Moehair USA 4VG Coffee Hair Color
The Moehair permanent hair color interacts with your hair’s natural pigment and alters its structure without affecting the hair strands. The permanent hair color dyes are tiny colorless molecules that help with easy color deposit. They penetrate the hair cuticle and create a chemical reaction when combined with hydrogen peroxide, known as oxidation. Permanent hair color molecules become complex through oxidation and embed themselves in the structure of the hair fiber. The result is a permanent hair color that can withstand multiple washes.
When applying permanent hair colors, it is important to consider your hair type for proper results. Coarser hair, which has a larger diameter, takes longer to absorb color, whereas finer hair absorbs color more quickly.

Ruth Simpson –
The coffee color applied evenly and stayed vibrant after two weeks of regular washing. My coarse hair took a bit longer to process, but the final result was rich and natural-looking.
Colin May –
I applied this color to my fine hair and noticed it absorbed quickly. The shade was consistent and didn’t fade too soon. Slight difference from the bottle sample, but still satisfied.
Jonathan Alsop –
Great for building a warm, medium brown tone. The oxidation process worked well, and the color settled into the hair without damaging it. I’ve used it twice now with no noticeable dryness.
