Shoulder length, black hair initially

Prior to application I was really afraid that the dye won't show on my hair as I did not bleach my hair. I used only one bottle for shoulder length hair and it actually turn out great. Of course, the colour was not like how the examples shown, but I am still very satisfied with it, mainly because I have not ever bleach my hair and will probably not in the future as I might not be able to withstand the brightness. But this is definitely one of my all time fav colour for long term hair colour. 

I was sad that the color didn't show up @.@ 

Description: Temporary hair dye designed to fade after approximately a week, without damaging your hair.

Use: One time use 

- Mixed Bottle 1 into Bottle 2; mixed well

- Applied onto dry hair (instructions stated to apply on damp hair, though I applied on dry hair to obtain a stronger colour)

- Note: I have Asian black hair, and did not bleach my hair beforehand. 

- Left in for approx 30 - 40 min 

- Washed with water (no shampoo)

- Applied treatment

Pros:

- Product is very user-friendly; comes with gloves, etc.

- Hair dye doesn't smell awful like a lot of other ones out there

- Hair felt soft afterwards; same effect could probably be achieved by using conditioner and hair oils 

Cons 

- Dye colour did not show 

Overall, I give this a 1/5, as the product was not able to perform its main function, that is, dyeing my hair. 

this turned out great for me
