10 Best Longest Lasting Hair Dyes 2025 in the United States

The L'Oreal Paris Excellence Creme Permanent Hair Color in 4 Dark Brown is designed to provide 100% gray coverage, even on stubborn grays, making it a reliable choice for those looking to cover grays effectively. The triple protection system is a significant strength, as it not only seals and replenishes the hair but also conditions it, which is beneficial for maintaining hair health. This product is a cream type, making it easy to apply and ensuring thorough coverage from root to tip.

The inclusion of a weekly conditioning treatment with collagen helps protect the hair and extends the longevity of the color, which is a notable advantage for those seeking lasting results. The dark brown color is rich and should suit a wide range of users looking for a natural, deep shade. However, users should be prepared for a bit of aftercare to maintain the health of their dyed hair, especially if it tends to be on the drier side.

The product comes in a tub or jar, which may be less convenient than other packaging options. It’s also important to follow the included instructions carefully to achieve the best results and avoid potential issues. This hair dye is a solid choice for anyone needing long-lasting gray coverage with added hair care benefits, though attention to aftercare will be important to maintain optimum hair condition.

The L'Oreal Paris Superior Preference Fade-Defying + Shine Permanent Hair Color in 6AM Light Amber Brown offers a high-quality option for those seeking long-lasting hair dye. One significant strength is its fade-defying formula, which helps maintain vibrant color over time. Its gel form makes it easy to apply, and the included Care Supreme Conditioner with Shine Serum enhances the color's longevity while adding silkiness and shine to the hair.

Additionally, this product boasts a wide range of over 50 shades, allowing users to find the perfect match for their preferences, from natural tones to bold colors. This makes the dye versatile for covering grays, doing touch-ups, or experimenting with new colors. A notable advantage is L'Oreal's strong reputation and innovation in beauty care, ensuring that the dye is formulated with the latest technology for optimal results.

On the downside, while the product is effective in delivering long-lasting color, users must follow the aftercare instructions to maintain the best results. This includes regular use of color-protection products to keep the vibrancy intact. The dye's packaging could also be a consideration for environmentally conscious users, as it mentions compostable warning material features, hinting at some level of eco-friendliness. The L'Oreal Paris Superior Preference hair dye is a reliable choice for those looking for durable and vibrant hair color, suitable for various hair coloring needs.

L'Oreal Paris Feria Multi-Faceted Shimmering Permanent Hair Color in 45 French Roast offers a deep bronzed brown shade that is designed to provide long-lasting and vibrant color. This hair dye is known for transforming dull hair into a brilliant, multi-tonal look with its shimmering effect, which is great for those seeking a bold and edgy appearance.

The included Power Shimmer Conditioner helps to seal the color and provide smoothness, contributing to the longevity of the color and the health of the hair. This product is easy to apply with its gel form, making it suitable for home use without the need for a salon appointment.

However, it is important to follow the aftercare instructions to maintain the vibrancy and condition of the hair post-dyeing. One potential drawback is that, like many permanent hair dyes, it may cause dryness or damage to the hair if not properly cared for. Additionally, those with sensitive skin should perform a patch test to avoid allergic reactions. Despite these considerations, the product is a strong contender for individuals looking for a long-lasting, bold hair color with a shimmering finish.
