I know Klorane makes clarifying and oily hair shampoos also, just wondering if anyone with greasehead like me had any luck using this?I'm blonde also.

Be of good cheer. I had to wash my hair every day for decades because I had such greasy hair (and skin). I heard all my life that people with greasy hair didn't go grey early. Hurray! I am in my late sixties and still have my shiny dark honey blonde hair with NO grey. Chamomile shampoo helps keep it shiny and I like Klorane the best.

Why does it say “SLS free” if it’s right on the second ingredient?

You are right. Sodium lauryl sulfate (SLS) is the second ingredient on their products. They should not be able to day SLS free. The US manufacturer on Amazon here says free of Sulfates again in brief product description after Klorane description. You can tell their English is bad, perhaps they have no idea what SLS even is????? Ha!

el champú es especial para cabellos rubios? aclara mas el cabello? se puede usar en bebes?

No te aclara más, si no te conserva el color rubio, y si usan en bebes

Has anybody used this for Henna hair? If so, did it have any affect on the color?

My daughter used in her natural Blond color and this shampoo keep the color and you can see a kind of highlights, so probably in henna hair could work better(I guess)
