Castor Oil Esters (Proshine)
The Science of Seriously Shiny Hair
Shine isn't just cosmetic. It's actually a sign of health. When a hair cuticle lies flat and smooth, light reflects evenly off it, creating that glossy, vibrant look. When it's lifted or damaged by heat, chemicals, or UV exposure, light scatters instead of reflecting, and the result is dull, flat hair.
What It Is
A 100% plant-based ester derived from castor oil, developed under Green Chemistry principles. Zero synthetic silicones. 100% biodegradable.
How It Works
ProShine® binds directly to keratin proteins inside the hair fiber, forming a uniform molecular coating with a high refractive index. Engineered to reflect light with intensity and consistency across every strand.
What the Science Shows
ProShine® was clinically tested across virgin, bleached, and color-treated hair, and the results speak clearly:
- 184% more shine on natural hair vs. placebo
- 428% more shine on bleached hair vs. placebo
- 127% shinier bleached hair vs. untreated strands
- 42% shinier color-treated hair vs. untreated strands
- Enhances the vibrancy of dyed hair, helping color look fresher for longer
These results hold across all hair types and textures, whether your hair is natural, lifted, or chemically treated.
Clean Credentials
ProShine® is derived entirely from castor, a renewable plant source, and produced under Green Chemistry guidelines. It's 100% biodegradable, contains zero synthetic silicones, and delivers real optical performance without any of the buildup or residue that traditional shine ingredients leave behind.
Brilliant hair. Clean formula. No compromise.
