For blonde, highlighted, bleached, platinum, silver and grey hair, and ash tones, that turns brassy or yellow between colour services. Mon Platin designed it for lightened hair that is also dry or fragile. It is a home-care toning shampoo; no mixing is needed.

Purple shampoos often fix the tone but leave bleached hair even drier. Hyloren Blonde Highlights pairs the violet toning pigment with hyaluronic acid, so each toning wash also puts moisture back into hair that lightening has weakened. You get a cooler, brighter blonde on hair that feels softer and breaks less.

• Apply to wet hair and lather.
• Leave on for 2 to 5 minutes to tone.
• Rinse thoroughly.
• Use 1 to 3 times a week or as needed.

Pros:

• Tones out yellow and orange brassiness while also hydrating
• SLS/SLES-free and pH-balanced, so it is gentle on bleached hair
• Adjustable toning: leave it on longer (up to 5 minutes) for a stronger effect

Cons:

• Purple pigment is meant for lightened or grey hair, not for dark, unlightened hair
• Leaving it on too long or using it too often can leave a violet cast on very light or porous hair, so start with the shorter time
• Not designed for every wash: Mon Platin suggests 1 to 3 times a week
