Tip 3: Use Heat Protectant
High temperatures from heat styling can damage your hair and cause your colour to fade. To help prevent this, always use a heat-protectant like the L'Oréal Paris Elvive Dream Lengths Heat Slayer Spray, which protects your hair from heat up to 230 degrees.
Tip 4: Protect Your Hair From the Sun
Improper washing and styling aren’t the only things that can wreak havoc on ash blonde hair. The sun can actually cause your ash blonde hue to fade.
When it comes to protecting your hair from the sun, the rules are very similar to sun protection for your skin. According to the Cleveland Clinic, the best ways to protect your ash blonde hair are to stay out of the sun when possible, cover your strands with a hat, and invest in products with UV protection.
Tip 5: Invest in a Shower Filter
Even something as basic as showering can sometimes contribute to brassiness. Of course, it isn’t the act of bathing, but rather the minerals in your water supply that are the issue.
Thankfully, there’s an easy fix: A shower filter will ensure you can wash your hair without exposing it to hard minerals. Using the filter can help preserve your ash blonde hair colour for longer, especially when paired with a good shampoo and conditioner for colour-treated hair.
Tip 6: Try In-Salon Treatments
If you went to the salon for your new ashy blonde hair colour, your colourist likely explained the benefits of maintaining a regular salon schedule. But even if you opted to DIY your colour, your hue may benefit from regular salon toning services.
A hair toner is a type of semi or demi-permanent dye that allows you to alter the tone of your hue without changing the colour. Toners can help you experience a new type of blonde hair colour or correct brassiness to return your hue to its original ash blonde colour.
Your toning schedule will depend on how fast your colour fades, but many colourists suggest a refresh every six to eight weeks.
