for loseing hair

some friend told his experience bout losing hair...he'd been at some experts but still no happen..but somebody advised him to try dove soap (dove soap user too) as to his hair just for a week..and see if it is effective or what will happen...then he say's it is good, less hair fall,..so y don't you try it too...currently am using head and shoulder too..and it is good for me..no hair fall, no dandruff...very good
