Science_d you keep advising people to use the Laser Cap but why? How can lasers regrow hair? What's the science behind it? What official study has shown its effectiveness? I had 20 minutes to pass so I skimmed down through around 200 amazon reviews about it and nearly everyone basically said it was utterly useless. There were 5 or 6 who said the quality of their hair seemed to slightly improve but those 5 or 6 were probably using other methods to improve their hair. I think the only thing it does effectively is pry money from desperate people and leave them disappointed.
I am only reporting what the scientific studies I have seen have demonstrated. The following peer-reviewed studies have shown that low-level lasers seem to have an effect on hair growth:
http://onlinelibrary.wiley.com/doi/10.1111/dsu.12200/abstract
http://www.ncbi.nlm.nih.gov/pubmed/23970445
http://online.liebertpub.com/doi/abs/10.1089/153082003769591209
From a review of the literature, one paper concluded that LLLT devices do have some effectiveness (
http://www.ncbi.nlm.nih.gov/pubmed/26690359).
Thus, I am only reporting what those scientific studies have reported. If you are aware of studies showing that low-level lasers had no measurable effect on hair growth, or problems with the methodology of the above studies, I would definitely be interested in seeing them.
In my experience, the 80-laser Theradome device was
not effective for me, at least as far as affecting hair
density. So I would probably not recommend it to anyone experiencing aggressive hair loss. However, when I used a 272-diode laser cap plus minoxidil for about 4 - 6 months, I definitely experienced positive effects. Does this mean it was due to the low-level laser? I don't know. It is possible that was the minoxidil. However, it is also
possible that it was the combined effect of the laser and the minoxidil. Once again, I don't know. I am interested in testing the 272-diode laser cap alone on myself to see if has positive effects.
As far as the reviews you looked at, you might have been looking at an 80-diode device such as the Theradome. Once again, that is consistent with my experience. I had no significant positive benefit from that device, so I would agree with the negative reviews of that device. However, it is
inconclusive whether or not the more powerful, 272-diode laser was effective for me or not.
Again, I am only advising the Laser Cap as a
possible treatment based on the studies that have been done, and the fact that I may have benefited from it myself (
https://attackplan.wordpress.com/category/my-personal-experience/). Some hair restoration doctors, such as Dr. Alan Bauman, recommend it for their patients. Does that mean it is valid? Not necessarily, but it is worth noting that some board-certified hair restoration doctors do recommend it.
I am a firm believer of not wasting money on questionable treatments, which is why on my blog I encourage people to only use treatments whose effectiveness have been established by research (
https://attackplan.wordpress.com/2015/09/21/skeptical/). If you read all of my posts on this forum, you will see that I discourage or downplay any treatment if there is no peer-reviewed paper supporting its effectiveness for male pattern baldness. And I will certainly not promote laser therapy if someone shows me evidence that it isn't effective.
Is low-level laser therapy effective? Some scientific studies seem to suggest that, and my personal experience may confirm that. However, I am definitely open to changing my mind if I don't see evidence for it. Also, if someone tries a laser device for 6 months with no positive benefits, I would certainly not recommend they continue using it.
As I state on my blog:
"If there are no studies showing [a treatment's] effectiveness, it is probably a waste of money. I discuss many of these products on my website here, along with links to various studies
, so you can decide for yourself what might be worth using or not" (
