The Real Cause of Hair Loss Can’t Be DHT...

Let's Get Hair

Have we been lied to about hair loss? If testosterone drops as we age, why do we keep losing more hair? In this video I break down why "DHT theory makes no sense" is a trick, and what really decides whether your follicles survive.

Bold of you to assume I kept my hair in my 20s

Another common misunderstanding related to this: "why does balding get worse as we get older if its DHT?" Well, it doesn't. Balding is the process. If you have less hair at 50 than 40, that doesn't mean the balding is worse. Time has simply gone on.

Transplanted hair eventually falls out if you don't take finasteride. I suspect the act of wounding the scalp during the hair transplant may also reverse some of the fibrosis, similar to dermarolling. Scalp tension is the most likely root cause of male pattern hairloss.

I think DHT for AGA is the same as LDL cholesterol for atherosclwrosis. They happen to be at the scene of the crime and their action is causing some damage but truly they are there to prevent a bigger damage from happening.

I do everything, finasteride oral, minoxidil topical, scalp massage manually, red light cap if there is no sun, microneedling, fixed gut/inflammation/nutrition/avoiding toxins/lost fat/working out, reduced ejaculation amounts for potential less prolactin levels.
The thing that does pretty much everything is finasteride but I’m getting really good results as a 2,5 Norwood and will complete it with a hair transplant next summer.

Nice video Matt, What's your current hair loss protocol?

the root cause is inflamation. The whole skull is inflamed. And one of the main cause is food, then stress which spikes cortisol and cortisol generates inflamation.

Nobody has ever proven that one particular follicle is more sensitive to dht than another. "Genetics" is a convenient reason when someone doesn't understand the mechanism at work. DHT levels are higher in the top of the scalp as a result of inflammation as a result of chronic tension. The body responds by building scar tissue which cuts off blood supply.

Its because the damage caused by DHT is cumulative. DHT is damaging everyone's hair since puberty, it's just that for some, this damage manifests as miniaturization at 15, whereas for others it can start at 40. When this will happen is determined by genetics, of course.

Your logic is flawed if DHT is cause then Dut should almost completely stop MPB. That would mean a 98% effective rate and men in their 80's would have a hairline of a 25 year old. I challenge anyone to show me what I've said is factually incorrect

Good video. I disagree with you on scalp tension though. Scalp tension increases 5AR and DHT. That's why botox works (I've tried it). The best way to deal with hair loss is to tackle scalp tension and reduce DHT. I learnt this Rob English 2017 paper: A hypothetical pathogenesis model for androgenic alopecia.

It depends on the case. In my case, finasteride is just a miracle for my head.

Give him 2,3 years Finasteride and forget

Showing a picture Elon Musk is meaningless, all we know is he has had a HT at some point in his life and no idea how many in total and when it was done. I've had six done over a 20 year period and with 100% certainty transplanted hair has disappeared and that is with fin and midox
