The right color
Color: Midnight Onyx
The correct shading that I wanted

Midnight Onyx is a no go
Color: Midnight Onyx
I was doing a split dye with two midnight colors, Ruby and Onyx. Ruby applied with no problem though didn't really rinse clear. Onyx didn't completely dye my hair. I thoroughly coated my hair and used a mirror to check and make sure everything was covered. I left it on for one hour. When I rinsed, the Onyx rinsed really clumpy and in chunks. I did everything the same between the two colors yet this one did not take 100% and I have chunks of undyed hair now. It's entirely possible I got an old box and I admit I didn't check any expiration dates, so just be wary.

Splat Midnight Onyx Semi Permanent Hair Dye Kit, 1 Application, Includes Deep Reconstructor
Color: Midnight Onyx
Splat Midnight Onyx Semi Permanent Hair Dye Kit, 1 Application, Includes Deep Reconstructor is a great product to have to dye your hair. Great Quality product not harsh on scalp or skin get a shiny smooth hair after using Splat dye. Quantity is good you get a 8 oz bottle of hair dye and a packet of conditioner. Great value for the money. Lasts pretty long about 4 weeks unless you wash it every day lol.

Not even slightly black
Color: Midnight Onyx
I've been a Splat user & completely happy with it for about 15 years. I just tried the "No bleach needed" black dye. I left it on until it dried, like I always do, then washed it out. ALL of it washed out. Not a single bit of black stayed in my hair. Highly disappointed. I deal with chronic pain, can't afford to go to a salon, so dying my own hair takes a lot out of me, only to find it didn't stick. I tried L'Oreal years ago & it was black black & stayed a very long time. In a month, I'll try bleaching & then dying to see if it works, if not, I'll go back to L'Oreal. It dyed my shower blue, but nothing stayed in my hair!

Gets the job done! Beware of skin staining and dark pigmentation on surfaces though. Other than that, pretty good 👍
