Known by a few, the comb made of horn - also called 'bone comb' - is an excellent option opposite to plastic combs. Like the wooden combs, they also do not conduct static electricity of the hair (responsible for the known 'frizz').
In Fortaleza / CE, at the Feirinha of Beira-Mar Avenue, you can find them in the tent of Rosalia. Her tent is very close to a monument at the place - look at the yellow circle on the right. Contacts for previous orders can be made by e-mail email@example.com
The price is more expensive than ordinary combs - R$ 20.00 - but it pays off!
