Two Olivia Garden brushes with the same barrel size can behave completely differently, because the bristle is doing most of the work. Here is what each type in our range does.
Ion bristles (nylon with tourmaline or ionic treatment)
What they do: release negative ions that neutralise the static charge blow-drying builds up. Static is what makes fine hair fly away and frizzy hair puff.
Best for: fine hair, static-prone hair, anyone blow-drying in a dry Canadian winter. This is the default bristle in the NanoThermic and Ceramic + Ion lines and it is the safest choice if you are not sure.
Weakness: nylon does not polish the cuticle the way boar does, so you get less surface shine.
Boar bristle
What they do: natural boar is close in structure to hair, so it grips the cuticle, lays it flat and drags the scalp's own oils down the strand. That is where real shine comes from — not from product.
Best for: shine on a finished blowout, daily brushing on dry hair, smoothing coarse or unruly hair, and anyone with a dry mid-length and ends.
Weakness: boar alone has almost no penetration on thick or dense hair — it slides over the surface. And it is not vegan. On very oily hair, daily boar brushing will make the roots greasy faster.
In our range: the boar-bristle styling brushes, the EcoHair Bamboo boar-and-ion large barrels (54–76 mm), and the StyleUp ionic boar teasing brush.
Combo — boar and ion together
What they do: alternating tufts. The nylon ion pins get through the hair and give you tension; the shorter boar bristles polish the surface as the section passes.
Best for: the honest answer is most people. If you want one brush that both smooths and shines on medium to thick hair, this is it.
In our range: Ceramic + Ion Turbo Vent Combo (22, 34, 44 mm), the EcoHair Bamboo Combo Vent brushes (54, 57, 67, 76 mm), the Barber Wave Combo and the On The Go folding brush.
Memory-flex and ball-tip nylon
What they do: bristles engineered to bend out of the way under load and spring back, with rounded tips that will not scratch the scalp. They are designed to fail before your hair does.
Best for: wet hair, detangling, children, extensions, and any hair that is chemically compromised. Brushing wet hair is where most mechanical damage happens, and this is the bristle that reduces it.
In our range: the iDetangle line (separate versions for fine, medium and thick hair), the Detangler ball-tip brushes, the Divine tension-flex brushes and the mini detanglers.
Wide-set cone bristles
What they do: tapered cone-shaped bristles set far apart, so a curl clump passes through without being pulled straight.
Best for: curly and coily hair. This is the whole point of the CurlyHair line, which is sized by curl type rather than hair thickness.
Bamboo bodies: EcoHair and EcoCeramic
Bamboo is a body material, not a bristle. The EcoHair line pairs a renewable bamboo handle and barrel with boar-and-ion or ion bristles; the EcoCeramic line pairs bamboo with a ceramic thermal barrel and a firmer bristle for thick hair. Choose EcoHair for the sustainability with normal tension, EcoCeramic when you need to pull hard.
Quick decision
- Fine, static, flyaway hair → ion. NanoThermic or Ceramic + Ion.
- Dull hair you want shiny → boar, or combo if you also need tension.
- Thick, coarse, hard to control → combo, or EcoCeramic Firm.
- Wet hair and detangling → memory-flex or ball-tip. Never boar.
- Curly and coily → wide-set cone bristles, CurlyHair line.
- Vegan → ion and memory-flex nylon only; avoid boar and combo.
