Love, love, love. I have been experiencing thinning hair for a variety of hormonal and stress related reasons. I had been using another phyto product but had been going through a bottle in less than a month - for $34 a bottle that was way too much. I thought I would give this a try and have been super pleased. I find considerably less hair falling out and my hair just looks healthier. I know that some have commented on the smell and while I do find there is a certain pine odor I don't think it's bad enough to stop using. I know that some say they leave it in overnight but I have never tried that. I put it in as soon as I get up in the morning and let it sit for 20 mins while I have morning coffee. Since I only do it once a week I don't think its a problem with my morning routine.
