You just stepped out of the salon with the perfect icy platinum blonde shade of your dreams. Now, first things first: How do you keep that white blonde hair looking bright? Platinum hair is considered a high-maintenance color because of the frequent touch-ups needed to keep up with regular hair growth and the effort required to take care of your color at home. However, the extra TLC can be worth it to maintain that icy shade of white blonde hair. Plus, we’ve got all the guidance you’ll need when it comes to how to keep your hair platinum blonde and stave off brassiness until your next appointment with your colorist:

• Use a sulfate-free shampoo and conditioner

• Try purple products

• Introduce a bond building treatment

• Air dry to limit heat styling

How to maintain platinum hair: Tip #1

Use a sulfate-free shampoo and conditioner

Because coloring hair platinum blonde requires bleaching, the process is inherently damaging. Using a gentle shampoo and conditioner that’s free of sulfates is a great first line of defense. Redken Acidic Bonding Concentrate Shampoo and Redken Acidic Bonding Concentrate Conditioner feature sulfate-free formulas that were specifically created with damaged hair in mind. A bonding care complex and citric acid helps support hair on the molecular level by capturing metal ions and strengthening weakened bonds in each strand of hair.

Try purple products

One pitfall with platinum blonde hair is that it can start to look brassy, which is a yellowish-orange cast. If you’re wondering how to keep platinum hair from turning yellow, using purple color-depositing products can help. Surface Violet Shampoo and Surface Pure Blonde Violet Conditioner contain maqui berry, which has a naturally deep purple hue to help counteract brassy tones in platinum blonde hair. Both formulas also feature moringa and babassu oils to help nourish your hair and enhance shine.

Two of the best purple shampoos and conditioners for white blonde hair are ColorProof Daily Blonde Shampoo and ColorProof Daily Blonde Conditioner, which work together to cleanse and condition your hair while addressing dryness caused by lightening treatments. They’re highly concentrated, so you only need a small amount each time you use them.

Another way to keep platinum hair from turning yellow is to use a once-weekly purple hair mask. PHYTO Purple No Yellow Repair Mask is formulated to neutralize unwanted warm tones that can develop in platinum hair as a result of natural oxidation. The color-depositing purple pigments in this mask help keep your white blonde hair looking cool while boosting moisture with jojoba seed oil and shea butter.

How to maintain platinum hair: Tip #3

Introduce a bond building treatment

The process of bleaching your hair to achieve that perfect icy shade can leave your strands feeling brittle, dull and prone to breakage. Consider introducing a strengthening hair repair treatment such as OLAPLEX’s classic combo, OLAPLEX No. 0 Intensive Bond Building Hair Treatment and OLAPLEX No. 3 Hair Perfector. These products comprise a weekly two-step pre-shampoo treatment to help strengthen hair and reduce breakage with Bisaminopropyl Diglycol Dimaleate, OLAPLEX’s patented hair-repair ingredient. You start by spraying No. 0 Intensive Bond Building Treatment on dry hair. After it’s set for ten minutes, you apply No. 3 Hair Perfector from roots to ends and wait another ten minutes before shampooing and styling your hair as usual.

How to maintain platinum hair: Tip #4

Air dry to limit heat styling

If you frequently use blow-dryers, hair straighteners or curling irons to style your platinum hair, this tip might be a tough one to hear: One way to help keep hair icy blonde is to avoid heat styling as much as possible. “High heat damages your hair’s keratin structure,” says Dr. Joel Schlessinger, a board-certified dermatologist as well as Mohs surgeon and cosmetic surgeon. “When your hair is already weakened from the process of bleaching, using a lot of heat tools on it can be a double whammy of damage.”

Give your platinum hair a break from heat tools with styling products that are formulated to help give hair shine and shape as it air dries. Kenra Professional Air Dry Creme 6 helps keep frizz in check while providing flexible hold that lasts all day. Another option is Verb Ghost Air Dry Whip, a styling cream that helps give hair lightweight definition and frizz reduction with moringa oil, mushroom extract and vegan proteins.

If your platinum blonde hair is also curly or wavy, you might like to give the Curly Girl Method a try. You can learn all about this technique and other hair care tips on the LovelySkin Blog.
