Microneedling for hair loss treatment
Microneedlingis a type of cosmetic treatment that addresses various effects of aging. It’s also nicknamed skin needling
because of its effects on increasing collagenproduction in the skin.
It involves the use of a skin roller with small needles that cause minor skin injuries.
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.
How it works
During microneedling, your doctor uses several needles, ranging between 0.25 and 3 millimeters long. They’re all contained in a handheld device. Also called a roller, the device is rolled along the treatment area, creating small injuries.
Unlike other treatments that target your skin’s surface, the needles used in the rollers 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 doctor will apply a topical anesthetic to your scalp about 45 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, the therapist will apply a soothing balm or serum to the area to alleviate inflammation and discomfort.
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.
