WHAT IT DOES

Zero Rinse is an advanced leave-in treatment designed to replace your traditional conditioner. Powered by a targeted blend of treatment-grade ingredients, it goes on after the shower and stays in your hair instead of rinsing down the drain, so it keeps working long after a regular conditioner has washed away.

Why It Works

Zero Rinse combines a Long-Wear Smoothing System with a Plant Repair Complex and Keratin to help support hair structure and reduce breakage, Nourishing Oils and Botanical Moisture to help soften and reduce tangles, and a Heat Shielding Complex to help protect against everyday heat and styling.

HOW TO USE

1 - Shampoo
Wash hair as normal.

2 - Towel-Dry
Squeeze out excess water.

3 - Apply
Work around 2 pumps (adjust for hair length and thickness) through mid-lengths to ends, applying lightly at the roots.

4 - Leave In
No need to rinse.

ALSO GOOD TO KNOW
Bottle longevity (washing 3x/week, approximate): fine hair up to 11 months, medium hair around 7.5 months, very thick hair around 4 months.

Using alongside Advanced Shampoo: Shampoo with Advanced Shampoo, towel-dry, then apply Zero Rinse. Two products, full routine.

Meet Sarah

The Hairdresser Who Saw the Damage Firsthand

Sarah spent years behind the chair repairing sun-, salt- and chlorine-damaged hair, and got tired of only being able to fix it after the fact. So she created Pre-Swim: a leave-in barrier that helps to stop the damage before it happens, not a treatment that tries to undo it.

Every product since has followed the same rule: solve a real problem a hairdresser sees in the chair, not add another bottle to the shelf. Coastal GRL isn't formulated by a massive corporation, it's built by someone who's spent years solving these exact problems for real clients.

FREQUENTLY ASKED QUESTIONS

YOUR QUESTIONS, ANSWERED

What results can I expect from Coastal GRL Zero Rinse Conditioner?

Hair feels smoother, more hydrated and easier to manage, with improved softness, reduced frizz and healthier-looking hair over time.

It helps improve the look and feel of common hair concerns like dryness, frizz, split ends, dullness, rough texture and hair that feels hard to manage after washing — leaving your hair looking smoother, shinier and more put together throughout the day.

Will Zero Rinse make my hair greasy, heavy or cause buildup?

No, Zero Rinse is lightweight and designed to absorb without weighing hair down when used as directed. If your hair is prone to oiliness, start with a smaller amount.

What’s the difference between Coastal GRL Zero Rinse Conditioner and regular conditioner?

Regular conditioners are rinsed out before they can fully work. Coastal GRL Zero Rinse Conditioner is designed to absorb into the hair, helping deliver longer-lasting results without extra time in the shower.

What shampoo do I use before applying Zero Rinse?

Use your regular shampoo, preferably a salon-grade formula, or pair it with Coastal GRL's Advanced Shampoo for a full cleanse-and-treat routine.

How much Zero Rinse should I use?

Work around 3 pumps through mid-lengths to ends, applying lightly at the roots. Adjust the amount for your hair length and thickness.

Can I use Zero Rinse every time I wash my hair?

Yes, Zero Rinse is designed to be used after every wash, or daily if you prefer.

How long will one bottle of Zero Rinse last?

Based on washing three times a week, one bottle lasts around 11 months for fine hair, 7.5 months for medium hair, and about 4 months for very thick hair.

Can I use Zero Rinse with Coastal GRL Pre-Swim?

Yes. Pre-Swim helps protect hair before you swim, and Zero Rinse is applied after showering on non-swim days. The two work well together as part of the same routine.

Will Coastal GRL Zero Rinse Conditioner help with frizz and dry hair?

Yes. Coastal GRL Zero Rinse Conditioner has advanced treatment technologies that help smooth the hair and improve manageability to set hair up for the best outcome.

Can Coastal GRL Zero Rinse Conditioner be used on straight, wavy and curly hair?

Yes. Coastal GRL Zero Rinse Conditioner is suitable for most hair types, including straight, wavy, curly, colour-treated, non colour-treated, and dry or damaged hair.

Is Coastal GRL Zero Rinse Conditioner safe for chemically treated hair (keratin, nanoplasty)?

Yes. Coastal GRL Zero Rinse Conditioner is suitable for chemically treated hair, including keratin and nanoplasty-treated hair.

Is Coastal GRL Zero Rinse Conditioner safe for hair extensions?

Yes. Coastal GRL Zero Rinse Conditioner can be used on hair extensions. We recommend applying lightly and avoiding over-application at the bonds or roots.
