laser comb
I posted an answer but it didn't come through, so here goes another one. I think the laser comb has stimulated my hair and kept it in healing mode through all the stuff I put on my scalp over the years. If you look at the photos of newly transplanted scalps where laser comb has been used on one side only, you can see the increased healing and new growth on the laser side. Cold beam laser will not hurt your hair, only help keep it alive while waiting for minoxidil, etc., to go through their cycles of fallout and regrowth and, we hope, eventually save the hair. It also has been shown to regrow hair on its own. I think the company is responsive and honest and I've been using their product for almost four years. I'm still struggling hard against my genes and I go through nasty sheds all the time. I have stubborn thinning at the crown and all over the top, and my hairline comes and goes, but I'm not bald yet like my brother and my dad were in their twenties, and I'm going to keep fighting this thing. I've just gotton on finasteride and I've already gone through an initial shot of regrowth and shedding, which is also a minoxidil effect, but I'm hanging in, using the comb and tricomin, and I'm not giving up.
On the subject of stress and hair loss, I'm convinced it plays a part in speeding it up, and I'm working on not letting this get to me. Like some of the guys have said, you play the hand you're dealt.
