Overview
Schwarzkopf Keratin Color is a permanent cream hair dye in a deep Ruby Noir shade, sold as a full at home kit. A pre-color serum, the color cream with developer and a bond conditioner work as a three step routine.
Gray coverage and conditioning steps in one box make it a full home salon session. Anyone with hair past the shoulders has to buy a second kit.
Who it's for
Home colorists with gray strands and normal hair get a complete kit with gloves and aftercare. Those with long or thick hair, or wanting a gentle rinse, should plan differently.
Pros and cons
- Covers gray in one step
- Pre-color serum with vitamin B6, collagen
- Conditioner with K-Bond Plex included
- Disposable gloves included
- Long hair needs two boxes
- Permanent shade cannot be washed out
- Red black tone may read darker than expected
Performance notes
Permanent dye uses developer to open the cuticle so pigment settles inside the strand, which is how it covers gray. The serum and bond conditioner aim to limit the dryness that process causes.

Frequently asked questions
How do I keep Schwarzkopf Keratin Color Ruby Noir from fading?
The kit includes a post-color conditioner with K-Bond Plex for aftercare, and the brand describes the color as fade resistant. No further care routine is listed.
Does Schwarzkopf Keratin Color work on previously dyed hair?
Yes. The description says it suits refreshing previously color-treated hair.
Is Schwarzkopf Keratin Color semi-permanent?
No. It is a permanent hair color, so it grows out rather than washing out.
What does the 5x stronger claim on Schwarzkopf Keratin Color mean?
The footnote says it is measured against combing breakage on damaged hair compared with a non-conditioning shampoo. The description also mentions breakage reduced by up to 80%.
