I have mid length dyed blonde/silver hair. Its very thick and can go a bit wavy and frizzy after washing if I dont straighten it, I only wash my hair once a week so its not abused too much! After I had it coloured last time the hairdresser put this paste through my wet hair then dried it straight after, I forgot to ask what it was but think it was to tame the frizz and protect it a bit. Does anyone have any idea what it could be? Or recommend anything? Tia
