- 3.1x More Hydrated: Clinically proven to significantly increase moisture levels in the hair immediately after application.
- 72-Hour Moisture Retention: Keeps hair feeling soft and hydrated for three full days.
- 69% Frizz Reduction: Smooths the hair cuticle to drastically reduce flyaways and frizz caused by humidity or dryness.
- Weightless Shine: Delivers a high-gloss finish that looks healthy and vibrant without flattening fine hair.
- Thermal Protection: Shields the hair from heat styling damage up to 450°F (232°C).
- Enhanced Elasticity: Improves the hair's natural bounce and resistance to mechanical breakage.
- Hyaluronic Acid: A potent humectant that holds up to 1,000 times its weight in water to intensely moisturise.
- Squalane: Mimics the hair's natural lipids to prevent moisture loss while restoring suppleness.
- Polyglutamic Acid: Works alongside Hyaluronic Acid to form a protective film that locks moisture deep within the hair shaft.
- Hibiscus Seed Oil: Rich in Vitamin E and essential fatty acids to provide superior shine and softness.
- Sea Buckthorn (Obliphica): amika’s signature superfruit, loaded with Omega 7 and antioxidants for overall hair health.
- Silicone-Free: Provides incredible slip and shine without the risk of heavy residue or long-term buildup.
- Clean Beauty: Vegan-certified and free from sulfates, parabens, phthalates, and mineral oil.
- 1. Preparation: Start with 1 to 2 drops (a little goes a long way due to the concentrated formula).
- 2. Damp Hair (Hydration): Apply to clean, damp hair from mid-lengths to ends before air-drying or blow-drying to lock in moisture and protect from heat.
- 3. Dry Hair (Finishing): Use a tiny amount to tame flyaways, seal split ends, and add a final "pop" of brilliant shine.
- 4. Pro Tip: For an intensive hydration overhaul, mix a few drops of Water Sign into your amika Hydro Rush Mask before applying to the hair. This creates a custom "moisture cocktail" for extremely parched strands.
Will this oil make my fine hair look greasy?
Not at all. Water Sign was specifically formulated to be silicone-free and lightweight. Because it uses skincare-grade hydrators like Hyaluronic Acid, it absorbs into the hair fibre rather than sitting on top of it, providing shine without the weight.
Does this provide heat protection?
Yes. Water Sign provides thermal protection up to 450°F (232°C). It is an excellent choice for protecting dry hair during blowouts or before using a flat iron.
Can I use this every day?
Absolutely! It is gentle and lightweight enough for daily use to refresh shine and manageability. If you have very fine hair, we recommend starting with just one drop and focusing on the very ends of the hair.
