Microneedling, if used correctly, may stimulate the hair follicle to produce stronger and thicker hair and regrow hair from dormant follicles.
According to one study from 2013 the base line hair count changed with 91 hairs/cm2 in a group patients treated with Microneedling and Minoxidil while the patients using only Minoxidil had a hair count increase of 22.2 hairs/cm2 from baseline.
The effect of Micro-needling is believed to be due to a number of reasons, including the release of growth factors from the platelets. The activation of platelets also increase the release of epidermal growth factors and stimulate skin regeneration.
The trauma caused by Microneedling activates stem cells in the bulge area of the hair follicle as part of the wound repair and skin healing processes.
Further, Microneedling also causes the expression of hair growth related genes such as B catenin, Wnt3a and Wnt10b
Skin repair and healing after a trauma to the skin is a very complex process. Despite massive research we do not have a 100% understanding of what exactly happens. The role or stimulation of the hair follicle during a controlled trauma is also not fully established.
M-PRP for hair loss
We recommend using Microneedling in combination with Platelet Rich Plasma when treating hair loss. As the scalp is already anaesthetised for Microneedling, the addition of PRP to the treatment is really very easy. M-PRP takes slightly longer than Microneedling alone.
Is Microneedling for hair loss painful?
Before the actual Microneedling starts a local anaesthetics is applied. While the local anaesthetics is applied you may feel some discomfort. The skin is then anaesthetised and you’ll not feel any discomfort during the actual Microneedling. The process takes around 30-45 minutes depending on the area that is being covered. In case of M-PRP the process takes around one hour.
Complications and downtime after Microneedling for hair loss
After Microneedling or M-PRP for hair loss you are physically able to carry on with your normal daily routine. There really is not downtime with this hair loss procedure, though you might want to take it easy for the rest of the day. However, this is not required.
Some patients may experience tenderness or tightness in the scalp after the procedure. If this is the case, then paracetamol is usually sufficient.
