Sometimes you just feel moved to make a colorful change to your hair. Luckily, you don’t have to expose your locks to potent damaging dye elixirs to try out something fun and vibrant.

From semi-permanent coloring conditioners made without harsh bleaching agents to a marker-shaped dye that you can actually color onto your strands, there are plenty of gentle options out there.

So gentle, even the youngest bestie you know — we’re talking baby sis to babysitting, with permission of course — can get in on the fun. The biggest caveat, as with most temporary hair dyes, is that color may not show up as vibrantly or last as long on darker hair.

What’s “nontoxic” mean anyways? We chose the products on this list because they’re free of ingredients commonly known to cause skin or body reactions, like parabens, sulfates, and phthalates, or because they contain a very moderate amount of unwanted chemicals.
Keep in mind that this may not be an all-inclusive list. Even nontoxic products can cause allergic reactions in some people. If you’re using a product for the first time, make sure to test it out on a small patch of hair or skin around your wrist before going all in.

If you’re feeling ready to break out the gloves and experiment with something new or traditional, here are seven nontoxic hair dyes that you should check out.

Skip the bleach and go straight for the color with oVertone’s semi-permanent Coloring Conditioner, made for dark-colored hair.

1. Stick to temporary dyes

Semi-permanent and permanent hair dyes aren’t great, especially for kids, because they work by chemically altering the hair and causing long-term damage, says Pamela Schoemer, MD, a pediatrician at Children’s Community Pediatrics. Temporary dyes are lower risk as they simply coat each strand with color.

2. Avoid direct skin contact

This is good advice no matter what type of dye you use. “We recommend keeping [the dye] away from the scalp to decrease irritation and absorption,” says Schoemer.

3. Read the box

Regardless of age, Schoemer recommends closely following any accompanying dying instructions. If you have questions about the product or side effects, you should seek out a professional stylist or doctor.

4. Talk about it first

While coloring your own hair is a decision with less at stake, if you’re going to tackle another person’s hair, make sure it’s their decision, especially if they’re younger.

“Coloring the hair should be the child’s idea and I would talk about why they want to do this,” Schoemer reminds us. “It is great to find ways to express individuality or just have fun, but there is always a risk when using coloring products.”

If you remain concerned about possibly applying dye to a child’s hair, or even yours, Schoemer suggests totally skipping the process.

“It is OK to have fun [with hair color],” she says. “There are alternatives like wigs that may get the same results.”

And with continued concern from consumers about the contents of cosmetic products, hopefully we’ll see even more safe alternatives to traditional hair dye in the future.
