The Dr Nettles Story

"At a young age, I saw first my father, then older brothers thin, then bald. Deducing a similar future for myself, I started researching genetic inheritance patterns and DNA, later training in hair transplant surgery, including working alongside pioneers of the FUE method. I soon realized that transplants do not stop the progress of hair loss, 

I had an AHA moment when discovering that just as we now know good and bad types of cholesterol, so testosterone also has good and bad components, and the ratio between them would lead to my ultimate discovery of precision medicine."

To the left you can see the Nettles family tree, or at least the five Nettles brothers from oldest to youngest. Unluckily for the oldest three Dr Nettles did not discover the cure until it was too late for them. As you can see both Robert and his younger brother (Robert is the second youngest) sport a full head of hair despite both now being well beyond the age when their father and older brothers had already lost their hair. 

Why Stop and reGrow?

Dr Nettles Story

Dr Nettles was a hair loss sufferer himself and spent the last 25 years researching and developing this revolutionary treatment.

Healthy Hair Education

por Dr Robert Nettles 07 sep, 2017

Which hair loss treatment is right for you?  Do they all really work?  Lets take a look at the most popular ones and the requirements for a hair loss treatment which really works to both stop hair loss and regrow thin/receding hair.

The first thing to understand is that the number one cause of hair loss is Androgenetic Alopecia. We do see other types of hair loss in our practice of course, however 95% of cases we see include at least a component of Androgenetic Alopecia as well.

The hair loss in Androgenetic Alopecia is caused by high levels of DHT.  50% of men and 25% of women are born with a hereditary gene which causes them to over-produce DHT which then binds to the hair shaft in hereditable patterns and gradually suffocate the hair causing it to miniaturize over time and eventually die. In order to stop hair loss we therefore must stop this process from occurring. We then need to grow back the damaged hair. Without doing both of these 2 things any hair loss treatment will be ineffective.

Now let’s look at each of the available treatments on the market and see how they shape up.

Rogaine/Minoxidil  - entered the market in 1988 as the first medication which grows hair. Minoxidil is a vasodilator that works to increase blood flow to the scalp with the original idea being that if the hair follicles receive more nutrients from the extra blood flow they would regrow. Rogaine does produce slight hair growth in about 20% of people and which was later discovered to be a result of mild anagen antagonist qualities of Minoxidil rather than from the additional blood flow originally thought. Anagen antagonists speed up the catagen/resting phase of the hair and cause new hair to turn over more quickly and to grow back slightly thicker than the previous one. Whilst minoxidil may in fact assist some people with hair growth, the problem is that it doesn’t also stop the hair loss and the DHT will continue is binding to the hair shaft which will eventually overtake any additional growth caused by the Minoxidil and die, perhaps just slightly later than it would have without the Minoxidil. The alcohol base required to support the active ingredients also cause irritation of the scalp and sever reactions for many people.

Propecia  - 9 years later in 1997, Propecia/Proscar/Finasteride was launched as the first pill to stop hair loss by blocking DHT. Whilst Propecia does do as promised and block DHT, it has a number of problems associated with it:

  1. It has a very short half-life of only 6 hours which means it is working in our system for only part of the day and as a result causes swings in hormone levels that lead to side effects for many people.
  2. There have been a myriad of reported side effects when this medicine is taken orally and in a one size fits all dose. America’s one size fits all approach to medicines causes a lot of problems for people, but you can read more about that in my previous article on personalized medicine  .
  3. It does not regrow hair. And especially because it is not working in your body 24 hours per day, it does not even give the hair a chance to regrow effectively on its own.

Laser Comb/Cap  - HairMax launched the initial and most widely used laser hair comb back in 2001. The way these combs work is by using red light to stimulate cell regeneration and growth.The regime required to support this requires regular use for at least 15 minutes at a time.  Even if their claims of hair growth stimulation are true, just like with Minoxidil, eventually the DHT will completely block the hair follicle from being able to absorb nutrients no matter how much growth stimulation they receive and will eventually be overtaken by hair loss and no longer be effective.

Supplements  - Hair supplements, vitamins and dietary improvements have been around for many years and have been growing in popularity recently, especially with Dr Oz promoting Phytoceramides. Like the laser comb, many of these can be effective where the cause of hair loss is poor nutrition only.  We see this in less than 1% of cases. So again, while providing the hair with better nutrition can help androgenetic alopecia minimally for a short while, it will not be able to overcome the effects of DHT.

Hair Transplant  – Hair transplants were first pioneered back in the 1050's but have come a very long way since then. The new robotic single hair transplant methods available today are definitely the way to go if this is something you need. My goal however is to prevent you from ever needing one. The problem with them is that they are expensive, ranging generally from $10,000 to $30,000 depending on the surgeon and method. They also won’t solve your hair loss problem long term. It is likely you will need at least 3 to 4 of them unless you are also able to stop the initial cause of hair loss.  We see many clients who have had their first transplant and then come to us distraught as they continue to lose hair around and behind the transplant location. Another important point about transplants is that transplants will never provide you with the thickness of hair you once had because every hair you transplant cuts off blood supply to the 4-6 immediately around them. You cannot transplant them as close together as your hair would naturally grow.

PRP  - PRP, Plasma and Stem Cell therapy are much more recent additions to the hair regrowth treatment options available. And by now you should be able to tell yourself that these too are not going to be able to prevent hair loss long term but only assist with hair growth. Each of them in their individual way works to stimulate new cell generation and growth. However, as you now know, unless you stop your cause of hair loss, the follicle will eventually again be overloaded with DHT and unable to survive. Where these treatments have been especially successful is in assisting transplanted hair follicles to “take” in their newly transplanted location so that your “take rate” of transplanted hairs is improved.

