This is one of the best hair products lines I have ever used. (and being older and having my hair colored every color over the years and permed too, I have used most all of them!)I recently got a permanent on double processed hair (bleached blonde) because I was told it would be ok --it definitely WAS NOT and it fried my hair. So I went in search of MANY products in attempt to correct the situation; from the usual over the counter stuff to going to the beauty supply store; and this little quest was starting to cost some serious money, and not correcting anything!! Oh, they would work for awhile, but by midday we were back to looking dry. So my stepdaughter called one of the big hair product companies in New York (after a bad perm she had gotten) and they told her Biosilk. She told me she had purchased this from the hair salon in her local Walmart. ( I was immediately skeptical) But vanity overcomes fear and I went to ours and purchased this stuff. Lo and behold, it WORKED!!! Needless to say I was very happy - since I even bought it half off regular price! ( I was used to buying Paul Mitchell products and I thought they were expensive)But now I stock up when it is on sale and I really do love the entire line! I would recommend this to anyone!
