# Naturally Purple Hair Serums Dr. Craft's Berry Brightening Serum Reuses Beverage Industry Waste By Laura McQuarrie | Published 2019-07-11 | Eco Source: Trend Hunter, https://www.trendhunter.com/trends/berry-brightening-serum References: [cosmeticsbusiness](https://www.cosmeticsbusiness.com/news/article_page/How_beauty_brands_are_transforming_trash_into_treasure/146348) & [drcraft](https://drcraft.co.uk/products/dr-craft-s-natural-purple-berry-brightening-serum) Unlike many [color-correcting purple shampoos](https://www.trendhunter.com/trends/shampoo-for-brilliant-color) on the market that contain synthetic dyes, Dr. Craft's Natural Purple Berry Brightening Serum is made with 100% natural pigments from British blackcurrants. The berries that are used in the brand's product are sustainably sourced from leftover by-products from the manufacture of the blackcurrant-based beverage Ribena. According to Dr. Craft's, "This patented technology uses blackcurrant skins, which contain high concentrations of natural pigments called anthocyanins. These give the berries their intense color and counteract the brassy tones in your hair." For best results, the brand recommends applying the product to damp hair and allowing it to sit for a few minutes before rinsing. The [vibrant purple hair serum](https://www.trendhunter.com/trends/h90-hydroxytyrosol-hair-oil-serum) is cruelty-free and free from undesirable ingredients, including synthetic fragrance, and only boasts an alluring natural scent from bergamot, eucalyptus, lemon, spearmint and tarragon. ## Trend Insights (Trend Hunter) - Score: 4.3/10 - Popularity: 46% | Activity: 76% | Freshness: 8% - Audience gender: 50% men, 50% women - Primary generations: Millennial - Top markets: North America ## Categories [Trend Hunter](https://www.trendhunter.com/trends) > [Eco](https://www.trendhunter.com/eco) ## Key Themes ### Key Themes Behind This Trend - **Natural Hair Products:** Dr. Craft's Natural Purple Berry Brightening Serum showcases the trend of using 100% natural pigments in hair care products. - **Sustainable Sourcing:** The brand's use of leftover by-products from the Ribena manufacture demonstrates the trend of utilizing waste materials in product development. - **Color Correcting Alternatives:** Dr. Craft's Natural Purple Berry Brightening Serum provides a natural, synthetic dye-free alternative to traditional purple shampoos. ### Where This Applies - **Hair Care:** The hair care industry can explore the opportunity to develop more natural and sustainable hair products, such as serums made with natural pigments. - **Beverage:** The beverage industry can consider finding innovative ways to repurpose by-products and waste materials from their production processes. - **Fragrance:** The fragrance industry can identify opportunities to create natural-scented products that enhance the overall sensory experience without the use of synthetic fragrances. ## Related on Trend Hunter - [Tone-Correcting Hair Oils](https://www.trendhunter.com/trends/moroccanoil-treatment-purple.md) - [Color-Correcting Tooth Serums](https://www.trendhunter.com/trends/v34-colour-corrector-serum.md) - [Nourishing Hair-Coloring Masks](https://www.trendhunter.com/trends/overtone-purple.md) - [Naturally Derived Purple Toothpastes](https://www.trendhunter.com/trends/purple-toothpaste.md) - [Purple Oral Serums](https://www.trendhunter.com/trends/purple-serum.md) - [Color-Friendly Shampoo Formulations](https://www.trendhunter.com/trends/shampoo-for-brilliant-color.md) - [Teeth-Whitening Serums](https://www.trendhunter.com/trends/ultra-violet-colour-corrector.md) - [Purple Teeth Whitening Strips](https://www.trendhunter.com/trends/peroxidefree-purple-strips.md) - [Specific Haircare Lines](https://www.trendhunter.com/trends/silverist-haircare.md)
