## Description

Smart Beauty Sapphire Blue Black is a long-lasting permanent hair color hair dye kit offering midnight blue black hues. Its unique formula includes anti-breakage Plex Hair Care, which fortifies hair strength and condition while coloring, reflecting the brand's British heritage and commitment to high-quality, satisfying hair care products. The dye is designed to be gentle, aiming to minimize damage thanks to the anti-breakage Plex Hair Care, but a strand test is recommended to ensure hair integrity. For even application, start at the roots, comb through to the ends, and ensure a consistent spread of color for a uniform look. The Sapphire hair dye product boasts excellent coverage for grey hair and is suitable for use on various hair types, including chemically treated and different textures like Afro and Asian hair. This hair color for women provides a rich, enduring shade, and is equally suitable as a blue black hair dye for men. The hair dye is also a vegan product, aligning with ethical beauty standards by being free from animal-derived ingredients and cruelty-free. Smart Beauty black blue permanent hair dye can be left in the hair for 30 minutes according to the enclosed simple instructions. In the case of bleached or previously colored hair, follow the specific guidance provided to achieve optimal results. If you're concerned about a possible reaction to the product, it's vital to perform a patch test 48 hours before full application and consult a medical professional if any adverse reactions occur. To maintain the intensity of the blue black color, it is advised to use hair color-protective hair care products, limit washing, and reduce sun exposure. This careful maintenance will help preserve the vibrant color and the health of your hair after using Smart Beauty hair dye blue black permanent.

Review: نفس اللون لكن عليكي عمل تشقير بالاول لحتى يزبط اللون ويطلع نفسه.
Review: Definitely not permanenet - This product was very disappointing. At first I achieved the colour of purple I've been searching for for months. It was a wonderful shade, even on dark (dyed) hair. However this was short lived and within 2 washes my grey/white was showing at the roots and the length of my hair had turned a strange washed out pinkish colour. It wasn't cheap, yet it performed worse than any cheaper purple dye I've tried in the past. I will not be purchasing this product again.

### ⭐⭐⭐⭐⭐ Review
*by K***H on 6 September 2021*

I have previously had my hair dyed red by a professional, but being unable to get to a salon again during these times, I took the chance to touch up my hair at home. I also decided I wanted something more orange-red than the dark-red I had. This is definitely a bright orange shade, but after a few washes fades down a bit. I love it and have already ordered again.
