New Technique - Scalp Micro-Pigmentation (SMP)

Posted on 17 Feb, 2017

Female Hair Loss ScarA new technique called Scalp Micro-Pigmentation has recently been developed that has an exciting future in the range of therapies that we can offer for hair loss or patients with scarring of the scalp.

The idea of using a pigment tattoo to help camouflage scars on the scalp is not new. The problem with previous techniques is that the tattoo faded to blue or green over time and the pigment often “bled” into surrounding skin to give a “paint” effect which was not natural. Recently however, the development of newer, non-metallic pigments, together with the development of a specific technique to place pigment dots into the middle layers of the skin has revolutionised the concept.  The use of non-metallic pigments is crucial as it will allow patients to have MRI scans if they are needed.

The outcome of the SMP technique is to produce the appearance of shaved hairs. This can be applied to any scarring of the scalp with matching of pigment colour to natural hair colour. This means any patient with donor scars from previous hair transplant surgery may achieve good camouflage of the scar with this technique.  In most patients the SMP will last from 2-4 years before needing a refresh.

In addition, women suffering from Female Androgenetic Alopecia (Female Pattern Hair Loss) can have the illusion of extra density created by providing SMP to the upper scalp. This eliminates the need for topical camouflage products which need to be constantly used.

The Knudsen Clinic is proud to announce that SMP will be available from mid-2017 at our Hair Clinics.

What is Platelet Rich Plasma (PRP)?

Posted on 11 May, 2016

There has been a lot of publicity in recent times about a possible new treatment for hair loss (of any cause) that is called Platelet Rich Plasma (PRP). This is argued to be a “stimulation” therapy for hair loss. The theory is that the multiple skin growth factors that live inside platelets (the blood cells responsible for clotting) can be utilised to stimulate hair by “cracking open” the platelets after the patient’s own blood has been centrifuged (spun down). These growth factors are then re-injected into the scalp in areas of thinning hair.

The idea has been around for a while but the evidence for hair stimulation has not been strong. We do know that PRP is helpful with wound healing but it is less clear which thinning patients might benefit. One of the problems is that the technique has no stringent set of rules and different centrifuges produce different results. Current research is directed at assessing whether higher concentrations of growth factors produce a stronger stimulating effect on weakened hairs.

Another possible line of research involves combing PRP with an extracellular matrix product that acts as a scaffold to assist the effect of the growth factors. Further research is needed in this area.

At best, current evidence is inconclusive that PRP is as effective as other stimulatory products such as minoxidil or techniques such as low level laser therapy.
