DHT blocker can be an effective way to stop hair loss.

Science has struggled for decades to better understand the biological cause of hair loss. It is not an easy question, but nowadays we can answer it confidently. It is widely accepted that, in 95% of cases, hair loss is caused by a substance called Dihydrotestosterone – commonly referred to as DHT.

A powerful metabolite which occurs naturally in the human body, and the largest cause of hair loss in men and women alike. DHT is very important for men in early ages, as it’s necessary to develop certain male characteristics such as facial hair. Over time, it becomes less essential but still plays a role in your hormonal balance.

Role of DHT

Dihydrotestosterone is present in the body of all people and is actually very useful. It is crucial in the sexual development of males. It is very similar to testosterone and is synthesised more during puberty where it is responsible for changes in voice facial hair and reproductive development.

As we age we still maintain a small need for DHT but some individuals become sensitive and it starts to act inconvenient ways.

DHT and hair loss

Cause of Any Hair Loss

For decades scientists have struggled to find out the biological causes of hair loss and until recently this proved extremely difficult as there are several types of hair loss and seemingly just as many cause for each type.

It is important to establish the cause of any hair loss, as this will determine the next steps in terms of treatment or management.

While there is no method to fully reverse baldness as yet, it can be managed in different ways.

If hair loss occurs suddenly, the cause may be medical and it is important to see your doctor. Some types of hair loss can be an indication of a stress, nutritional deficiencies or using the incorrect hair products. A simple blood test may be able to find any reasons and also improve the diet and eating healthy will improve hair growth.

The Most Common Cause Of  Hair Loss

The main cause of pattern hair loss (baldness in men and women) is Androgenic Alopecia. It is 95% of all cases. Responsible for AA is the androgens testosterone and DHT (dihydrotestosterone). => source

Now that science better understand what causes hair loss. It becomes much easier to treat.

Over time, however, DHT tends to inhibit the hair growth ability of the follicles. Some people are not affected by it in the scalp, but individuals with a genetic tendency to hair loss are sensitive to DHT’s effects.

Several pharmaceutical companies who produce hair loss products claim this function.

However as technology and research methods have improved it has become clear that most forms of hair loss may follow a similar route and a common components is DHT

How DHT Affects Hair Growth

DHT tends to inhibit the hair growth ability of the follicles by acting as competition for receptor space instead of behaving as a sex hormone. Some people are not affected by it presence in the scalp, but individuals with a genetic tendency to hair loss are sensitive to DHT’s effects.

When a DHT sensitive individual does not protect themselves, the substance will damage hair follicles, which will begin to produce less and thinner hair, until it stops producing any hair at all.

This explains the gradual loss of hair that occurs with Androgenic Alopecia and can occur over several decades starting as early as the end of teenage years.

Basically the process consists of DHT attaching itself to receptor cells in the hair follicles, preventing vitamin, minerals and proteins from reaching them. Without these important nourishing substances, the follicles slowly become unable to sustain life, shrinking in size.

Of course, the miniaturization of the follicles will cause hair to grow at a slower and slower rate, either lengthening the resting stage or shortening the growing phase. The hair shaft becomes thinner with each growth cycle, until hair stops emerging.

This change can be permanent once the follicles reach a certain size however most will still produce some hair which may resemble vellus hair (covers most of the body) or the hair cycles becomes so long that they seem dormant.


How Can You Prevent Hair Loss Caused By DHT?

While leading a stress-free life and maintaining proper nutrition are important steps that’ll help with hair loss, they aren’t likely to be enough, as DHT occurs naturally in the body and some individuals are sensitive to it.

Instead, to prevent DHT-induced hair loss, it is best to use a DHT blocking product.

In general, there are 4 ways to effectively block DHT and prevent hair loss. Products usually have one of these effects, or a combination of them:

1. Reducing DHT production in the body.

2. Inhibiting the production of 5 alpha reductase – the enzyme which converts testosterone into DHT.

3. Reducing substances that produce said enzyme, such as cholesterol.

4. Preventing DHT from attaching to the hair follicles‘ receptors.

Any product that achieves one or more of these goals can be considered a DHT-blocker, and if it manages to do that effectively, it will prevent hair loss to varying degrees.

These products are known as DHT blocker, and they can work in a variety of ways

How to choose the Best DHT Blocker to stop hair loss

Our Recommeded List of DHT Blockers

1. Finasteride (the only one approved by FDA)

The best known dht blocker. It is taken in pill form (internally) and works to inhibit the enzyme 5 alpha reductase. 1mg of Finasteride is enough to achieve results. 5mg is used for enlarged prostat. Finasteride can decrease serum levels of DHT by up to 70%. => study

Generic Name: finasteride

Brand Names: Propecia (1mg Finasteride), Proscar (5mg Finasteride), Durasterid, Avocar


Patients who had problems with an enlarged prostate and also had hair loss experienced treatment with Proscar in addition to significantly reducing prostate problems, stopping hair loss and increasing new hair.


Following this discovery, Merck immediately started a clinical study to evaluate the efficacy of finasteride in the treatment of hair loss when taken as a tablet. To minimize side effects, Merck reduced the dose of finasteride to 1 mg and conducted a series of clinical studies.

In the first 5-year clinical study, 352 patients at different stages of hair loss were involved. At the start of the study, the researchers calculated the number of hairs in the monitored hairy circular area of ​​the scalp with a diameter of 2.5 cm. The average hair count of patients in this area was 876 hair. Two groups of patients were created to compare the effects of finasteride. One group was taking a 1 mg tablet of finasteride. The second group was taking a placebo tablet without finasteride or any other active substance.

After the first year of treatment, patients receiving finasteride had an average of 126 hair more than patients receiving placebo. This difference in the number of hairs in the observed circular area of ​​the scalp gradually increased.

By the end of the fifth year of treatment, patients receiving finasteride had 277 hair more than patients receiving placebo. Up to 65% of patients receiving finasteride retained or improved their original hair count in the study area compared to the hair count at baseline. All patients who received placebo had a reduced hair count.

Side Effects

In the first 12-month phase of the study, the following adverse reactions were reported in a small group of patients: decreased libido, difficulty achieving an erection, and reduced ejaculate volume. These adverse reactions gradually disappeared in all patients who stopped treatment, but also in 56% of patients who continued treatment until the end of the fifth year.

By researching and testing, Merck has demonstrated the potential of finasteride to stop male hair loss and to induce new hair growth.

In December 1997, based on research results, the United States Department of Health and Human Services (HHS) approved Propecia (finasteride 1mg) as effective in the use of the US Food and Drug Administration (FDA). treating male hair loss.

Unlike minoxidil which can treat both male and female pattern hair loss, Finasteride is only effective with males. This success rates for commercially viable hair growth even after 6 months of treatment is around 25%. Aside from low success rates it is the preferred choice as the side effects are milder and less common.

The characteristics include a general thinning if the top of the hair from hairline to crown. Unlike men the area will not become bald. Will be very sparse and the hair will look see through making the scalp easily viewable.

As women tend to experience this type of hair loss in smaller numbers and at a higher age most of the research and products are aimed at men.

Many women will use other means to disguise the hair loss rather than seeking treatment. They are more likely to seek advice solely from their hairdressers who would probably suggest a new hair colour, cut or even wigs.
