The DHT blocker vitamins from Kiierr uses horsetail extract, vitamin B6, folic acid, and saw palmetto to block DHT. The supplement also includes nettle to prevent hereditary hair loss.

The way this product slows hair loss is by reducing the conversion of testosterone into DHT. Based on studies from the American Hair Loss Association, saw palmetto is very effective in lowering your DHT levels.

Furthermore, this supplement blocks the enzyme 5-alpha-reductase (5AR) to reduce DHT. Blocking the 5AR enzyme is the natural way to block DHT unlike other expensive and dangerous treatments.

In addition to saw palmetto being a DHT blocker, it also produces sterols and fatty acids. This prevents buildup on your scalp which can clog hair follicles from growing naturally.

Buying Tips On How To Choose A DHT Blocker Supplement

After going through hundreds of supplements. We have come up with a rough process on how to investigate and filter products when choosing a DHT blocker supplement.

Below are a few tips when buying a supplement.

Consult Medical Professionals

First and foremost, go talk to your PCP or a medical professional first. This is especially important if you are taking other drugs for your health. You want to watch out for adverse reactions.

Types of the professional you can speak to include a dermatologist, trichologist, or a pharmacist.

Types of Ingredients

When you shop for a hair growth supplement, it is important to read the label. As obvious as this is.

It is annoying and we know the pain since we have to read through everything when we were testing each of these individual DHT blocker supplements.

But, just like you wouldn’t want to marry someone without dating first, you should be familiar with what is in hair growth vitamins as well.

Ingredient Serving Amount

Most hair growth vitamins are water-soluble. However, some are not.

Therefore, make sure you don’t take too much all at one. Otherwise you may risk becoming sick.

A good rule of thumb is to start with the recommended dosage. Then scale up based on your body’s feeling. More is not better in most cases.

As always consult with your medical professional first.

Product Safety

Lastly, even when you look at the label of each supplement. Do you read all the details including the fine print?

For example, do the brands you are looking at have Good Manufacturing Practices (GMP)? 

Other questions to ask yourself are the following.

  • Are the DHT blockers manufactured in the USA?
  • Does the DHT blocker have any certifications?
  • Are there any allergy triggers in the hair growth supplement?

It’s difficult to ever trust a DHT blocker fully because the FDA does not regulate hair growth vitamins and supplements.

You need to be careful, no matter how many positive reviews a DHT blocker has received. That is why we highlight the problems and benefits for each product we review.

Frequently Asked Questions

What Does DHT Do To Your Hair?

DHT is a hormone that’s responsible for many things in the body, including hair growth. When it comes to hair, DHT is thought to be one of the main culprits behind hair loss. 

DHT stands for dihydrotestosterone, and it’s a metabolite of testosterone. And when testosterone is converted into DHT, it can shrink hair follicles. 

This may not sound like a big deal, but when hair follicles shrink, they produce thinner, finer hairs (a.k.a. androgenetic alopecia). So, in short, DHT can cause your once thick and luscious locks to become wispy and weak. 

Does Blocking DHT Regrow Hair?

There is no one definitive answer to this question as there is still much unknown about the role of DHT in hair loss. However, there are several possible ways that blocking DHT could help to regrow hair.

One theory is that DHT shrinks hair follicles, which makes them less able to produce new hairs. Blocking DHT could therefore help to restore hair growth by reversing this shrinkage. 

Another possibility is that DHT triggers a process called miniaturization, which causes hairs to become smaller and weaker until they eventually disappear. Blocking DHT could halt or reverse this process, leading to thicker and healthier hair growth.

Are DHT Blockers Bad For You?

There is some debate over whether or not DHT blockers are bad for you. The main concern seems to be that by inhibiting the conversion of testosterone to DHT, you might also be inhibiting the production of testosterone.

However, if you are taking a DHT blocker for a specific medical reason (such as hair loss), then it is important to follow your doctor’s instructions on how to take it. 

In general, it is best to only take a DHT blocker as prescribed by a doctor, and avoid taking them if you do not have a medical condition that requires them.
