By using pregnenolone cream or pregnenolone supplements, the levels of the compound in the body increases, and this brings about various benefits such as fatigue relief, and delay of the aging process.

What blocks DHT? When people ask that, the first thing that usually comes to mind is Finasteride.

It’s one of the most popular modern remedies to treat receding hairlines. The downside? Finasteride is a synthetic DHT blocker, and it has its side effects.

Many men are looking for natural alternatives, and that's the focus of this short guide. Today, we will cover all the most effective options to help you find a natural (and effective) DHT blocker without nasty downsides.

What is DHT and What Are Its Functions?

Dihydrotestosterone (DHT) is a type of androgen, a male sex hormone. DHT is naturally produced in the human body and is primarily responsible for forming the physical characteristics we typically see in males.

Sounds good, right? So why would anyone want to block DHT?

Experts believe that DHT is responsible for making the hair follicles on the head to shrink. When the hair follicles become smaller, this results in slower hair growth and eventual baldness.

That's why there are so many clinical studies that focus on what blocks DHT in the scalp. Also, keep in mind DHT affects not only men, but women too.

Studies estimate that up to 50% of men will experience male-pattern hair loss due to overproduction of DHT by the age of 50.

Remember that DHT isn't essentially a bad hormone. In fact, as an androgen it's responsible for producing the characteristic male traits in the body.

In all fairness, DHT is crucial for male health. What researchers are interested in is blocking the excess of this hormone that happens to men and women later in life.

Some of these researchers strongly suggest that treatments with caffeine in their formula are very effective.
