Hair and Now

Posted on 10 Oct, 2013

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.

Low Level Laser Therapy Hair Loss

Finasteride and Prostate Cancer

Posted on 09 Sep, 2013

A long-running study of men in the USA with enlarged non-cancerous prostates (benign prostatic hyperplasia – BPH) using finasteride previously reported a 25% reduction in overall numbers of patients developing prostate cancer. However, there was some debate about whether the prostate cancers detected in users of finasteride were of the more aggressive variety. A recent analysis of this study showed that finasteride users had lower levels of the prostate cancer screening test PSA (prostate specific antigen) which led to more accurate diagnosis of those patients actually suffering cancer rather than just an enlarged prostate. In addition, the smaller prostates made tumour detection easier by biopsy.

 

Overall, men taking finasteride were 30% less likely to be diagnosed with prostate cancer and 43% less likely to get a diagnosis of low-grade cancer (slow growing). In addition, survival rates were not changed in patients taking finasteride compared to those not on finasteride.This is very reassuring news to patients taking finasteride for hair loss as these prostate effects are beneficial rather than harmful and will likely result in less unnecessary surgical treatment of prostate enlargement in future. We can reassure patients talking finasteride that there are no harmful long-term effects on the prostate from treating their hair loss.

Natural Ingredients for Hair Loss

Posted on 21 Jul, 2013

I frequently get asked the question: Are there any “natural” products I can use for my hair loss? The answer is – it depends upon the cause of the hair loss.

 

For example, if the hair loss is related to iron deficiency anaemia, then foods with high iron content or iron tablets could help. Biotin (Vitamin H) deficiency has been correlated with hair loss but it is a very unusual cause in the general population. Vitamin H, Vitamin B6 and zinc are all essential nutrients for healthy hair but are not necessarily involved in a particular persons hair loss, so supplementing them may not be effective.

 

That said, products like Provillus that contain them, and saw palmetto, are not going to harm anyone suffering from hair loss. The unfortunate assumption is that these “natural” remedies, essential for healthy hair, are helpful in the commonest forms of hair loss in men and women: male pattern baldness and female pattern hair loss. There is NO evidence that these nutrients are involved in these conditions and therefore NO evidence they assist in balding or female pattern thinning.

Hair Loss myths

Posted on 05 Jul, 2013

Tight hats make your hair fall out.

 

Not true. Tight hats might restrict blood supply to the scalp but only by a minimal amount. Whatever the cause of hair loss, hats have no effect on the condition.

 

Too strong a shampoo causes hair loss.

 

Not true. Shampoo is merely a soap for cleaning the hair shaft and has no effect upon hair growth. The hair growth cells are 3-4 mm under the skin and cannot be affected by ordinary shampoos or conditioners.

Shaving your hair makes it grow back stronger.

Not true. As your hair grows it becomes subject to environmental damage (wind, sunlight, washing and combing or scratching). The result of this is that the tips of the hairs become tapered over time. If the tip of the hair frays you get a “split end”.

When you shave hairs and feel the stubble coming back, these hairs have not suffered environmental damage and feel quite “thick”.

They are just normal hairs without damage.
