Microneedling for Hair Loss

Hair loss can be caused by a number of factors such as stress, psoriasis, alopecia etc. Depending on the cause, microneedling can be an effective treatment to lessen or prevent hair loss.

How does microneedling work?

Microneedling comes in several forms including stamping, roller and automated pen systems. Generally the pen systems are preferred as the depth, speed and needle size is fully customisable and is not dependant on the therapists use. Derma Rollers can be used on a small depth to resurface the skin, however on a deeper depth these can cause trauma to the skin by creating a bigger incision with the roller technique.
When used on the scalp the needle size is generally recommended to be between 1.5 – 2mm depth, this is safest as a pen system or stamp when used by a professional.

Microneedling is a controlled injury which encourages the body to create a response which includes the production of collagen.  A randomized controlled trial performed in India highlights how using microneedling produces better results than treating your hair loss with Minoxidil. Minoxidil is currently one of the most effective topical treatments out there. As such, the study’s results are very promising.

Does Microneedling work for Hair Loss?

Depending on the underlying cause of the hair loss, microneedling can be an ideal treatment. If the hair loss stems from stress, psoriasis, seborrheic dermatisis it can still be treated but treatment for underlying cause may also be needed. Those suffering from androgenic alopecia, though, should consider microneedling. In addition to the studies cited above, further research from the same team demonstrates how the procedure leads to denser and stronger scalp follicles. These follicles produce healthier hair, making microneedling worth the effort. While the aforementioned study highlights microneedling’s efficacy through strengthening scalp follicles, other areas of research have discovered the specific chemical pathways behind its success. For example, a study published in Annals of Dermatology found that it activates the Wnt/β-catenin pathway, which is a signal-conducting pathway that allows cells to work and communicate with each other. It also promotes expression of VEGF, which is vascular endothelial growth factor. In other words, more blood vessels will develop in the area, allowing for the delivery of oxygen and removal of toxins which is vital for hair growth.

Does Microneedling hurt?

Although microneedling is a minimally invasive procedure, it is still targeting the epidermis which can have a nerve response, however it is very minimal. If any pain is felt, it is very short lived and will be gone within a few hours post treatment.

How many treatments are needed?

How many treatments you need varies, everyone’s response to the treatment is different, we recommend doing a treatment every week for 6 weeks and then once a month for a following 6 months. However treatments can be done when required and top up sessions can be down to the patients response to the treatment.
