Carboxytherapy for Hair Loss: How CO₂ Can Help Revive Your Scalp
Carboxytherapy for Hair Loss: How CO₂ Can Help Revive Your Scalp
Hair loss is more than a cosmetic concern—it can deeply affect self-esteem and confidence. Whether you’re dealing with patchy bald spots (Alopecia Areata) or gradual thinning over time (Androgenetic Alopecia), finding a treatment that actually works can feel like chasing miracles. But here’s some good news: Carboxytherapy is emerging as a promising and natural option for both types of hair loss.
Let’s break it down in a simple way.
1. What Is Carboxytherapy for the Scalp?
Carboxytherapy is a treatment where small amounts of sterile carbon dioxide gas (CO₂) are injected into the skin or scalp using a tiny needle. Though it may sound high-tech, this technique actually has its roots in 1930s France, where CO₂-rich spa waters were used to help heal wounds. Later, doctors began injecting CO₂ under the skin to treat poor circulation and skin aging.
Today, this method is also used in aesthetic and hair clinics to boost blood flow, repair damaged tissues, and even promote new hair growth.
2. How Does It Work for Hair Loss?
When CO₂ is introduced under your scalp, it tricks your body into thinking there’s a lack of oxygen in that area. This triggers what’s called the Bohr effect—a natural response that widens blood vessels and sends more oxygen and nutrients to the area.
The result? Improved blood flow to hair follicles, which helps “wake them up” and support healthy regrowth.
On a deeper level, carboxytherapy:
-
Reopens tiny capillaries that may have closed
-
Stimulates collagen production and skin healing
-
Helps create new blood vessels (neovascularization)
-
May also reduce inflammation—an important benefit for autoimmune-related hair loss like alopecia areata
3. Who Can Benefit From This Treatment?
Carboxytherapy can be helpful for:
Alopecia Areata (AA) – the autoimmune type that causes patchy hair loss
Androgenetic Alopecia (AGA) – also known as male/female pattern baldness
Real clients results
People who want a natural, non-surgical approach, hair transplant preparation.
Those not responding well to other treatments like minoxidil or PRP
Clients looking to enhance results from other therapies (e.g. microneedling, mesotherapy)
4. What Does the Research Say?
In a study from Egypt involving 80 patients, those treated with carboxytherapy showed clear signs of improvement:
-
Patients with Alopecia Areata had new regrowth in bald patches, reduced signs of follicle damage, and better SALT scores (a way to measure severity).
-
Those with Androgenetic Alopecia experienced increased hair density and healthier scalp appearance using digital dermoscopy.
-
The effects lasted well after treatment, though maintenance sessions may be needed.
Compared to placebo groups (who received water injections), those who had carboxytherapy did significantly better—proving the treatment isn’t just placebo, it really works.
5. Is It Safe? Are There Any Risks?
Yes—carboxytherapy is considered safe and minimally invasive when performed by trained professionals. Since CO₂ is naturally present in our bodies, there's virtually no risk of allergic reaction.
However, it’s not for everyone. Contraindications include:
-
Severe anemia, heart failure, or uncontrolled blood pressure
-
Pregnancy or breastfeeding
-
Skin infections or autoimmune flare-ups
-
Unrealistic expectations (it takes time!)
Mild side effects may include slight discomfort, redness, swelling, or a crackling sensation at the injection site, but these resolve quickly. Most people describe it as a bit of “pressure and warmth” during treatment.
6. How Many Sessions Do You Need?
Hair regrowth doesn’t happen overnight. Most studies suggest:
-
6–10 sessions, done weekly ( ideal scenario 2-3 per week for 2-3 first weeks, and than just to maintain next few months).
-
Results start appearing after a few sessions, with best outcomes after consistent treatment
-
Maintenance sessions every few months can help prolong the results
Younger clients and those in early stages of hair loss tend to respond faster and better.
Final Thoughts
If you're dealing with stubborn hair loss and want a science-backed, natural treatment, carboxytherapy may be the game changer you’ve been looking for. It works by improving scalp circulation and supporting hair regrowth—especially when combined with other professional trichological care.
Whether you're seeing early thinning or facing patchy hair loss, carboxytherapy offers a safe, gentle way to bring life back to your scalp.
