When properly cared for, a horn comb can last many years, and even up to a lifetime. Like our hair, a horn comb is made of keratin. If left untreated, a horn comb can be prone to breakage.
Some people advise rubbing a bit of natural oil on the comb once or twice a year. Lanolin, jojoba oil, coconut oil, almond oil, olive oil, or sunflower oil all work. You can even rub a thin layer of Zeus Beard Oil on the comb, as our beard oils contain grape seed oil, argan oil, and safflower seed oil. If there is excess oil on the comb, just remove it with a clean cloth or a cotton ball.
But my experience is: regular COMBING will keep them happily oiled with your natural HAIR oils. I never rubbing oil on my horn comb, and my horn comb remains perfect condition after being used for over 20 years.
Boar bristle beard brushes are so good at catching dirt and debris from your hair that themselves need a good too.
To keep your horn comb clean, simply rinse it with water and let it dry on a cloth. Be careful NOT to submerge a horn comb and let it sit in the water for too long. This will warp the shape and make the comb brittle.
As a general rule, keep your horn comb away from wet surfaces.
Avoid high temperature, bend, drop and moisture.
It can be washed by cold water and dry it with towel afterwards to prevent shape changing.
In case the shape changes due to too much moisture, the shape can be recovered by heating it with a HAIR dryer and pressed with heavy books or something else heavy.
