I am 25 and have bald head. Very bad hairfall in last 3-4 years. I was not sure about the reason behind this. My father also had got bald head during his teenage, this is the only reason I could think of at this moment in time. I am using hair for sure and couldn't comment on its performance as it has been 3 weeks since I started using this. Could you please help me to understand the reason for hairfall. How to tackle this and precautionary measures at least from now. Also pls help me to understand if HAIR FOR SURE works? Are there any adverse effects in using HAIR FOR SURE TONIC? If this tonic is of no use, could you suggest any other medicine or tonic that I can use to prevent this. Pls help. Thanks in advance.
