Hair Carboxytherapy: What to Know

A trained medical professional injects carbon dioxide into selected scalp areas using a fine needle. The procedure is intended to alter local blood flow and tissue signalling, but the result depends on the cause and pattern of hair loss. It should not be treated as a substitute for identifying inflammation, infection, scarring, or a medical trigger.

Temporary stinging, pressure, redness, swelling, bruising, or tenderness can occur at injection sites. Suitability depends on your health, medicines, scalp condition, and the diagnosis being treated. Ask which product, equipment, practitioner credentials, and aftercare plan will be used.

Bring a list of medicines, allergies, bleeding problems, scalp conditions, and previous procedures to the consultation. Ask what improvement is realistic, how progress will be measured, and whether another treatment is more appropriate. Follow the clinic’s instructions about washing, exercise, heat, and styling after treatment; do not inject or apply unapproved products to the scalp yourself.

Contact the treating clinic for worsening pain, increasing swelling, persistent bleeding, drainage, fever, or spreading redness after injections. Seek urgent care for breathing difficulty, facial swelling, fainting, or other signs of a severe reaction. If hair loss is sudden, patchy, scarring, or accompanied by scale and pain, obtain a diagnostic dermatology assessment before pursuing an aesthetic procedure.

What is causing my hair loss, and how does this treatment address that cause? Who will perform the injections? What side effects and aftercare should I expect, and how will we judge whether to continue?
