Glossary Infection

Infection refers to the invasion and multiplication of pathogenic microorganisms, such as bacteria, viruses, or fungi, within the body, which can lead to inflammation and tissue damage. In the context of hair loss, infections of the scalp, such as fungal infections (e.g., tinea capitis) or bacterial infections, can disrupt the normal hair growth cycle and lead to conditions like alopecia or hair thinning. Key distinguishing characteristics of infections include symptoms such as redness, swelling, pain, and sometimes pus formation, which can help differentiate them from other causes of hair loss. Prompt diagnosis and treatment are essential to prevent permanent hair loss associated with scalp infections.

learn Scalp Micropigmentation

Is there a risk of infection with scalp micropigmentation? Any skin puncture can become infected, and the risk depends on sterile equipment, uncontaminated ink and aftercare. See a doctor for spreading redness, pus or fever.

learn Exosomes

Are exosomes applied as a serum, an injection, or combined with other hair treatments? Clinics offer exosomes as scalp injections, as serums applied after microneedling, or combined with PRP. No exosome product is FDA-approved, and no reliable evidence shows that any of these methods works.

learn Hydrocortisone

Can hydrocortisone be used together with other treatments like minoxidil or steroid injections? If minoxidil solution irritates the scalp, the cause may be irritation, seborrhoeic dermatitis or an allergy to an ingredient, so it is worth having a doctor or pharmacist look before adding a steroid. No verified trial tests hydrocortisone alongside minoxidil or corticosteroid injections, and prolonged scalp use risks skin thinning.

learn Verteporfin

Is Verteporfin used as a topical treatment, injection, or oral medication for hair loss? Verteporfin is an intravenous drug approved only for an eye condition; it is not approved for hair loss in any form. In the few published hair reports it was injected into the scalp alongside surgical wounding — unverified case reports of one and two patients, not trial evidence.

learn Hair Transplant

What are the risks and side effects of a hair transplant? Reported risks include swelling, redness, folliculitis, numbness, infection, scarring and temporary shock loss; less often skin necrosis, poor graft growth or over-harvesting of the donor area.
