DHT & Your Hair: Everything you need to know about the #1 Hair loss culprit (and 3 proven treatments to block it) in 2026. If you find yourself noticeing the sides of your temple slowly retract, the top of your head starts to spread and you’ve ever muttered under your breath…
“Is it because I’m going bald?
The good news is, you’re right on the mark; with 95% probability, the hair loss offender is the notorious hormone – Dihydrotestosterone (DHT).
We know, we know – the name probably comes up every time this topic of conversation starts, but do you actually know what this hormone actually does?
Is DHT BAD for us?
Will having testosterone ensure you end up bald, or is it a little bit more complicated than that? And can you effectively block DHT, without ultimately turning yourself into a ‘girl’ (and we’ll put that phrasing into perspective, too).
At Evolved Hair Restoration we always feel you should get all the facts.
So here’s exactly what is going on between DHT and the hair follicles on your head.
What Is Dihydrotestosterone?
DHT is a highly powerful sex hormone the technically has the name ‘androgen’.
Throughout human history, and even in fetal stages – this hormone is key in developing characteristic that are associated with becoming a male: from those deepened tones to the actual growth of body and hair hair! DHT is produced from the non-bound free T that we circulate in our bloodstream. Roughly 10 percent of a day’s supply of the testosterone you have circulating in your blood becomes converted by a cellular enzyme to 5 alpha-reductase, also known as DHT.
Why Does DHT cause hair loss?
(It has nothing to do with high testosterone) This is one of the biggest misconceptions associated with male pattern hair loss. We do not go bald just because we have high circulating T – a high amount of men who are losing hair actually have normal levels or below average levels of T. What determines whether we have pattern baldness is not necessarily how much T we are producing, or even how concentrated ourDHT is, but rather the receptors within our individual hair follicles and how they are reacting to this particular hormone. Why then is it that the hair on some parts of the head remains whilst others shed?
You might wonder, if I am balding on the sides of my head, why haven’t my hair follicles at the sides of the head been effected?
Frontal and the crowns of your hair – the sensitive areas! The hair follicles that are at the back of your head at the crown region have very specific androgen receptors. These receptors respond readily to circulating T (which is why they grow at the side of your head), but due to their increased sensitivity in some males.
With the presence of DHT these AR’s will respond to this change by inducing miniaturisation – a process that results in the hair on top of the head to become shorter, finer and weaker, eventually making them undetectable. • back of the scalp or side – the unaffected ones! Contrary to their more sensitive counterparts on top of the head, the hair follicles that reside at the very front or sides of the head have highly insensitive DHT receptors. This means they are completely immune to any changes brought on by your hormones, this includes those you see when transplanting your hair; a transplant taken from the donor site at the back of the head remains unaffected from DHT.
How to Block DHT – the cutting edge hair treatments in 2026 To prevent hair miniaturization, we must find methods of interrupting how DHT communicates with its corresponding receptors found on the follicles:
1: Type II 5- alpha-reductase inhibitors This class of medication inhibits the activity of the Type II enzyme found within the hair follicle.
A low, daily 1 milligram dosage of this form of prescription medicine will help halt all hair loss/thinning – even in severely balding men (where ~85% of hair can be regrown / prevented, with proper usage).
2: Dual 5- alpha-reductase inhibitors Similar to the ones above but both the Type I & II of the 5-alpha-reductase enzyme, blocking this one more effectively than the Type II alone. Type I & II blockers are generally prescribed for those men for whom Type II has had no real impact or for men experiencing severe balding. They affect all the T hormone circulation throughout the entire body.
3: Topical antiandrogen/ receptor blocking treatments This is where a whole new generation of hair restoration solutions comes into play that we all hear about!
These solutions will directly block DHT from binding to those hair follicle receptors without causing any circulating hormones to affect either sexual health or muscle mass. This is relatively new and research continues, however many men have had fantastic success and in some cases have noticed hair regrowth.
4: Other botanicals & topical scalp treatments (These are more of a supplementary/supportive roll).
Ketoconazole 2% shampoo Research has revealed that a frequent usage of a Ketoconazole shampoo (at a concentration of 2%) will slow down the hair loss/ thinning at your crown. There have been few studies that hint that there might be a benefit in the hair growth of balding men when using this shampoo. Natural therapies- These can be useful, but don’t have the same robust clinical evidence behind them.
Some, such asSaw Palmetto, while popular, are not the best options for you.
DoBlocking DHT Will Impair My “Masculinity,” Muscle Mass or Sex Drive? Of course, this might be your most crucial question. What we are experiencing is common but fortunately there are many myths surrounding the effects blocking DHT has. Read on for the honest information.
It’s T that fuel your muscle – DHT has minimal role in this.
You will notice increases in circulating free T when you take a DHT blockers because the body does not get an opportunity to metabolize this into 5- alpha-reductase. Your free T could increase by about 10-15 %. The vast majority of users will find no affect on their sex drive / libido – however, between 1.5 – 3 % experience very minor effects.
Taking action The ultimate secret is to do something – If you choose to turn a blind eye to the fact that you have a genetic predisposition towards hair loss, than in turn you can expect to continue seeing the hair thinning over a more aggressive period. By taking proactive measures towards blocking DHT you significantly increase your chances of retaining your natural hair and reducing the need to visit a surgeon just for a transplant in the years to come.
