Full details
Syoss Permanent Color 5.8 Brown is designed for adults seeking professional-quality, salon-finish hair color from the comfort of home. Its core benefit is high-intensity, long-lasting pigment that covers greys completely while strengthening hair with a specialized keratin mask for up to 100 days of shine. Users should be aware that, as a permanent chemical dye, a patch test is required 48 hours before full application to avoid potential skin reactions.

FAQs
Do I need to wash my hair before applying?
It is recommended to apply on dry, unwashed hair for better adhesion, unless your hair has heavy product buildup.
Can I save the leftover mixture for later?
No, once mixed, the developer and color cream must be used immediately; discard any unused mixture.
How long does the 5.8 Brown color last?
With proper care, the color can maintain its vibrancy and shine for up to 100 days.
Is this safe for sensitive scalps?
Always perform the 48-hour patch test as instructed. If you have a known history of reactions to hair dye, consult a dermatologist first.
What is the purpose of the keratin mask?
The mask is used after rinsing the dye to strengthen hair fibers from the inside and seal the color for a smooth, shiny finish.
Troubleshooting
Color did not cover grey hair effectively
Ensure the mixture was applied generously to grey areas and that the recommended development time was strictly followed.
Skin irritation during application
Immediately rinse with plenty of water and discontinue use. Ensure you perform a patch test 48 hours prior in the future.
Resulting color is darker than expected
Check your base hair color against the packaging guide; porous or bleached hair absorbs pigment faster, potentially requiring less development time.

Setup, Compatibility & Care
Before starting, confirm the product is compatible with your hair history, specifically if you have used henna or metallic dyes previously, as this may affect results. Store the kit in a cool, dry place away from direct sunlight. To maintain the 5.8 Brown shade, use color-safe shampoos and avoid excessive heat styling, which can degrade the color pigments over time. The kit is designed for a single-use application.
