Now, I have tried it once...everything seems okay BUT the only thing I do not like is that after using it my hair looks kindda dull....I mean I have straight shinny hair....after my 1st wash with this system they look matte :p
I think that is coz of all the chemicals....
yea Nioxin does that too the hair, and it is because of all the chemicals...thats why u might have to stop using it for a little while and thn start again (or else it will just dry out ur hair)...
good luck!
