Microneedling treatment for Hair Loss
Microneedling is a cosmetic treatment that addresses various effects of aging. It’s also nicknamed skin needling because of its effects on increasing collagen production in the skin.
It involves the use of a Derma pen with small needles that causes minor skin injuries. This then trigger a healing response and production of collagen.
While used as an anti-aging skin treatment, microneedling may also be a method of treatment for hair loss. There’s even evidence that it can help hereditary hair loss, also known as alopecia.
The same process of creating wounds in the skin is also thought to regenerate the health of the hair follicles. It’s thought that this can result in new hair growth, or perhaps thicken thinning hair.
Microneedling for hair loss benefits
Microneedling first gained its reputation as a scar treatment during the 1990s. Since then, it’s been studied as a potential alternative for thinning hair and hereditary hair loss.
Aside from collagen production in the skin, it’s thought that microneedling can also help induce stem cells in the scalp that lead to hair growth.
Microneedling may also promote the absorption of hair growth products, such as minoxidil (Regaine). Another study explored the potential benefits of microneedling when used with corticosteroids to reduce hair follicle inflammation from alopecia areata.
How it works
During microneedling, the Dermapen oscillates at various needles depths, ranging between 0.25 and 3 millimeters.
Unlike other treatments that target your skin’s surface, the needles used in the dermapen extend to the middle layer of skin. As these microinjuries heal, your skin produces more collagen and fibers. It also helps to strengthen the hair follicles.
A topical anesthetic is applied to your scalp about 20 minutes prior to treatment. This helps to reduce any pain you may feel.
The actual procedure time can vary based on treatment area, but may take as little as 30 minutes. After the scalp microneedling is completed, a soothing balm or serum is applied to the area to alleviate inflammation and discomfort.
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 Nurse 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 or are on any 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 and 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.
