Senior Chemist Sabina Wizemann was also consulted during this guide's most recent update. With a background in hair dye research and synthesis, Sabina is passionate about all things hair-related. While working in the Beauty, Health & Sustainability Lab, she has led lab and consumer studies on at-home hair dyes, shampoos and conditioners for colored hair, hair serums, dry shampoos and more. She also tests hairstyling tools like hairdryers and curling irons, while staying on top of the latest innovations in hairstyling.
What is hair dye, and what does it do to hair?
This means that if you know how hair coloring chemicals interact, and you follow all instructions (never skip the instructions on the bottle!), you will not screw up. Permanent dyes penetrate deeper into the cortex of the hair, bleach the natural coloring, and trap color particles within the hair shaft. Hair damage can occur in any hair type, as it affects the inner and outer structure and makeup of the hair.
Who should use a green shampoo?
After your hair is dry, if you're unhappy with the color, you can mute it by applying a deep conditioner to damp hair. Leave on for 20 minutes (at 10 minutes, blast your head with a blow-dryer), then shampoo and condition your hair. If you're still not happy with your shade, well, it looks like you'll have to head to a salon when you can. Coloring your hair at-home can be challenging, especially if you're doing it all on your own. To make sure you get even coverage, McLean recommends having a friend to lend a hand (who you’ll need when you’re craning to make sure you didn’t miss a spot) to help with your at-home hair coloring journey. We'd be willing to bet that one of the last things you want is a stained hairline post-hair dye.

Most permanent hair dyes contain ingredients that can damage the hair. On the other hand, semi-permanent formulas can often be very nourishing, thanks to added conditioners. In cases where the hair has already been damaged by bleaching, adding pigment with a darker dye can actually be beneficial. Make sure to follow all the tips we've provided so far (wash your hair 24 hours in advance, detangle, etc.) beforehand, and then once you start applying the dye make sure to follow the directions. "Pay attention to recommended processing times—it’s easy to leave bleach on too long and the results are never pretty," warns Gould.

"Use silk pillowcases to decrease friction on the hair while sleeping to protect the hair strands as well," she says. The Food and Drug Administration (FDA) states that “organic” dyes aren’t necessarily any safer than those that are not organic. While they may have been sourced using different methods, organic dyes don’t necessarily mean they’re any safer. The degree to which bleach damages the hair depends on the pH (or acidity) of your hair and can also be affected by the pH of the environment around you.
According to a 2018 study, hair dyes containing conditioning agents such as hydrolyzed silk or milk protein may reduce the damage from dyeing hair. Most permanent hair dyes use a combination of ammonia, hydrogen peroxide, and p-phenylenediamine (PPD) to color the hair. Ammonia opens up protein layers in the hair, which allows the dye to coat the hair shaft.
If they fall more to blue and purple, you might have a cool undertone. Using shampoos that include lipids, such as fatty alcohols, can also help to replenish lipids in the hair and improve hair strength. Products labeled as “natural” or “organic” may also produce negative effects. Natural sources, such as plants, can still contain harmful or allergenic substances.
Best Natural Hair Dye Conditioner
Sorry, hair dye without any chemicals is just not a thing (again, unless you’re working with henna or straight-up plant juice). Dye will always require some chemical-based ingredients to help deposit pigment onto your hair. That said, you can get hair dye that’s made without alcohol, ammonia, or PPD if you want something less harsh, but still want to get in on all the newest hair color trends. My favorite thing about this natural hair dye is the thin application tip and gel formula—both of which make it so easy to target specific areas or strands if you aren't looking to color your whole head. Antioxidant-rich oat flakes and color-preserving flower extracts are just a couple of the standout ingredients in this one. "Any hair coloring process that includes lightening, lifting or bleaching should be avoided if you want to preserve hair structure and keep it in its best shape," Wizemann advises.

The nozzle dispenses the spray very evenly, so it’s very easy to apply. It’ll stay put in your hair until you wash it out, although it might also stain your pillowcase. Christophe Robin makes some of our favorite hair masks, and that includes this mask-dye hybrid. This rich, creamy mask conditions and moisturizes the hair deeply while also depositing just a light hint of color. It helps to gloss, tint, or enhance your color, and it works nicely both on natural and dyed hair.
You don't want your hair dye to go to waste if you don't end up needing it. Don't worry—the few minutes it takes to mix up that second box won't lead to an uneven color. TBH, showing a little root is no big deal, but when they start to take on a life of their own, it’s time to touch them up. All you have to do is shake this can, hold it about six inches away from your roots, and spray. Plus, it’s transfer-proof (just let it dry for a few minutes), so you don’t have to worry about it getting all over your hands.
The shorter amount of time that the dye is in contact with your hair means that it’s a little gentler than other formulas while still being able to change the hair color by a few levels. GH Institute Senior Product Analyst Emma Seymour is a fan of trying bold hair colors and recommends this Lime Crime formula, which comes in a large array of vibrant and unique shades. If you’re thinking about dyeing hair, you need to decide how much time you’re willing to spend on your hair. On the other hand, semi-permanent dyes last longer so you don’t need to touch more more than once a month, depending on how fast your hair grows and how many washes you do. Of course, permanent dyes will last even longer, but you do need to be sure you want to commit to a certain color for quite some time. There are a ton of hair dyes that are free of ammonia, alcohol, and p-phenylenediamine (PPD, a chemical that helps open up your hair cuticle to let the dye in).
"Be organized about the application," says Brooke Jordan, head stylist with The Bird House salon in NYC. "People can miss spots, or don't know how to get the back." To prevent this, use clips to create four sections and work through them front to back. Make sure you're comfortable (a pair of these luxe PJs should do the job), have everything you need (we've got you there below), and aren't pressed for time.
