Kao Liese Bubble Hair Color

While in Hong Kong, I saw many ads on Liese hair color set that's supposed to color hair using bubbles. I also saw this on Ichibankao and Imomoko, so I thought why not give it a try. I haven't dyed my hair in over a year anyway.
The set cost $68HKD, cheaper than most hair coloring sets I've used. I got the Cassis Berry color.

It's pretty straight forward, mix the stuff and apply it to your hair. The pink packet in the front is a leave in nourishing conditioner after you've rinsed your hair. You can use a conditioner of your choice after you rinse the color out too.
My hair before. The color from last year is almost gone so it's back to super dark brown again.

Once you pour the little bottle into the large one, you put the white cap back on a gently tilt the bottle side to side about 8-10 times until it's mixed up. The instructions says you're not supposed to shake it like most other hair dyes, otherwise it'll create bubbles inside the bottle and therefore not come out properly.

After mixing, replace the white cap with the pink foaming top.

To get the product, you squeeze from the center of the bottle while keeping it upright. The foam comes out kinda light but it doesn't slip or melt.

I applied the foam gently all over my head before using my fingers to massage it in. Once you start massaging the foam in, it gets a bit thicker. The great thing about this foam is, there was no dripping and it didn't stain on my skin as easily as other hair dyes.

I waited for 30 minutes then rinsed it off. I was surprised the color rinsed off pretty quickly, then I applyed a generous amount of conditioner and let it sit for a minute before rinsing. Once I towel dried my hair, I apply the whole packet of leave in conditioner, which is enough for my length of hair and maybe not any longer.
The results afterwards...

It's great how it didn't drip and it was easy to apply. Even if I thought the foam was gonna start dripping while I waited, it didn't happen. The whole concept of the bubbles is so the product reaches the root of your hair because it's kinda liquidy. Also, it didn't sting my head at all.

The bad thing is, my hair didn't turn out as red as I thought! It looks more brown than red. I thought it was cool that the bubbles would easily go through my hair to get the roots, but I noticed the day after, the back underside of my hair wasn't colored properly. It was darker than the rest of my hair. Also, the smell of hair dye is so strong I could even smell a bit of it the next day, even after shampooing.

Would I buy it again? Yes, just because I like how I didn't get the bathroom messy with hair dye. I didn't even get it on my shirt. Even though it wasn't really even the first time I used it, I'm sure next time I could massage the color in better to get the underside of my hair.
