Mesotherapy is a non-surgical treatment for the hair loss. It involves injecting nutrients into the scalp to boost hair growth. Many people turn to this method when they see signs of thinning or bald spots.

Mesotherapy for hair is generally safe, but it can cause side effects like redness, itching, swelling, bruising, or mild pain on the injection site.

Some people may experience temporary hair shedding, dizziness, or, in rare cases, allergic reactions and infections. Most side effects are mild and go away within a few days when proper aftercare is followed.

In this post, we’ll explore the possible side effects of mesotherapy for hair, so you know what to expect and how to deal with them.

Mesotherapy for Hair: A Simple Guide to Side Effects

Mesotherapy is a growing trend for people dealing with hair thinning or hair loss. It works by injecting a mix of vitamins, amino acid, enzymes, and other nutrients directly into the scalp. But like all cosmetic treatments, mesotherapy isn’t without risks. While many experience little to no discomfort, side effects can still happen.

But before you jump in, it’s smart to understand the side effects. While most people do well, some may notice mild or even serious reactions. This post breaks everything down in plain words.

What Happens During Mesotherapy?

Let’s start with how the process actually works. Mesotherapy delivers vitamins and nutrients straight to your scalp. Here’s what that looks like:

  • Small Injections on the Scalp: The doctor uses tiny needles to inject solutions into the skin. These needles go just under the surface—no deep poking! The goal is to feed your hair roots with ingredients that help them grow.
  • What’s Inside the Solution: The mix may contain vitamins like biotin, amino acids, or herbal extracts. Some doctors add medications or growth factors too. Every provider may use a slightly different blend.
  • Helps With Blood Flow: The treatment boosts circulation in your scalp. Better blood flow gives better nutrient delivery to hair follicles.
  • Treatment Schedule: Most people need multiple sessions, usually once a week. After a few weeks, follow-ups may be monthly. Results usually take a couple of months to show.

Mesotherapy isn’t a one-time fix, but a steady care plan.

Common Side Effects of Mesotherapy: Usually Mild and Temporary

Mesotherapy is considered minimally invasive. That means side effects are usually mild and go away quickly. Let’s take a closer look at what you might experience:

  • Redness or Swelling on the Injection Site: After treatment, your scalp may look red or feel slightly swollen. This is a normal response as your skin reacts to the needle and solution. The redness typically fades within a few hours or by the next day.
  • Itchy Scalp: You may feel some itching as your scalp starts to heal. This can happen from the tiny punctures or from how your skin reacts to the ingredients. Avoid too much scratching, as this can cause irritation or infection.
  • Mild Pain or Discomfort: You might feel a sting during the injections. Afterward, the treated area may feel sore, like a small bruise. Most people compare it to the feeling after getting a shot, uncomfortable but bearable.
  • Bruising: Small bruises may appear where the needle went in. These bruises are usually harmless and disappear within a few days. You can apply a cold compress to help the healing process.
  • Tiny Bumps: It’s common to see small, raised bumps on the scalp after the session. These are formed by the fluid that was injected. They usually flatten out in 24 to 48 hours as your skin absorbs the ingredients.
  • Dryness or Flakiness: Your scalp might peel slightly or feel dry after mesotherapy. Using a gentle, hydrating shampoo or scalp moisturizer can help.

Less Common but Possible Reactions of Mesotherapy

Rare reactions can happen too. These are less common but more serious. Even though these aren’t common, it’s important to be aware. That way, you can act fast if something feels off. Here’s what to look out for:

Bleeding and Scabbing: Rare But Possible

Though not common, some people may notice a bit of bleeding during or after the treatment. This can lead to tiny scabs or crusts on the scalp.

  • Avoid Scratching or Picking: Let the scabs heal on their own. Picking can lead to infections or even hair damage.
  • Keep the Scalp Clean & Dry: Avoid washing your hair or sweating for at least 24 hours. This helps prevent germs from getting into the skin.
  • Use a Mild Shampoo: Wait at least 48 hours before using shampoo. Choose a sulfate-free product that won’t irritate your scalp.

If scabs don’t heal within 5 to 7 days, contact your provider for advice.

Headaches and Dizziness: Short-Term Effects

Some people report feeling lightheaded or having a mild headache after the procedure. This usually happens because of the needles or anxiety during the session.

  • Rest After the Session: Give yourself 30 to 60 minutes to relax and recover. It helps your body settle after the procedure.
  • Stay Hydrate: Try todrink plenty of water before and after the session. It helps regulate blood pressure and keeps dizziness at bay.
  • Avoid Driving: If you feel woozy, don’t drive or operate machinery. Ask someone to accompany you if it’s your first session.

Allergic Reactions: Not Very Common, But Serious

Mesotherapy solutions contain several ingredients. In rare cases, your body may react badly to one of them.

  • Rash or Hives: Red, itchy patches on your skin can signal an allergic reaction. It may appear within minutes or hours of treatment.
  • Severe Itching: If the itching becomes intense or spreads, seek medical help. It could be a sign that your body is reacting negatively to the injected solution.
  • Swelling of the Face or Lips:This is more serious and could point to a strong allergic response. Swelling in the throat or face should be treated as an emergency.
  • Trouble Breathing: If you struggle to breathe after treatment, call emergency services immediately. This could be anaphylaxis, a life-threatening reaction.

Infection Risk: Keep Everything Clean

Any time a needle punctures the skin, there’s a chance of infection. Good hygiene is key to preventing this.

  • Go to a Licensed Clinic: Only choose qualified and experienced professionals. They should use clean, sterile tools every time.
  • Make Sure Tools Are Sterilized: Don’t hesitate to ask how the equipment is cleaned. Reputable clinics will be happy to explain their safety procedures.
  • Don’t Touch or Rub Your Scalp: After the treatment, your scalp is sensitive. Keep your hands off to reduce the risk of introducing bacteria. Signs of infection include pain, swelling, heat, or pus at the injection site.

Hair Shedding After Treatment: Temporary Shock

It can be scary to see more hair falling out after you start mesotherapy. But it doesn’t mean the treatment failed.

  • Happens as Weak Hairs Fall Out: This is known as "shock shedding." The old, weak hairs fall so stronger ones can grow in their place.
  • Should Stop Within 2 to 4 Weeks: The shedding doesn’t last long. If it continues beyond a month, check with your doctor.
  • Hair Growth Often Improves Later: Many people see new, thicker hair come in around 6 to 12 weeks after the session.
  • Mental Impact: Worry, Stress, or Anxiety: If you're not seeing results right away, you may feel frustrated or anxious.
  • Talk to Your Doctor: Ask what results are realistic. Knowing what to expect cmay help reduce worry.
  • Be Patient: Hair takes time to grow. Most people need several sessions to see big changes.
  • Avoid Comparing with Others: Everyone’s scalp and hair health are different. Focus on your journey.

Frequently Asked Questions

Can mesotherapy for hair interact with other scalp treatments or medications?

Yes, mesotherapy can interact with other topical or oral treatments, especially those used for hair loss, like minoxidil or finasteride. It's important to inform your provider about any medications, supplements, or treatments you're currently using to avoid potential skin irritation or reduced effectiveness.

How long do the results of hair mesotherapy last, and will I need maintenance treatments?

Results from mesotherapy vary, but many people see improvement for several months after completing their initial sessions.
