Revivogen, the wonder hair loss product that has been formulated by Dr. Alex Khadavi, using the natural ingredients works both in preventing the thinning of the hair and in enhancing the growth of healthier hair. It is able to achieve this by effectively binding the hormone DHT that are present in the scalp which cause the thinning and the subsequent loss of hair. Revivogen has to be directly applied on the head or in patches where predominant hair loss is seen, at least once in a day. The dosage could be tapered off after about six months, to 3 or 4 times a week.
