SCALP & HAIR REJUVINATION
Microneedling is a type of 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 skin roller with small needles that cause minor skin injuries.
While used as an anti-aging skin treatment, micro-needling 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.

During micro-needling, your doctor uses several needles, ranging between 0.25 and 3 milimeters 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 micro-injuries heal, your skin produces more collagen and fibers. It also helps to strengthen the hair follicles.
A therapist will apply a topical anaesthetic 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 micro-needling is completed, the therapist will apply a soothing balm or serum to the area to alleviate inflammation and discomfort.

Using micro-needling 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 micro-needling 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.
