Best DHT Blocker Vitamins – Our Detailed List
Here’s the detailed version of the best DHT blocker vitamins hair loss experts recommend shortlist:
#9. Vitamin B7 (Biotin)

Vitamin B7, also known as biotin. A member of the B vitamin family that helps our body’s enzymes to break down fats and proteins in the foods that we intake.
As a hair loss treatment, biotin promotes keratin production and can increase the rate of hair follicle growth.
People generally use it to boost hair growth. But furthermore, vitamin B7 can strengthen hair making you less prone to hair fall, especially for people with biotin deficiency problems.
#8. Vitamin B9 (Folic Acid)

Vitamin B9, better known as folic acid, plays a significant role in biochemical processes in the human body. They are primarily responsible for the regeneration, metabolism, and healthy growth of cells in different parts of the body, including our hair.
They are also an essential nutrient that promotes DNA development, which is why it is commonly prescribed supplements for pregnant women.
Its ability to encourage cell growth and DNA repair help to battle against hair loss, at the same time, promotes hair growth for fuller and thicker hair.
#7. Selenium

Selenium is a trace mineral known as an antioxidant with immunomodulatory effects. As an antioxidant, they help to protect skin and other organs from cellular damage, as well as in our hair.
Interestingly, they also play a role in our hair keratinization process that supports hair growth and combat hair loss. In fact, according to some studies, although rare, selenium deficiency could even cause hair thinning and baldness.
Taking selenium, combined with zinc, can be beneficial to your body, not only as immune support but also for thicker and long lasting healthy hair.
#6. Vitamin E

Vitamin E is a nutrient that can be found in numerous food sources as well as in supplement form. Its antioxidant properties reduce cell damage, promote healthy hair growth and support other DHT-blocking nutrients in your body.
That is why many skin and hair growth products include this as one of the main ingredients in their compounds.
With its natural antioxidant effects, vitamin E may help support a healthy scalp by reducing the amount of oxidative stress and free radicals that can cause hair follicles of men and women to break down.
#5. Vitamin A

What is the fastest-growing tissue in your body? That’s right, it is your hair!
Vitamin A, also known as retinol, is vital for your cells to grow, which, in turn, encourages healthy hair growth. This vitamin also aids in the production of sebum oil in the hair follicles, which helps our scalp moisturize and protect it from harmful bacteria.
This hair growth supplement is widely used in different hair loss products today. But you must be aware that taking too much vitamin A can also cause thinning hair and even baldness.
#4. Collagen

Do you know that collagen is the most abundant protein you can find inside your body? Yes, this collagen helps make up ligaments, tendons, and skin.
But this can also provide other health benefits, such as delaying hair loss and promoting hair growth.
Collagen can provide amino acids, which are very important for the hair life cycle. These amino acids are building blocks that are needed to produce keratin, the protein in our body that makes hair.
It also acts as a natural DHT blocker and an antioxidant that prevents damage in our hair follicles caused by unwanted free radicals in our system.
#3. Vitamin B3 (Niacin)

Vitamin B3, popularly known as niacin, is a micronutrient that our body uses for the function of our nervous system, proper metabolism, and healthy skin.
Niacin has long been used as a hair-loss supplement and is commonly used as an ingredient for shampoos and conditioners. It improves blood circulation in our scalps which aids in the stimulation of hair growth to prevent thinning hair.
This DHT blocker has anti-inflammatory properties that prevent hair loss due to inflammation caused by elevated DHT levels, which is why it is often used in hair loss treatment products.
#2. Zinc

Zinc is also one of the essential nutrients that our body needs to keep us healthy. It aids our immune system in protecting our body against harmful bacteria and viruses.
When it comes to hair loss, zinc plays a major role in our hair health, as this mineral is responsible for hair tissue repair and growth. Additionally, it ensures that the oil glands around the follicles function properly and seamlessly.
It also works as a DHT blocker by keeping the level of DHT in our body from getting too high, and some research even says that men with a low level of zinc are more susceptible to having male pattern hair loss.
#1. Magnesium

Here is a little trivia for you. Do you know that almost 80% of American people are magnesium deficient? Sad to say, but that is the truth. And sometimes, magnesium deficiency manifests in various ways, such as hair loss.
But what is magnesium anyway?
Magnesium is an essential nutrient for many bodily functions, including nerve function, regulating muscle, and making body proteins and bones.
It is responsible for maintaining hair follicles anchored in our scalp to prevent hair loss and encourage maximum hair growth. Moreover, this nutrient maintains hormonal balance in our body, making it an excellent DHT blocker that can be used by men and women.
What Is DHT?
Dihydrotestosterone (DHT) is a hormone that plays a key role in sexual development. It helps give men their male characteristics, such as a deep voice, muscle mass, and body hair.
When these DHT levels are too low or too high, it may cause different issues that can affect your body, including your prostate health and hair loss. If you are concerned about your DHT levels, talk with your doctor. They may order a blood test and advise treatments that could help.
How Does DHT Cause Hair Loss?
There are many reasons for you to experience hair loss, and one of them might be because of a high level of DHT in your body.
Too much DHT could result in hair thinning as this hormone shrinks hair follicles and shortens their life cycle. This hormone is one of the most common culprits that cause male pattern baldness.
