INH Semi-Permanent Hair Color — Dark Blue Royal Sapphire, 6oz | Conditioning, Vegan

INH Royal Sapphire is a semi-permanent, color-depositing hair conditioner that adds vivid dark blue color while conditioning hair with baobab oil and glycerin — no developer required.

If you want a bold blue shade without long-term commitment or harsh chemicals, this 6oz jar gives you a rich, jewel-toned result you can apply at home. The formula is ready-to-use, vegan, and free from peroxide, ammonia, sulfates, and parabens. It’s designed to both tint and soften hair, gradually washing out over multiple shampoos so you can experiment with color without bleaching or permanent alteration.

How do I use Royal Sapphire for the best color payoff?

Apply to clean, towel-dried hair for the most even deposit. Wear gloves, apply a generous layer to the sections you want colored, and leave the product on for 30–60 minutes depending on desired intensity. Rinse with cool or lukewarm water until it runs clear and style as usual.

• Work on uncoated, detangled hair for even saturation.
• 30 minutes for subtle tone; 60 minutes for deeper pigment.
• Use cool water to help seal color and prolong vibrancy.
• No mixing or developer required — application is beginner-friendly.

What results should I expect on different starting colors?

Final shade depends on your base color. On lightened or blonde hair, Royal Sapphire shows as a vibrant, jewel blue; on darker hair it adds a deep blue sheen or subtle blue-black tones. Colors fade gradually with each wash, shifting to softer blue hues over time.

• Bleached or very light hair: brightest, truest Royal Sapphire color.
• Medium brown hair: noticeable blue tones and shine.
• Dark brown to black hair: blue tint, low saturation, and shine.
• Expect progressive fading — color diminishes with regular shampooing.

Is Royal Sapphire safe for my hair and scalp?

The formula focuses on conditioning and gentler ingredients rather than permanent chemical processing. It’s free from peroxide, ammonia, sulfates, and parabens, and contains Baobab Seed Oil and glycerin to help moisturize and reduce breakage while depositing pigment. Individual sensitivities vary, so a patch test is recommended before full application.

• Paraben-free, sulfate-free, peroxide-free, and ammonia-free formulation.
• Provides conditioning benefits while adding color.
• Vegan and cruelty-free — no animal-derived ingredients or testing.
• Patch test 48 hours before use if you have sensitive skin or scalp.

How can I make the color last longer and fade nicely?

Gentle care extends color life: wash with cool water, choose sulfate-free shampoos, and limit heat styling. Reapply the color-depositing conditioner whenever you want to refresh tone or maintain intensity; because the product is semi-permanent and conditioning, touch-ups are simple and non-damaging.

• Use cool or lukewarm water and sulfate-free cleansers.
• Limit frequent washes; dry shampoo can stretch time between shampoos.
• Reapply every few weeks to refresh or intensify color.
• Protect from sun and chlorine to slow fading.

Who is this for: INH Royal Sapphire is ideal for anyone seeking a bold dark blue hue without permanent commitment — from first-time color experimenters to color-savvy users who want vivid, temporary tones that also condition hair. It’s especially well suited to people with pre-lightened hair who want true blue saturation, and to those prioritizing gentler formulas free of harsh chemicals.
