hi tim i have just read your pm. sorry i did not know about that earlier it is not alerted.
i will try to answer your questions.
i will give you history. i started to loss hair minimal at the front when i was about nineteen twenty. i was very distressed like most people. just the lose at the front took a lot of my looks and confidence. i tried minox it worked however it itched so i would scratch out the benefits. when i did not scratch it did grow the hair at the front it was downy hair unfortunately. i tried xandrox which reduced loss quite a lot but it is expensive it also did not regrow hair. i would not advise it on a budget.
about two three years ago i started to thin at the back. this was distressing it is was a spot at first and the last year or two it got to a patch thinner near the vertex and less in the middle. i tried foam in late 2008 and instantly it grew back the majority of lost hair at the front within two weeks it was dark almost full but a bit thinner. like i said if i used it three or four times a day it was faster and thicker so you might want to try that at first. also the foam is cheaper than minox liquid because it lasts longer apart from kirkland which is cheap but slightly less affective (note only slightly so if you are on a budget might be worth it).
anyway i got the laser comb a few years ago when the back started to thin. i did not use it properly so i did not think it worked (this is common i think). i followed the instructions for a week or two and it did not work so i stopped. anyway i started using the foam on the back when i started using on the front it shed so it thinned a lot and it went near to bald people to me. then still on the foam at the back it thickened up all apart from a small area so then i tried retinoic acid (don't) with the foam it made a lot of it fall out. so then i went back to the foam and i got worried (badly probably like what you feel, like checking it all the time and being really self conscious etc) so then i thought what about the laser comb why did some say it worked and others not. i got the old one out and had a look at what the light looked like. i beamed it on my finger and it has little red splogges like when you see a picture of the sun i looked closely (do it yourself) and i thought this is different to other light i have seen this is doing something i don't know what but it is.
then i decided to use it properly with the foam. within the first time of using my hair was better. then within two to three days i could feel fuz on the scalp and two weeks later you could not see the scalp. i kept it up with the foam for three weeks to a month and went to have my hair cut. this was the first time in months from concern about loss. my hairdresser said it had filled in. so i got complacent and did not every other day and brushed through it not holding it in one place. so then i started again without foam on the back about ten days ago it worked again so i posted to help others. i also take zinc every day. it is as a result of the laser comb though.
in relation to where i got the comb i got it about three years ago on the internet from hairmax sellers. i don't know now. but i have seen alternatives for half the price. a hairmax in england it about £200 maybe £300 i have seen others for £129 £150.
other names are velform, proxtra, x5, neolight.
i don't know if the others work but i think they would. i assume you live in america so i do not know. interestingly they do a proxtra helmet in america at amazon for $100 - $200. some links.
there are a couple for just over $100 dollars. you usually get a return period so if it doesn't work you can get your money back. the proxtra looks good but i can only witness the hairmax. also the hairmax i have is the cheapest hairmax so you don't have to get the most expensive one.
i will stay on the forums for a while to see responses and i will try to get a picture but i have to get a camera.