Shampoos & Non-Prescription Topicals   - Shampoos like Keranique and others have gained a lot of publicity lately.  They claim to have a proprietary blend of ingredients that block DHT and regrow hair.  None of their ingredients (unless they also contain Minoxidil) are FDA approved to grow hair.  And as they are not prescription medicines they cannot penetrate the scalp and make any difference.  One thing to note is that an FDA approved manufacturing lab is certified as clean and safe, it does not mean anything manufactured within it actually works.

Some other facts to be aware of when assessing any hair loss treatment you may come across are as follows:

1.      Any product or treatment which penetrates the skin and changes the internal composition of the body (ie: like blocking or reducing DHT) is required by law to be available only by prescription and must be regulated by the FDA.

2.      Only FDA approved products are held to standard of TRUTH in their claims and advertising. Any product which is not approved by the FDA can make any claims they like about what they do without fear of sanction. Basically they can lie about their effectiveness and no-one will check on what they are saying. There are many shampoos for example which cannot possibly block DHT as they do not penetrate the skin which claim to stop hair loss but receive no sanction and are not tested to verify their claims.

Stop and reGrow is comprised of FDA Approved active ingredients which have been rigorously tested and clinically proven to both stop hair loss and regrow thin hair.

Precision medicine is a paradigm-shifting model of medicine that “ensures delivery of the right intervention to the right patient at the right time.”  It has gained a significant amount of attention in the past decade, and over $215 million was invested  into an American health initiative that sought to bring precision medicine into many different fields of healthcare.

However, this doesn’t answer the question of how it stacks up to the traditional “Big Pharma” approach to medicine. Therefore, it’s important to do a thorough comparison of both medical models to assess which one is superior.


The “Big Pharma” approach is driven by a ‘one size fits all’ mentality where treatments are based on what works for the population on average  . This means that two patients could be drastically different from each other, and yet receive the same medical treatment.

The medications created within this model are designed to sit on the shelf. In other words, they can be held in storage for a very long time without decaying or rotting away. Adding special preservatives into the medications is what allows them to have such a long shelf life.

It is also worth mentioning that medications in the “Big Pharma” model are ‘single-purpose’ – they are made to treat a single disease/condition, and are not designed to be used in combination with other medications to achieve a different outcome.



With that being said, there are definitely similarities that exist between “Big Pharma” and “precision medicine”. For starters, medications in both models are regulated at the state level and the federal level. This allows for companies and scientists to rapidly innovate and develop ground-breaking treatments without breaking any rules regarding health, safety and over-exaggerated claims.

In both models, safe and effective active ingredients are used to create the treatments given to patients. They both provide patients with the care they need, but the question ultimately boils down to which model does the better job of treating patients on an individual level.



Precision medicine is based on your biochemistry. What does this mean? It means that your lifestyle, genetics, environment, age, sex, race, treatment history and other personal factors are all taken into account when deciding on the perfect treatment strategy that delivers the best outcome possible. Here’s an easy way to put it: We give different dosages (i.e. amount of medicine) to kids than we do adults, due to significant differences in height and weight.

Precision medicine argues that we need to factor in those same differences when we deal with adults. In fact, given that we are currently experiencing the greatest disparity in height and weight in recorded history  , the personalized dosing provided by precision medicine is starting to become the better choice for patients. People need to get the dose that is ‘just right’ for the personally, and avoid paying extra for anything they do not need.

Also, precision medicine focuses on combination-purpose treatments where multiple medications might be used as part of a single treatment. For example, in Stop & ReGrowTM, our innovative hair loss solution, a combination of medicines are used to stimulate hair growth and prevent hair loss at the same time. A single-purpose medication would only achieve one of those two goals.

Additionally, there are no GMOs (genetically modified organisms) or preservatives used in precision medicine treatments. Therefore, precision medicine is the optimal choice for people who are worried about the possible negative health effects (ex. Organ damage) that may come about from consuming too many GMOs and pesticides  .



While the “Big Pharma” model served its use in the healthcare industry for several decades, precision medicine is proving to be the logically superior choice for creative the most effective medical treatments. You end up with a fully customized solution that works just for you, and eliminates the possibility of side effects or problems related to overdosing.

Give us a call today at (310) 601-4778  to schedule your consultation. You’ll learn how precision medicine can help you improve your health and become the best possible version of yourself – the way nature intended you to be.

Before and Afters

“I have been Seeing Dr. Nettles for 9 months and I am blown away with results! I was shopping around for a Transplant when I met him and so glad I did. Completely stopped the Hair loss and it's growing back like a weed. 
I love how he got Blood work on me and figured my unique situation for hair loss. He told me more about my health than my real Doctor!
I work in the Beauty Industry and have been turning many of the stylists I know on to him. Everyone Loves him and all I have referred is also blown away with their results and how honest and affordable he is.
My hair stylist can't believe the results and has started referring her clients."
“I have been researching hair loss and I've gone to several doctors to see what I can do about my thinning hair. After visiting dr. Nettles office, from my experience, what he showed me and the information and the process that's required to keep my existing hair and to have a chance of regrowing new hair made so much more sense than any other doctors for me. His way of looking at this situation and the before and after of existing clients convinced me to start the treatment with him. So far it has been an amazing experience and the office staff are very courteous, helpful and have been following up with me. I highly recommend this office for anyone who has thinning hair problems..”
