FOUR REASONS Color Mask — Cool Sand Blonde Semi-Permanent Color-Depositing Conditioner, Neutralizes Brass, 6.76 fl oz

FOUR REASONS Color Mask in Cool Sand Blonde is a semi-permanent, color-depositing conditioning mask designed to neutralize yellow tones and refresh cool sandy blonde shades while improving shine and softness.

This leave-in-in-shower toner and hair gloss works as a temporary color refresher between salon appointments. Formulated without sulfates and enriched with plant-based proteins and amino acids, the mask deposits a soft sandy-beige pigment on lightened hair to reduce brassiness, boost gloss, and add conditioning benefits. Suitable for color-treated blonde hair that needs tone correction or a brightness boost, the product is part of FOUR REASONS' Color Mask range (available in 27 shades) and comes in a 6.76 fl oz tube.

How does this mask neutralize undesired yellow or brassy tones?

The Cool Sand Blonde formula uses semi-permanent pigments that counteract warm yellow undertones by depositing an ash-leaning sandy beige tint. Because it's a color-depositing conditioner, it both tones and conditions, blending away brassiness without the commitment of permanent dye. Results depend on your starting level of lift and hair porosity; lighter, more porous hair will show the effect more quickly.

• Deposits cool sandy-beige pigment to reduce yellow tones
• Visible results in 5–10 minutes during a shower application
• Works best on pre-lightened or naturally light blonde hair
• Temporary: fades gradually with subsequent washes

Can I use it at home and how simple is the application?

Yes — the mask is designed for easy at-home use as a replacement for your regular conditioner. Apply to clean, towel-dried hair, leave on for 5–10 minutes depending on desired intensity, then rinse thoroughly. The process is quick and salon-like, so it’s ideal for touch-ups between color appointments.

• Use in place of conditioner during shower routines
• Apply evenly from mid-length to ends for consistent tone
• Adjust timing (5–10 minutes) to control depth of deposit
• Rinse well; repeat weekly or as needed to maintain tone

Is this safe for color-treated hair and what are the key ingredients?

FOUR REASONS Color Mask Cool Sand Blonde is formulated to be color-safe and sulfate-free, reducing drying effects common with some toning products. Plant-based proteins and amino acids help strengthen and smooth the hair shaft while delivering the pigment, so your blonde appears shinier and healthier. Because it’s semi-permanent and vegan, there’s no long-term commitment and no animal-derived ingredients.

• Sulfate-free formulation for gentler care of color-treated hair
• Plant proteins and amino acids for conditioning and strength
• Vegan and cruelty-free labeling suitable for conscious shoppers
• Semi-permanent pigment that deposits without bleaching

How often should I use it to maintain salon-fresh blonde?

Frequency depends on how quickly your color fades and your desired tone, but many users replace their regular conditioner with the mask once a week to preserve coolness and shine. If your hair shows heavy brassiness, you can increase use to twice weekly until the tone balances. Monitor hair condition — reduce frequency if dryness or build-up occurs.

• Typical maintenance: once weekly as a conditioner swap
• Heavy brassiness: up to twice weekly for quicker correction
• Reduce use if hair becomes weighted or slightly dull
• Best results on lightened, porous, or naturally blonde hair

Who is this for: FOUR REASONS Color Mask in Cool Sand Blonde is aimed at anyone with lightened or naturally blonde, color-treated hair who wants a temporary, easy way to reduce yellow tones and refresh cool, sandy-beige color between salon visits. It suits shoppers seeking vegan, sulfate-free care that conditions while depositing soft pigment, and is practical for at-home maintenance when you want salon-like tone without permanent commitment.
