Side effects of microneedling on the head
Microneedling itself can cause bruises, oozing from the wounds, and skin irritation. There’s also a risk that the wounds caused by the needles may scar.
The area may be red and inflamed for a few days following the procedure. According to the American Academy of Dermatology (AAD), most side effects diminish within five days after your treatment.
Speak with your doctor before you consider this treatment if you:
- have a history of acne, eczema, or open wounds
- have a condition that slows healing, such as diabetes
- are on blood thinners or other medications.
Microneedling also isn’t recommended for people who are pregnant.
Using microneedling before minoxidil can increase the absorption of the treatment. However, this can also increase the risk of side effects from the minoxidil, such as:
- burning
- itching
- inflammation
Your scalp may be more sensitive to the sun after treatment. Wearing sunscreen every day is recommended. A hat can also help protect your scalp when outdoors.
Another risk of microneedling on your head is the possibility of infection. While the needles are small, they’re still inflicting wounds.
You’ll need to follow your aftercare instructions carefully to prevent infection. This often involves keeping the area clean for a few days, as well as using antiseptics to ward off bacteria.
You may be at an increased risk for infection if you’re in poor overall health, or if you have a history of frequent infections.
