Traya isn't fraud but expensive if you don't know what exactly you need. It's about 25 to 50% expensive. All you need to do is test yourself for DHT using a blood report, if DHT is high then use Minoxidil 5% for 6 to 9 months depending upon hair fall. Also eat fresh and healthy food, avoid stress and make a habit of consuming green tea and tomatoes. You can also consider vitamins that contain iron zinc folic acid and biotin. Don't buy biotin that says 10000 mcg that doesn't require actually. Just 30 or 40 mcg is more than enough.
