Pseudofolliculitis barbae (PFB), also known as barber’s itch, Foliculitis Barba Trematica, Rasar Bump, Beard’s pseudo-pseudo-Solopholiculitis and Shave Bump, is a medical term for continuous irritation due to shaving. Pseudofolliculitis barbae(PFB) was first described in 1956.
Causes
Pseudofolliculitis barbae (PFB) is most common on the face, but also where the hair is shaved or plucked on other parts of the body, especially in those areas where the hair is curly and the skin is sensitive, such as shaving. (More precisely calledPseudofolliculitis barbae (PFB)

After shaving hair, it starts moving back. Curly hair moves straight into the skin instead of the follicle, which causes swelling reaction. PFB skin may be itchy and red, and in some cases, it can look like chickens. These swollen papules or pustules can be made especially if the area gets infected.
This is especially problematic for those men who naturally rotate thick hair tightly or tightly. Curly hair increases the likelihood of PFB by a factor of 50. If the treatment is not done over time, then it can cause the kidney scarfing in the beard area.
Pseudofolliculitis barbae (PFB) can be further divided into two types of injection hair: transfollicular and extrafollicular. Extrafollicular hair is a hair which turns out from the coupe and the skin is reentered. Transfollicular hair does not come out of the follicle, but due to its naturally curly nature, the fluid builds up and comes back in the coupe that produces irritation.
A common polymorphism in the keratin gene (K 6 HF) is associated with PFB, which states that it can be a genetic risk factor. This sequence change leads to an amino acid replacement in the highly preserved helix initiation format of K6hf rod domain. Carriers of A12T polymorphism are six times more likely to develop PFB than homozygous people for wild type 6 HF sequence. It indicates that the 6 HF mutation weakens the partner layer separating the outer and outer root sheaths internally and enhances the chances of growing the hair of the beard. Read More
