One Push 8 Natural Black - 2 Pack

I used the men’s version of this hair dye before (bought it in Japan), and now I tried the "women" version. It is basically the same, just as good! I really like the design and how convenient it is. It’s a two-in-one dye, so I can use it multiple times, which makes it super practical and great value. The color looks natural and it’s easy to apply.

This is one of the easiest & the most reliable dye for gray hairs in my opinion. Born and raised in Japan, Bigen has been a familiar brand name - I just didn’t realize I’d be using it myself one day! I can’t help but be partial to Japanese products, but this one is quite reliable - stays on well for about 3 weeks, keeps the natural appearance with shine, and I don’t see the dye transferring to pillow covers. I use the darkest black - which is my natural color. It’s perfect for my pitch black hair to cover the patches of gray that’s coming out of some random and inconsistent places on my head.

I love that this is so easy! You just comb through, wait 15 minutes then shampoo as normal. So easy. And for me, the color lasts a long time. I also like how the color is so natural. I use to have to buy this overseas, so I'm so glad there's a way to get it easier now. Awesome!

I like the ease of this hair dye. No mixing required. Goes on easily. I left on my hair for 45 mins and got full gray coverage. Like that it’s ammonia free so it will be less harsh on the hair. 4 stars for now until I see how long I can go without retouching.

I have used hair dye for more than ten years, and this hair dye is the most convenient and has one of the best effects. I highly recommend it to everyone.

I bought this last in February (a 2 pack). It’s now May and I just repurchased. With other products, I would have spent twice as much and dyed twice as much for my white roots. This is my forever product. The picture above is a photo of my current grey since the use of this product 3-4 weeks ago. So much easier on my hair.

Not sure if I need to keep it on for longer(?). It dyes but doesn't stay after 2 washes. I would notice some white hairs still after application as well. A bit disappointed in the result.

This is my go to product and does the job really well
