London Fog - Monster Hair Dye

Maximum Purchase:
3 units

Shade: London Fog / Smokey Blue Violet when applied to pale yellow/blonde hair. Color will appear more vibrant on platinum hair, less vibrant on darker hair.

Monster Hair Dye is a vegan and cruelty free semi-permanent formula that conditions your hair as it colors. Our formula will not damage hair and does not contain peroxide or ammonia. 

Contains: 8.4 FL OZ (250ml) of product. No Gluten, Ammonia, Peroxide, PPD or Animal by-products. 100% Vegan and Cruelty Free. 

Note: Color will deposit onto the hair differently than how it appears in the bottle. A strand test is highly recommended.

Patch Test:

  1. Clean a small area of skin in an inconspicuous place such as behind the ear or nape of neck.
  2. Apply a dab of Monster Hair Dye to the area and wait 24 hours.
  3. Examine the test area for any signs of burning, swelling, redness or irritation during those 24 hours. If there is no reaction, you may proceed to color your hair.


  • We recommend pre-lightening hair to a pale yellow or platinum blonde for brightest color results. The darker the hair, the less vibrant the end results will be.
  • We highly suggest testing color on a small area of hair before proceeding with a full application of color to ensure end color results are to your liking.
  • Shampoo and dry hair completely before use. Do not use conditioner.
  • Apply a protective balm/cream around the hair line to preventing staining of the skin.
  • Separate hair into 4 sections and apply color evenly with a tint brush. Use gloves. Make sure to fully saturate and massage color into hair.
  • Leave on for at least 35 minutes for full color saturation.
  • Rinse with cool water for your first wash until the water runs clear. Do not shampoo or condition afterwards.
  • To prolong the life of your hair color, use a sulfate free shampoo designed for color treated hair, wash and rinse hair with cool water, avoid heating tools, chlorine/bleach, frequently washing your hair or using alcohol based hair products. Dry shampoo will become your best friend.

  • Color not quite what you expect

    Posted by Mel on 15th Jan 2018

    If you're expecting that beautiful, smoky purple shown in the sample strand, you may be in for a surprise. When first died it's MUCH darker than the color sample. It looks way closer to the "It's a crime" sample. It's more of a really vibrant dark purple. After a couple washes it's looking like it does in the pictures, so if you're going for that smokey lavender kind of color like I was, I would dilute the dye with some white conditioner first. Maybe it's because I did it on platinum hair, though I would of expected it to be brighter, not necessarily darker. The dark purple isn't bad, it's just not the color I was going for.

    This is the hair dye of my dreams. I put it over a darker golden blonde rather than platinum, and it still looks fantastic. It's was a great bright perrywinkle at first, then after a few washes faded to a nice lilac /lavender. I was surprised how intense it was on my darker blonde, because sometimes colors in this range just look weird or don't work at all over anything but bleached hair. I didn't heavily saturate the dye when I put it in, so I imagine if I had been more liberal with my application it would be even more vibrant. manic panic fades to gross after like one wash for me, this stuff is doing a much better job staying in than a lot of dyes I've used. There's a really decent amount of it too, which is awesome. I will absolutely purchase this again and again.i can't wait to see what it looks like on my hair when I get it even lighter!
