The foundation of Keracol Limited and our products is sustainability with performance. We develop products that achieve high performance are safe and are sustainable.

To do this we utilise the fantastic array of chemistry that nature provides. We believe we can develop a new generation of products through our understanding of natural products, methods to extract and purify them in the cleanest way, and use their functionality to achieve performance. We combine high-end physical science with innovative consumer product applications. Keracol develops novel approaches to the extraction of active molecules from plant sources for existing and novel applications. Our extracts are effectively applied in cosmetic products for hair coloration, hair care and skin care; as food colorants and food ingredients; and in nutraceutical applications.

Keracol Limited is a spin-out company from The University of Leeds. Our expertise spans organic chemistry, colour chemistry, polymer and biopolymer chemistry, extraction technology, coloration technology, hair dyes, formulation science and natural products chemistry.


Dr. Craft’s Natural Purple Berry Brightening Serum formula actively neutralises yellow and brassy tones in blonde, silver and grey hair. Each treatment results in healthy, nourished and vibrant looking hair. Unlike “purple shampoos”, our serum uses 100% natural pigments, rather than synthetic dyes, to treat hair with brassy overtones!

Using groundbreaking science, we’ve extracted the skins from British blackcurrants and transformed them into natural and sustainable beauty! This patented technology uses blackcurrant skins, which contain high concentrations of natural pigments called anthocyanins. These give the berries their intense colour and counteract the brassy tones in your hair.

Scented with Bergamot, Eucalyptus, Spearmint, Tarragon and Lemon essential oils. 100% free from cruelty, SLS, silicone, synthetic dyes and fragrance.
