Coastal GRL Zero Rinse Conditioner is an advanced treatment designed to replace your traditional conditioner. Powered by a targeted blend of treatment-level actives, it’s applied after the shower and stays in your hair, allowing it to properly absorb and deliver stronger, longer-lasting results.

Created by a hairdresser, it was developed to solve a common problem she saw every day — traditional conditioners and treatments stop working the moment they’re rinsed out. Zero Rinse changes that by staying in the hair, giving it the time it needs to truly work and improve overall hair health.

It also completely simplifies your routine and saves you time in the shower. You wash your hair as normal with your shampoo, step out, towel dry, and apply Zero Rinse — no need to condition or rinse anything out.

Because it stays in the hair, it also replaces multiple after-shower products, including your detangler, heat protectant, oil, and leave-in creams — all in one step.

Formulated with high-performance ingredients including keratin, a smoothing complex, heat shielding complex, plant repair complex, botanical moisture complex, and nourishing oils, it helps improve frizz, smoothness, shine, and strength, while acting as a heat protectant for healthier, more beautiful hair.

Coastal GRL Zero Rinse Conditioner is designed to absorb into the hair instead of being rinsed away like regular conditioner.

Because Coastal GRL Zero Rinse Conditioner stays in the hair, it continues working over time as it fully absorbs, rather than being washed out before it can deliver real results.

It’s formulated with stronger, treatment-level functions that help support hydration, smoothness and manageability for longer-lasting results.

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.

No. Coastal GRL Zero Rinse Conditioner is lightweight and designed to absorb into the hair without leaving a heavy or greasy feel when used as directed. If your hair is prone to oiliness, it’s best to use less product.

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.

Your regular shampoo is okay to use, preferably salon grade. Stay tuned — Coastal GRL will be bringing out a unique shampoo in the future (10ish months away)

Start with a small amount (around 2 pumps) and adjust based on your hair length and thickness, don’t use too much.

Coastal GRL Zero rinse conditioner is built with a carefully selected blend of hydration boosters, strengthening actives, and lightweight conditioning ingredients designed to support smoother, healthier-looking hair over time.

At the base, Aqua (Water) delivers lightweight hydration, supported by Glycerin and Sorbitol, which help draw moisture into the hair to improve softness and manageability.

To support stronger, healthier-feeling hair, we’ve included Hydrolyzed Keratin, Hydrolyzed Wheat Protein, and Hydrolyzed Glycosaminoglycans, helping reinforce the hair structure and improve resilience over time. Panthenol (Pro-Vitamin B5) helps boost hydration and enhance shine.

For nourishment and smoothness, Shea Butter Ethyl Esters, Simmondsia Chinensis (Jojoba), Helianthus Annuus (Sunflower), and Triticum Vulgare (Wheat Germ) help leave hair feeling soft, conditioned, and more manageable.

Amino acid–based ingredients such as Sodium Cocoyl Collagen Amino Acids and Cocoyl Sarcosine help maintain balance, while Lactic Acid supports the overall look and feel of the hair.

Vitamin-rich ingredients like Tocopherol and Tocopheryl Acetate (Vitamin E) help support overall hair condition and shine.
