I had some thinning of my hair so I tried the pantene full and thick and pantene sheer volume, at first I thought it really made a difference, then I started to notice that my hair was getting thinner. After making some inquiries I was told my more than one hairdresser that Pantene was the worst thing I could use on my hair. The hairdressers I talked to had been taught this in Cosomatology School. The reason for this is Pantene builds up on your hair and eventually causes it to fall out. I had to purchase a rather expensive hair treatment to try to reverse the damage Pantene has done to my hair. I am in the process of gathering documentation of others who have also had hair loss due to this product. When I called the medical lline from Pantene they told me they couldnt belive this caused my hair loss. More than one of the hairdressers I spoke with are giving me written statements to verify the imformation they gave me.
