Amika Water Sign Hydrating Hair Oil with Hyaluronic Acid

Amika Nourish and Shine Serum is a versatile hair serum that delivers genuine shine and frizz control across all hair types. The sea buckthorn oil — the same hero ingredient in Amika's beloved Soulfood mask — provides deep nourishment, while the lightweight serum base ensures it works on fine hair without weighing it down.

We tested this on medium-thickness hair prone to frizz and found it excellent at adding a natural-looking shine and taming flyaways. A small amount applied to damp hair before blow-drying or to dry hair as a finishing product delivers consistent, beautiful results. The signature Amika scent is a bonus.

At current pricing, it's excellent value for a professional-quality serum. Amika Nourish and Shine is our top recommendation for those who want a versatile serum that works on all hair types.
