Hair Color FAQs
How many boxes of hair color do I need for long or thick hair?
If your hair is past shoulder length or very thick, plan on two boxes for full coverage. One box can run short on saturation, which leads to patchy results. Using two ensures your roots, mids, and ends all get enough product for an even finish.
What’s the difference between permanent, semi-permanent, and temporary color?
Permanent color alters your hair’s structure to deposit long-lasting pigment and is best for big shade changes and grey coverage. Semi-permanent enhances tone and shine, fades gradually, and is great for refreshes. Temporary sprays and gels wash out after one shampoo, perfect for events or trying a new undertone without commitment.
How can I stop my blonde or light brown hair from turning brassy?
Use a toner or gloss with cool undertones to neutralize warmth, and switch to a color-safe routine. Limit hot water, protect hair from heat styling with a thermal spray, and use a violet or blue toning product weekly to keep brass at bay.
What’s the best way to cover stubborn greys at home?
Choose a permanent dye labeled for 100% grey coverage, usually in natural or neutral shades. Apply to roots first, ensure full saturation, and follow the full processing time. Between full colors, root touch-up powders or sprays are quick, low-commitment fixes that blend greys seamlessly.
How do I pick the right undertone if I’m unsure what suits me?
When in doubt, go neutral—it flatters most complexions and avoids unwanted warmth or ashiness. If your hair tends to go brassy, choose a cool (ash) tone. If your color looks flat, try a warm or neutral shade for added dimension. Checking real-life swatches and user photos can help you decide with confidence.
