Glossary Infections

invasion of harmful microorganisms causing tissue damage and illness

Infections occur when harmful microorganisms such as bacteria, viruses, fungi, or parasites invade the body, multiply, and cause damage to tissues. These pathogens can trigger the immune system to respond, leading to symptoms like fever, inflammation, and other signs of illness. Understanding the type and source of infection is crucial for effective treatment and prevention.

learn Scalp Micropigmentation

Is there a risk of infection with scalp micropigmentation? Scalp micropigmentation has a risk of infection, but proper aftercare minimizes it.

learn Botox

What’s the science behind Botox injections for androgenetic alopecia? Small published studies and a 2025 meta-analysis report hair-count gains from scalp botulinum toxin injections, but nearly all of them lack control groups, and reviewers of the same literature call the evidence low-quality; the treatment is off-label and not approved for hair loss anywhere.

learn Follistatin

Can follistatin be applied topically, or is it only effective through injections or systemic use? Follistatin is not effective when applied topically and requires injections or systemic use.

learn Vitamin B12

Should Vitamin B12 be taken orally or by injection for hair loss treatment? Vitamin B12 can be taken orally or by injection if a deficiency exists.

learn Hydrocortisone

Can hydrocortisone be used together with other treatments like minoxidil or steroid injections? Clinicians do use a mild steroid cream to settle the scalp irritation minoxidil can cause, but no verified trial tests hydrocortisone added to minoxidil or to corticosteroid injections, and prolonged scalp use risks skin thinning — combining it is a decision to take with a prescriber.
