Does low level laser therapy inhibit 5AR?

can someone read through that and let me know? i can’t really understand

@Northern_Star @Greek @borax

" Weiss and coworkers, by using RT-PCR and microarray analysis, demonstrated that depending on the treatment parameters, LLLT modulates 5-α reductase expression, which converts testosterone into DHT, alters vascular endothelial growth factor gene expression as wells as matrix metalloproteinase (MMP-2) which have significant roles in hair follicle growth, and in turn the group reported stimulation of hair growth on human dermal papillae cells [4447]."

Seems like you got your answer.

It also seems to me that attempting to prevent / halt hairloss is probably a terrible idea for people signed up here.

Right but that part means it inhibits it?

Says modulate but not really grasping that meaning

From what I understand the low level laser therapy acts more as a vasodilator and allows blood flow to folllicles, rather than interfering with DHT.
I’ve been using one the last couple of years since I dropped finasteride .


But what’s the interpretation of that study where it says “modulates 5ar”

Doesn’t that imply inhibition?

The definition of modulates is ‘exert a modifying or controlling influence on ‘ …couldn’t say for sure what it does!

I’ve been using a red light cap for 8+ months now without any issues. However, interesting find there!

Thanks. You also seem to think it implies that it inhibits 5ar?

I’d like to see the specific study they are drawing this conclusion from, I couldn’t find the full study it refers to. Key phrase in there is as well is “depending on the treatment parameters”.
