  • Cork Handle Weighs 40% Less Than Wood — Your Arm Stays Relaxed from the First Section to the Last: Most round brushes share the same dense wooden handle; cork oak releases grip pressure as your palm warms instead of slipping; finish a full section-by-section blowout on fine to medium hair without switching hands or losing control; the lightness is something you feel in your shoulder before you think to notice it
  • Blonde Boar and Flexible Nylon Pins — Two Materials That Do Different Jobs in the Same Pass: Blonde boar bristles have a slightly open cuticle-like surface that picks up your hair's natural oils and redistributes them from root to tip; the flexible nylon pins sit between the boar rows, lifting at the root and maintaining even tension through the length; the two work in the same stroke — shine and volume are built together, not in separate steps; works best starting at about 75 percent dry
  • Won't Catch, Snap, or Drag Through Thinning Strands:Stiff bristles fight fine hair — every stroke pulls three ways at once and you hear the cost; the Soft-Tension blend flexes in the same direction your hair moves, releasing resistance before it becomes breakage; pulls through light tangles without yanking; the smooth-tip nylon pins never contact your scalp with pressure; if you have heard the snap before, you won't hear it with this brush
  • Built for Shoulder-Length-and-Down, Fine to Medium Hair — Here Is What a Section Actually Feels Like: Take a two-inch section, wrap it once around the 2.75 inch barrel, pull the dryer across; the hair doesn't bunch or resist — it rolls away from the brush with a slight give, the way a good blowout should feel; if your hair is very dense and coarse, a stiffer-bristle brush will grip your texture better; for color-treated and naturally straight to wavy lengths, this barrel size fits exactly
  • Nine Inches Tip to Base — Same Length as a Standard Blow Dryer, One Brush That Does More Than Morning Blowouts: Hand-finished cork handle and Blonde Boar and Nylon bristles arrive gift-boxed; use it for daily blowouts, then try wrapping dry sections for two-minute root-lift touch-ups on second-day hair; works on thinning, color-treated, and naturally straight to wavy lengths; TRENFI S3 is one of five brushes in the S Series — each matched to a different hair texture and result

This is the best brush I have ever owned. I have fine hair and it removes tangles without breaking my hair. I am not sure how this will work with thick hair, but works great for fine hair. Worth the price.

Would not recommend for super straight hair. I thought this brush was perfect. Very lightweight, easy to hold and handle. Loved the combination of boar's bristles and nylon bristles to help pick up and grip the hair. Unfortunately it just slid over my super straight hair without picking it up to roll. I think if your hair has some texture, this would be a perfect blow-out brush. But if your hair...

I'm giving it 4 stars because it is a very nice brush, but it doesn't work for my hair as the bristles are very, very, soft. When I searched for a brush, I was specifically searching for a salin grade hairbrush for 4C hair. This kinda just pushes my hair back and doesn't actually brush it. Can't send it back, because I already used it. If you have softer, fine, hair this might be better to use.

I love this hair brush. The quality is super nice and bristles don’t fall out of it when used. The handle is made of nice cork and make it easy to grip. This brush is very good for the price point and makes it easier when I blow dry or straighten my hair with it.

This brush is a great tool for those of us with unruly, frizz-prone hair. The brush head contains densely-packed bristles, unlike others I've ever used. I initially thought it was supposed to be a 100% boar bristle brush, but it didn't feel like the others I own. I then checked the description and found that the bristles are a dual-fiber mix, a carbon fiber core surrounded by boar bristles.The...

This boar bristle brush is so soft and gentle on the hair. It helps me to achieve great blowout hairstyles and it helps to leave the hair bouncy and soft. I have used it for several weeks on my hair and my daughter’s hair and I was able to achieve great hair styles. Works well on fine to more textured hair. Has a great grip to it while using creating comfort.
