Method 1: Tinted dry shampoo
The product: Jet Set Black Dry Shampoo, $28, AG Hair.
The promise: To cover up roots between colourings and restyle limp, second-day hair with no white residue.
The verdict: Dry shampoo that won’t make me look like I have more greys then I already do? Life-changing. Compared with other brands I’ve tried, this worked really well to absorb oil.
Bottom line: The black dry-shampoo can transfer onto your hands (or onto the collar of a white blouse) if you run your fingers through your hair throughout the day. So either avoid wearing white clothes or stop playing with your hair.
Method 2: Pressed powder
The product: Rusk Deepshine Color Touch Up Compact Box, $15; refill, $20, Trade Secrets.
The promise: Instantly covers up roots and blends greys away until your next shampoo.
The verdict: This compact (that looks like an eyeshadow palette) requires no expertise—the small brush applicator applies a water-resistant powder that mutes stray grey hairs. For a deep side part, I liked using a larger applicator like a contour brush to cover more hair.
Bottom line: This product is for great for small areas like temples or along your part but not for major hair colour re-growth. The pressed powder easily blends into your natural hair, leaving no residue and tones down the silver-y bits.
Method 3: Tinted rinse
The product: Brilliant Brunette Visibly Deeper In-Shower Treatment, $13, John Frieda.
The promise: Weekly treatment that takes hair one shade darker and evens out tone in just 5 minutes.
The verdict: If you are looking to add richness and depth to your hair colour, this is for you. Massage into clean wet hair, comb through and set your timer. I like to clip my hair up while the product sets to keep the treatment concentrated and contained. Then rinse and voila!
Bottom line: Doesn’t disappoint, but better to think of this as a darkening gloss rather than touch up for your roots.
Method 4: Tinted spray
The product: Root Cover Up, $14, L’Oréal Paris.
The promise: Temporary root touch up spray that’s ammonia and peroxide free.
The verdict: It worked especially well when my roots were just growing in and the colour matched my hair perfectly so the coverage was seamless.
Bottom line: This was great for small touch-ups but when my roots were longer and I needed more coverage, it felt a bit sticky.
