals, henna dyes can't lighten your hair, but they can make it richer, darker, or more prismatic. Henna is a great choice if you’re looking to go darker or just have some variance in your hair; the dye nourishes and conditions your hair and scalp, giving your hair a glossy sheen. Some products on the market also color your hair without bleach. These dyes are made specifically for dark hair. They are usually semipermanent colors, and many use color developers. In other words, you’re still using chemicals on your hair, which can cause some damage, but less so than bleach. If you want to go lighter than more natural options allow, this is your best bet.
