Review title is Hair Saver! [SEP] When I went through chemotherapy, I lost most of my hair, and as a woman this was a real blow to my self image. This trio of products was recommended to me by the woman who runs our local health food store, and along with taking an oral biotin supplement (5,000 mcg per day), I used this three-step system (shampoo, conditioner, and leave-in serum) to wash and condition my hair. Between the two approaches, both oral and topical, I re-grew all of my original hair, and now my hairdresser swears that I have more hair now than I did before I was diagnosed with cancer and went through chemotherapy.  It does feel thicker to me now, too, and my husband has also remarked that my hair has never looked better.<br /><br />The only caveat is that if you have longer hair you may need an extra conditioner for the ends. Otherwise, I would highly recommend this product (plus oral biotin supplements) to anyone who has had hair loss due to chemotherapy.  I was very satisfied with the results.  Minus one star only because the conditioner doesn't work quite as well on longer hair, but it is more important that you apply this product to the scalp, so again you can use a more silky conditioner for the ends.
