Inclusion criteria

  • Healthy volunteers male patients.
  • Aged 18 to 65 years.

  • Patients without a psychiatric diagnosis and who behave appropriately during the interview,
  • Signs of good hygiene and that have the ability to keep the areas undergoing treatment clean until they heal,
  • Patients who understand and speak Portuguese,
  • Patients with realistic expectations regarding the final benefits of treatment,
  • Needle phobia,
  • Independent patient, eliminating the need for tutoring or legal representative,
  • Absence of chronic viral diseases, for example , or ,
  • Absence of other skin diseases, for example lichen planus, psoriasis, Crohn's disease or ulcerative colitis,
  • Absence of , for example: lymphoma, transplant therapy, chronic use, Wiskott-Aldrich Syndrome or uncontrolled ,
  • Patients/participants with previously known allergies or those detected during the interventions (anesthetics, topical antibiotics or other medications used in the trials),
  • Absence of cardiovascular disease (e.g. previous myocardial infarction), absence of coagulopathy or use of anticoagulants, absence of neurological disease (e.g. stroke, cerebral ischemia), absence of renal, hepatic or endocrine disease (e.g. example, diabetes).
  • Patient/participant with medical conditions not mentioned, which in the investigator's view, prohibit participation in the study.

Exclusion criteria

Exclusion Criteria:

  • Detection during the test of allergy to the medicines used (anesthetics, topical antibiotics or other medicines used in the tests),
  • Breach of protocol, inappropriate conduct that compromises participant safety or interferes with the interpretation of study results,
  • Any illness or condition, which in the judgment of the investigators, interferes with the participant's ability to complete or terminate the investigation.
Terms in these criteria, in plain language(8)

Underlined terms in the criteria open these too. Explained by clinicaltrials.gg, not part of the registry record. The study team decides who can take part.

HIV

The human immunodeficiency virus, which weakens the immune system.

Many studies now accept people whose HIV is controlled on treatment, judged by the viral load and the CD4 count. Check the limits this study sets.

Hepatitis B tests

Hepatitis B is a virus that infects the liver. These are separate tests: HBsAg positive usually means a current infection (a recent vaccination can briefly cause it too); total anti-HBc (HBcAb) positive means an infection now or in the past; HBV DNA measures how much virus is in the blood.

Some studies accept a past infection if HBV DNA is undetectable, sometimes with antiviral medicine during the study. Check what this study allows.

Hepatitis C tests

Hepatitis C is a virus that infects the liver. An HCV antibody test can stay positive after an infection has cleared (and is occasionally positive without one); an HCV RNA test shows whether the virus is there now.

After treatment, hepatitis C counts as cured when HCV RNA is still undetectable 12 weeks or more after the treatment ended. Studies often accept people cured this way.

Immunosuppression

A weakened immune system. It can come from an illness, such as HIV or some blood cancers, or from medicines that turn the immune system down, for example after an organ transplant or for an autoimmune disease; steroids at higher doses count.

Read whether the line is about a condition or about medicines, and which medicines and doses it means.

Corticosteroids (steroids)

Anti-inflammatory medicines such as prednisone, prednisolone and dexamethasone — not the anabolic steroids used for muscle.

Studies differ in what they allow: check which steroid medicines, routes (tablets, injections, creams, inhalers, eye drops) and doses this study accepts.

Cancer (malignancy)

Malignancy means cancer. Criteria about another or earlier malignancy ask whether you have had a different cancer, usually within a set number of years.

Some are commonly allowed, such as treated skin cancers other than melanoma and early cancers removed completely — check the exceptions this study lists.

Clinically significant

Judged by the study doctor to matter for your health or for the study. It is a doctor’s decision, so ask the study team if you are unsure whether something counts.

Informed consent

Before you join, the study team explains what taking part involves — its purpose, what happens, the risks and possible benefits — and answers your questions, so you can decide freely. Consent is usually recorded on a form (the informed consent form, ICF) signed by you or, where the law allows, by someone legally authorised to decide for you.

You can keep asking questions during the study, you are told of new information that matters, and you can choose to leave at any time.

What researchers measure

Primary outcomes

  1. HAIR DENSITY

    analysis of hair density (number of follicles) per square centimeter using Trichoscale software (fotofinder) and clinical photographs.

    Time frame: 1 year

  2. HAIR THICKNESS

    measurement of the thickness of hair shafts using Trichoscale software (fotofinder)

    Time frame: 1 year

Secondary outcomes

  1. Sexual effects

    Assessment of sexual adverse effects (sexual impotence or decreased libido) through Likert questionnaire: The answer will be dichotomous, did you feel any sexual effects (impotence or decreased libido during your treatment? Yes or no?

    Time frame: 1 year
