INH semi-permanent hair color — Royal Sapphire dark blue 6oz | color-depositing conditioner, no bleach & vegan

INH Royal Sapphire is a ready-to-use, semi-permanent dark blue color-depositing conditioner that tints and conditions hair without bleach, peroxide, or ammonia.

If you want vivid blue tones with minimal commitment and minimal damage, this royal sapphire hair dye deposits color while moisturizing hair. The 6oz jar arrives pre-mixed as a conditioning mask, so you can apply straight from the container—no developer or mixing required. Formulated to be vegan and free from sulfates, parabens, ammonia, and peroxide, the formula aims to refresh or transform hair color while helping to reduce dryness and breakage.

How quickly will I see the royal blue color and how long does it last?

Color payoff depends on your starting shade: lighter bases show brighter, more vivid blue; darker bases produce subtler, jewel-toned results. Expect initial vibrancy after one application, with gradual fading across shampoos rather than an abrupt loss of color.

• Apply for 30–60 minutes for best deposition.
• Brightest results on pre-lightened or blonde hair.
• On darker hair, expect a tinted sapphire sheen rather than solid blue coverage.
• Fades progressively with each wash; repeat applications build intensity.

Can I use INH Royal Sapphire without damaging my hair?

This formula is designed to deposit pigment without bleach or peroxide, so it won’t lift or permanently alter your natural color. Conditioning ingredients like baobab seed oil and glycerin help reduce dryness and add slip, making the dye suitable for fine, dry, or previously treated hair when used as directed.

• Free from peroxide, ammonia, sulfates, and parabens.
• Contains moisturizing agents to protect hair cuticles during color deposit.
• No developer or lightener required—reduces chemical stress compared with permanent dyes.
• Patch test recommended to check scalp sensitivity before full application.

How do I apply this color-depositing conditioner for best results?

Application is straightforward: wear gloves, section the hair, and work the conditioner evenly from roots to ends. Leave the product on for the recommended 30–60 minutes, then rinse with cool or lukewarm water to lock in pigment and shine.

• Start with clean, towel-dried hair for even coverage.
• Use a comb or fingers to distribute product thoroughly through each section.
• Rinse with cool or lukewarm water to help seal the color.
• Repeat applications every few washes or as desired to refresh color intensity.

Can I mix INH colors or create custom shades with Royal Sapphire?

Yes—these deposit-based conditioners can be blended to craft custom tones, create peekaboo effects, or tone down intensity. Because they are temporary and rinse out gradually, they’re ideal for experimenting with color combinations without long-term commitment.

• Mix small portions to test new shades before full application.
• Use with sectioning techniques for highlights, roots, or rainbow looks.
• Layering over previously colored hair alters final hue; test strand first.
• Fades to softer tints over multiple shampoos, offering evolving color options.

Who this is for: INH Royal Sapphire is aimed at people who want expressive blue color with low commitment—creative stylists, festival-goers, color experimenters, and anyone avoiding bleach or harsh developers. It suits those seeking conditioning color refreshers that can be applied at home without advanced technical skills. If you need permanent coverage or dramatic lightening, consider consulting a professional first; for safe, repeatable blue tones and improved hair feel, this product is a practical at-home option.
