I've tried a lot of at-home hair dyes over the years, and One 'n Only Argan Oil Permanent Hair Color is hands down one of the best. This stuff delivers rich, vibrant color that actually lasts — and the best part? My hair feels healthier after coloring, not fried. The argan oil makes a real difference — no dryness, no straw-like ends, just soft, shiny, nourished hair. It glides on smoothly, covers grays like a pro, and doesn’t smell like a science experiment gone wrong. Total win. The color payoff is deep and multidimensional, not flat or brassy. I’ve gotten so many compliments, and people legit think I went to a salon. Nope — just this little miracle box. If you're looking for permanent color that leaves your hair looking and feeling amazing, highly recommend giving this a try. It’s become my go-to, and I’m not looking back.

Love this dye. It covers those stubborn grays too!

Very nice shiny not dull color. Great price.

I have been using Argon Oil One and Only hair coloring products for years. I love the rich color and how well it covers my gray hair. I almost always use the Medium Chocolate Brown color, and keep this as a foundation. But I have also used a variety of other shades as well. I brought this to my hairdresser to have her put it in, and she’d never heard of it. She absolutely loved the rich color and how well it covered. I also love how well it conditions my hair. I was pleased to find it on Amazon because it’s typically exclusively sold at Sally’s. Great product, and they offer many different shades and options for color choices.

Great quality product. The argon oils helps hair feel healthier. I purchased 3N since my natural hair is dark brown. However, the color was more black than anything. I used a 20 developer per instructions. I also have grays and the gray coverage was great. I only had the dye on for 30 minutes even though for gray coverage 45 minutes is recommended. Next time I will choose a lighter color. Other than the color mix up it’s a great product. Here’s a before and after photo.

I loved the product, it dyed my hair super black, I had never tried such a good hair dye, if you try it you will not regret it

Excellent product

Has more of a purple colour than black. Made my Grey roots and skin go purple. Terrible colour.

Good quality

Good One. My mother is using the same.

Leaves my hair feeling healthier than before, if that’s even possible! I believe this product is elite in the professional hair colouring world.. covers grays well, and leaves it shiny and refreshed. No powerful chemical smell, also one tube can do two applications if you have finer textured and medium length hair! A lot goes a long way!

I recommend all ladies use this item, it is amazing, my hair shiny and healthy
