This Is A Curl Building Serum A leave-in curl serum for wavy, curly, and coily hair — builds defined, bouncy, shiny curls with Panthenol and VP/DMAPA Acrylates Copolymer that block frizz and seal out humidity all day. The Moda Team Review The Curl Building Serum is for the client whose curls need more than a mousse can deliver — more definition, more hold, more humidity resistance. The VP/DMAPA Acrylates Copolymer is a flexible-film polymer that wraps each curl and holds its shape while blocking moisture from outside disrupting it. Panthenol adds elasticity and shine to the curl surface, so the result is defined and bouncy rather than crunchy or stiff. It applies to damp hair, distributes easily, and works on its own or as a base under the Curl Mousse for maximum definition and volume. The Winner InStyle Best Beauty Buys recognition reflects what we see at the chair: it genuinely outperforms most curl serums on hold and frizz resistance without the heaviness that many curl creams carry. Key Active Ingredients VP/DMAPA Acrylates Copolymer — flexible film-forming polymer that defines curl shape and seals the cuticle against humidity penetration. The primary frizz-blocking and hold agent. Panthenol (Provitamin B5) — adds elasticity and shine to the curl; keeps curls feeling soft rather than stiff through the hold. Extreme Bounce Factor — three-dimensional resin structure for a defined, elastic curl result. How To Use Apply a small amount to damp hair before styling. Scrunch from ends to roots or rake through to distribute evenly. Diffuse or air-dry. Can be layered under the Curl Moisturizing Mousse for added volume and definition. Frequently Asked Questions Is the Curl Building Serum a leave-in?Yes — it is applied to damp hair and not rinsed out. Do not rinse. What curl types is it best for?Wavy (2A–2C) to curly (3A–3C) hair. For coily hair (4A+), it can work well as a base layer under a cream or the Curl Gel Oil. Can I layer it with the Curl Mousse?Yes — apply the Serum first to damp hair for definition and frizz resistance, then layer the Curl Moisturizing Mousse on top for added volume and body. Will it make curls crunchy?No — the Panthenol and Extreme Bounce Factor keep curls elastic and bouncy rather than stiff.
