Salon visits can get undeniably pricey, but luckily, it’s never been easier to get great dye results at home — with minimal risk of brittleness, breakage, and dry strands. The least-damaging box hair dyes are low-ammonia or ammonia-free formulas, and some use conditioning ingredients to fortify and hydrate hair. Plus, you’ll have a range of options to choose from, so you can opt for permanent or semi-permanent dyes in a variety of colors and formulations.
When searching for the least damaging hair dye, keep in mind that both bleach and ammonia tend to be rough on strands. However, those ingredients are most effective at lightening and/or depositing color, so your results may be less dramatic with formulas that forego those them altogether. That being said, the tradeoff is likely worth it if you’re looking to preserve the condition of your hair. Speaking of ingredients, also be on the lookout for products that are infused with extras to help your locks recover, like keratin, natural oils, and silk extracts that add strength and moisture.
When it comes to hair dye that doesn’t damage hair, you won’t have to sacrifice choices, so consider what it is you’re after, whether that’s a permanent option that lasts indefinitely, or a semi-permanent dye that washes out in four to six weeks. You can also opt for natural-looking shades, vibrant colors that pop, dyes specifically formulated for grays, or even herbal formulas that capitalize on natural ingredients for ultimate peace of mind. And if you’re looking for the absolute least damaging hair dye, you may want to consider a color-depositing mask that performs as a deep conditioner as well as a coloring agent.
With all that in mind, here are the least-damaging box hair dyes you can buy.
