Hair Smoothing Brush
A one-of-its-kind anti-frizz smoothing brush designed to tame frizz and improve everyday hair smoothness - without heat or chemicals.
Frizz control & smooth hair without heat damage


DOUBLET by Enagen Bio is a one-of-its-kind anti-frizz smoothing brush engineered to tame frizz, smooth the hair surface, and improve manageability through intelligent mechanical design, without relying on heat or chemical treatments.
Crafted with 100% natural boar bristles, DOUBLET works by gently encouraging the hair cuticle to lie flat. This helps reduce surface roughness that leads to frizz, flyaways, and uneven texture, resulting in hair that looks smoother, more polished, and easier to manage over time.
Its dual-sided design allows the hair to be guided and controlled from both sides simultaneously, helping improve alignment and smoothness during brushing. With consistent use, hair may appear straighter as a natural outcome of reduced frizz and better cuticle behaviour, without forcing or damaging the hair fibre.
Unlike heat-based styling tools, DOUBLET works with the hair's natural structure, supporting hair integrity and everyday hair health.
DOUBLET is ideal for those looking for:
• Reduced frizz without heat styling
• Smoother-looking, more manageable hair
• Enhanced natural shine and softness
• A gentle, scalp-respecting brushing experience
Suitable for: Fine to medium, straight to slightly wavy hair types
Not recommended for: Curly or coily hair types
Best used as: A daily part of a clean, modern haircare routine
✅ Frizz Control: Helps smooth hair by gently encouraging the cuticle to lie flat - no heat, no chemical stress.
✅ Cuticle-Friendly Smoothing: Boar bristles mimic the keratin structure of human hair, allowing smoother glide and reduced friction.
✅ Natural Conditioning & Shine: Distributes natural scalp oils evenly along the hair shaft for softness and shine - without silicones.
✅ Reduced Breakage: Flexible bristles move in harmony with the hair fibre, minimising friction-related stress during brushing.
✅ Dual-Sided Hair Guidance - Simultaneous contact from both sides helps tame flyaways and improve overall hair texture.
Material Information
DOUBLET is engineered with 100% natural boar bristles, a material long recognised for its gentle yet effective interaction with hair.
Boar bristles contain naturally occurring keratin proteins and have a surface structure similar to human hair, enabling smoother glide, better oil distribution, and reduced friction compared to synthetic alternatives.
Care Instructions
To maintain the performance and longevity of your DOUBLET brush:
Daily Use
• Use on dry hair only for optimal smoothing and oil distribution
• Start at mid-lengths and ends, then gently work towards the roots
Cleaning (Every 2–3 Weeks)
• Remove loose hair after each use
• Add a few drops of mild shampoo to lukewarm water
• Dip a soft cloth or bristle cleaner (do not soak the brush)
• Gently clean between bristles to remove oil and debris
• Air-dry with bristles facing down
👉 Avoid fully immersing the brush in water, as prolonged soaking may loosen bristles or damage the handle.
