Purchasing the right brush can solve and prevent more hair problems than you think. Getting the right brush is the KEY.
THREE components you need to know: Handle, Barrel and Bristles
HANDLES: come in many shapes and sizes. Larger Foam are for those who have difficulty holding a brush. Narrow Wood or Plastic handles can be difficult to grip and can create fatigue your hand quickly.
BARREL: size is important. How to judge the size for curling, you have to be able to rotate the brush 1 1/2 times minimum around the barrel to create a single curl. To smoothen hair barrel size is generally larger 70-80mm in diameter. Those of you with enough hair for 3 people can use an even larger diameter brush.
Composition of the Barrel: Metal usually ceramic, copper or tourmaline can create more damage because they heat up and stay HOT longer but do not COOL down causing more damage to the hair.
Vented are ultra light BUT when you have wet hair over the vented barrel brush the air from the dryer doesn't really penetrate through it its' impossible think about it.
Wood are designed to hold bristles and are not really efficient for HEATING or COOLING.
BRISTLES; Boar, Nylon mix, Metal or Wood .This is the #1 most important feature of your brush. Golden Rule: The bristle should be Slightly firmer than your hair but not so firm as to break it. Fine hair needs to have a boar or nylon mix but the bristles must be FLEXIBLE. Coarse hair remember the person with enough hair for 3 people also wiry or textured. The key words to look for are Porcupine or Natural Boar, Sanglier with nylon which tends to be stronger and firmer for penetration and control. The nylon in this brush should be really firm and the tips not scratchy. Pease note: natural boar bristle brushes on their own generally do not work for this hair type unless they are of an extremely high quality and thick diameter( you all know the brushes we are talking about).
General rule of thumb run your hand over the boar brush to feel the resistance of the pad on your hand and ask yourself is this firmer than my hair or is it too soft or too firm? Run your hand over the rows of bristles to feel the character of the bristles if you can't touch it don't buy it!
Wood Bristles are generally used on a paddle type brush but be careful if they get wet the wood can splinter and actually tear your hair.
Metal bristles on a hair brush why?.... There is little flexibility which is really only in the pad. What is flexible about metal.
Bristle Tips: when purchasing a brush look closely at the tips of the bristles if they are flat like a toothbrush they will not penetrate and will be hard to control. Staggered or irregular bristles will offer you more control as the hair will actually fall into the bristles for more tension.
Bristle Pattern: some are straight rowed and hair will not penetrate well and definitely don't work on thick hair.
Corkscrew Pattern: will create a range for blow drying from Mega Volume to a Sleek Smooth Finish Now putting YOU in control of your hair.
Density of Bristle : too much bristle doesn't grip,likewise too little doesn't grip.
Vented brushes are better for textured hair the bristles are wide enough to get through the hair without creating damage or frizz. They do not dry the hair faster.
All said and done when your hair is wet it stretches 50%, and when its dry only 20% of its length. It's the stretching that allows hair to SET that's why wet styling stronger then dry styling.
