Can I Have Platelet Rich Plasma Therapy Instead of Hair Transplant Surgery?

Q: It was recommended by the doctor that I have a hair transplant. Could I do platelet rich plasma (PRP) instead?

A: PRP will generally be inadequate for patients who are candidates for a hair transplant. PRP works to reverse (thinning hair) as do other medical treatments (Propecia, Rogaine, LLLT). Unfortunately, medical treatments do not grow hair back once it has been lost.

New Research Shows Laser Therapy (LLLT) is an Effective Treatment for Male and Female Pattern Hair Loss

Given the large number of people who are affected by androgenetic alopecia and for whom traditional treatments, like surgical hair restoration or hair loss medications, may not be indicated, could low-level laser therapy be a viable and effective treatment option? New research published this year, 2014, in the American Journal of Clinical Dermatology, says yes.

Do You Recommend Azelaic Acid With Rogaine (Minoxidil) 2% Or 5%?

Q: Have you any experience with Azelaic Acid as a hair loss treatment — is this something you would recommend using with Rogaine (minoxidil) 2% or 5% solutions?

A: Azeleic acid has no direct benefit in promoting hair growth. Azelaic acid (like retinoic acid) increases the absorption of minoxidil, but also the side effects, so I would especially not recommend it in your case.

Does Propecia (Finasteride) Work Long-Term?

Q: I have been taking finasteride for several years and I seem to be doing well. Does finasteride generally work long-term?

A: With regard to efficacy, a recent long-term, uncontrolled study by Rossi et al. reported that the effects of finasteride were not reduced as time goes on and that a significant proportion of patients, unchanged after 1 year, improved later on. In addition these patients maintained a positive trend over time -– up to ten years. When comparing different age groups, they found that subjects older than 30 years showed a better hair growth in the long term than those who were younger. Of the 113 patients in the study followed for 10 years, only 14% worsened, whereas the remaining 86% had benefits.

Should I Start Hair Loss Treatment With Finasteride or Dutasteride?

Q: I recently visited my dermatologist regarding my hair loss, and after checking my hair he said I am showing signs of [Androgenetic Alopecia (AGA)], and said if I don’t treat it, it will progress. From my research on the net, I figured he will put me on Propecia. In fact he put me on Avodart. When I told him it is not FDA-approved for hair loss, and Propecia is, he said Avodart is better and brings DHT down more, and Propecia is nothing next to Avodart. He told me to take it every day for 2 weeks, then every other day from then on as it has a long half life. From researching on the net, many hair restoration doctors, rarely prescribe Avodart for hair loss due to some dangers. What is your opinion on this?

A: Although dutasteride (Avodart) can be more effective for male pattern hair loss, I would start with finasteride (Propecia) as many patients do great with it and the safety profile is better. The following are things I would consider before starting dutasteride:

  1. As you point out, dutasteride is not FDA-approved for hair loss.
  2. There is no data on its safety when used for hair loss. This is important since dutasteride has been only tested on an older population of patients (with prostate disease) rather than a younger population of patients needing medical treatment for androgenetic alopecia.
  3. These is no natural model for dutasteride’s combined blockage of both type 1 and 2 5-alpha reductase (finasteride blocks only type 2 5-AR and there are families that have this deficiency and have no long-term problems. This, by the way, is how the drug was discovered).
  4. The type 1 enzyme which dutasteride blocks is present in many more tissues of the body (including the brain) compared to type 2 (which is more localized to the skin).
  5. Although so far unproven, there is a concern that finasteride may produce side effects than can be persistent after stopping the medication (post-finasteride syndrome). It this does turn out to be true, the effects from dutasteride would most likely be significantly more persistent.
  6. If you start with finasteride and do have side effects, you will most surely have side effects from dutasteride; therefore, by taking finasteride first you will have avoided the potentially more problematic side effects from dutasteride
  7. You may respond well to finasteride, and so do not need to consider dutasteride

Propecia Causes No Statistically Significant Change in Sexual Function, Says 2004 Tosti Study

The central finding of a 2004 study led by Italian researcher Dr. Antonella Tosti, in which he and his team investigated sexual dysfunction in hair loss patients being treated for androgenetic alopecia, was that there was no statistically significant change in sexual function after four to six months of treatment with finasteride 1mg (Propecia).

Interestingly, the research team found that sexual side effects were actually less common than reported in the clinical trials of the drug.

Before and After Photos of Medical Therapy Look Too Good To Be True!

Q: Are the “result” photos from taking Propecia and using Rogaine legitimate? Some of the after photos look too good to be real and a few patients looked like they combed their hair to look like they had more coverage.

A: The before and after photos of patients using Propecia and Rogaine are my patients. All photos on our website are un-retouched. Often, when patients have a good response to medical therapy, they have more flexibility in how they can groom and style their hair. This is reflected in the photos.

Persistent Side Effects From Propecia

Q: You prescribed Propecia for my hair loss. I was wondering if the new news report on Propecia side effects has altered your opinion regarding the safety of this drug?

A: It has not changed. I believe you are referring to Dr. Michael Irwig’s study at George Washington University published in the Journal of Sexual Medicine. I was already aware of the study when I prescribed the medication for you and we discussed the risk of persistent side effects at your consult.

Although all types of data should be considered, it is important to realize that this was not a scientific study, but a survey. It had very significant selection bias. From this type of study, one can’t prove cause and effect relationships or even get a sense of actual incidences. These were patients who were recruited because they already had persistent sexual dysfunction. Since it is not clear if their persistent problems were directly due to the medication or from other factors, and since these patients were selected, rather than randomly assigned, the additional information can be gained from the report is very limited.

That said, the reporting of persistent side effects should not be taken lightly, but should be viewed in the context of all available data. It is extremely important for us to continue to be vigilant, as this is a very significant issue, but it is equally important not to make decisions on data sensationalized in the media. As a result of the finasteride data, some are presenting surgery as a more reasonable alternative than medication. For a young person, that is usually not the case.
