I have just started my third bottle (month 3) of volyoume spray. The product itself is easy to use, sprays well and does not have any odour which is quite nice. I use a scalp massager to rub it in which I would recommend to make sure it gets to the scalp. I have not yet noticed a difference but I am being patient and trusting the process and will continue the product for now. I have been experiencing hair loss due to weight loss.
