I have been using mine for about two months and I just ordered and received a bottle of the scented to go with my unscented. Initally, I was having problems with the scent-I could smell the sulfur and it was much worse when I worked out or was in the sun. I added some jasmin oil and problem solved. I was also seeing hair strands after using it, more than before. It has since stopped.
The good--My hair has really grown. I have Lupus and some times I get scalp sores and the BT seems to heal them and keep new ones from appearing (at least so far). Also, I had Lupus alopecia (bald spots), two for almost a year now with no hair growth. I applied the BT almost every day for the last two months to those spots and it has grown about an inch and a have. It is baby fine but there and growing. Finally, it is the first product that DH agrees has really made my hair grow. He encouraged me to by another bottle and told me it should be purchased just like my prescriptions.
Sorry so long but, I'm a believer!!!!
