A cheap object that solves a specific problem: oil sitting at the roots while the ends stay dry. Boar bristles are close enough to hair in structure to carry that oil down the length instead of pushing through it. The visible effect is roots that look less greasy without washing more often, which is the opposite of what most people do about the problem and the reason the problem persists. It costs less than most shampoos and lasts years.
What it will not do
Not useful on very short hair, and it will not detangle thick or curly hair. That needs a wide tooth comb instead. It also does nothing about dandruff.
How to use it
On dry hair, once a day, from the scalp downwards. Thirty seconds is enough. Not on wet hair, because wet hair stretches and breaks.
Key ingredients
Natural boar bristle. The stiffness matters more than the brand or the handle.
