Black piedra is a form of fungal infection that is rare and is also called trichomycosis nodosa black. Our company constituted by specialists from different disciplines, remains actively engaged in research and innovation on how to deal with black piedra, we are able to service and assist researchers throughout all the stages of their scientific research.
Overview of Black Piedra
Black piedra is caused by a fungus called Piedraia hortae which manifests in the form of small black nodules that can be found on the shaft of hair. Black piedra is believed to occur mostly in places with humid and subtropical temperatures including regions in South America, Central America, and parts of Asia. As for the hair follicles themselves, black piedra is known to cause nodule development which makes the hair strands more prone to breakage.
Symptoms of black piedra may include:
- Small, hard nodules on hair strands
- Dark brown or black color of the nodules
- Itching or irritation in the affected area
- Hair breakage or loss

Pathogenesis of Black Piedra
The hair cuticle and the hair shaft cortex should be integrated on the black piedra noduli which results from the fungus Piedraia hortae. Discussions on the primary mechanisms of causation as being proficient of hair shaft being attached and perhaps penetration more salient in pondering. Black piedra also has geography, hygiene, and climate as determining factors.
Therapeutics Development for Black Piedra
Topical antifungal agents
Topical antifungal agents ketoconazole and miconazole have almost always proven to be beneficial therapeutic agents for black piedra.
Oral antifungal drugs
Oral antifungals iatraconazole, and terbinafine are considered systemic therapy useful for people with extensive or recurrent infections.
