Hair loss reversal & laser therapy: fact or fallacy?

Daniella Rialas, Trichologist at Hadley Wood Healthcare

I recently attended our annual seminar hosted by The Institute of Trichologists last week that was held at the Wella World Studio.

The key note presentation was given by Dr Hugh Rushton DSc PhD, presented the findings of: The effect of laser hair comb therapy in male pattern hair loss: A six months half-head blinded study.

Over the last 20 years various treatments for male pattern hair loss (MPHL), mostly from charlatans and without proof of efficacy,have been suggested. Two therapies however, finasteride and minoxidil, have stood the test of time and been shown to improve different aspects of the balding process. Laser induced hair growth in MPHL has been advocated and recently one double blind randomised placebo controlled study (RCT) has been published. However, in this report there are some concerns about the unexplained exclusion of subjects in an RCT employing Intention To Treat analysis.

Two male subjects exhibiting MPHL were measured for the fundamental hair variables: length, density, diameter, linear growth, percent of ansgen, and exogen hair collection employing validated and established methologies:- the unit area trichogram and contrast-enhanced-phototrichiogram. The result of this six-months, half-headed, blinded study will be presented.

Until the results of the above study get published I will remain sceptical whether such treatment as laser therapy works.

If you want to discuss any aspect of hair health or are worried about hair loss please call me at Hadley Wood Healthcare on 0208 441 8352 or email me direct at My Trichology web page can be found here.
