What makes Onesta's Create Finish a green product? Our can is made with 30% post consumer steel and is 100% recyclable. And, we use a 100% natural fragrance. Most aerosols on the market today use synthetic fragrances, which can be comprised of up to 200 individual chemicals to make one perfume, including trace amounts of formaldehyde. One of the biggest health concerns with aerosols is inhaling the small molecules of synthetic fragrance. This natural fragrance makes this aerosol safe for hairdressers and clients alike. Create Finish is the safer alternative with great performance. Provides volume, flexibility, and long-lasting hold. Humidity-resistant.
