How to Use a Derma Roller on Your Scalp

Pick the size of your needle

When researching micro-needling and hair loss, the web suggests a needle of 1.5 millimeters as the most common length for treating hair loss. This size coordinates with the depth of the penetration, as your hair follicles sit between 1 to 2 millimeters deep within your dermis. This is the exact depth of penetration that is required. Another option is using shorter needles, but they might not be as effective.

Establish a good wash routine and sterilize the derma roller

An exfoliating shampoo brush along with a thorough lathering and rin9sing process will lift away all the dead skin and dirt present on the surface of one’s scalp. After washing, the derma roller including (the needles) need to be sanitized using rubbing alcohol.

Use a wide-tooth comb

Combing out all the tangles and knots is essential to allow the derma roller to cover all areas of the scalp.

Parting hair to allow unrestricted access

First, part your hair all the way to one side and roll. When this area is done, move to the next. Part your hair in sections to fully reach all areas of the scalp.

Use the derma roller horizontally

Work from side to side on each exposed portion of your scalp using a horizontal motion.

Maximize stimulation

Make sure you cover all areas of the scalp, go over each area several times before completing the treatment. Studies suggests ten rolls per one area. Using two different derma rollers to try and stimulate hair growth can also be effective. The difference in the rollers will be the size of the needles. For example, as previously mentioned, the most common needle size to use in a derma roller is 1.5 mm. However, evidence has shown that using rollers with different sized needles may help speed up the hair growth process.

Needles vary from 0.15 mm, 0.25 mm, 0.50 mm, 0.75 mm, 1.0 mm, and 1.5 mm. The derma rollers with smaller needles are known to help penetrate the scalp at the proper depth. Whereas derma rollers with longer needles are designed to penetrate the scalp at a deeper level to boost cell production and

prevent hair loss.

How Often Should You Use a Derma Roller?

This varies depending on the size of needle. It is recommended when using a smaller needle less than 0.5 mm, complete the treatment every other day, depending on your pain tolerance.

When using a longer needle size of approximately 1.5 mm, complete the treatment about once every week. Depending on one’s tolerance the amount of treatments may change. With a lower pain tolerance try applying less pressure when rolling the derma roller over the scalp. It’s important not to cause unbearable pain throughout this process.
