Part 3. Exercise
The formulation of this product has been changed since Artec was bought by L'Oreal. The new formula doesn't hold hair like the old Artec original formula did, and it doesn't smell as nice. Don't be fooled by this picture (12/29/07)--it is a pic of the old Artec bottle, but I ordered and received the new L'Oreal Professionel version, which is terrible. The original Artec version was similar to, but not as sticky as, Potion 9. I wish L'Oreal would go back to the old formula :( I emailed them to this effect and they never even replied. If anyone can recommend a similar product, please comment to this review.
Answer:
Negative
