## Description

Stephen Knoll New York Deep Treatment Hair Mask is an at-home deep treatment that brings out the natural beauty of hair from the first application, making it the ideal solution for dry, damaged and over-processed hair. The mask penetrates into the hair in minutes, reinvigorating and repairing it, strand by strand. Helping to fortify and restore the health of the hair, the unique formula rehydrates and protects the strands from external damage, while enhancing retention. Deep Treatment Hair Mask incorporates two key ingredients to leave hair soft and more manageable: Shea Butter and Hydrolized Wheat Protein.

## Features

- This exclusive formulation works deeply into the hair core, reinvigorating and repairing strand by strand, without weighing down or leaving your hair greasy.
- Deep Treatment Hair Mask intensely nourishes you hair, leaving it improved texture, more body, and easy to manage and with luminous shine.
- With Deep Treatment Hair Mask you only need 5 minutes (7 at the most) to have soft and lustrous hair without seeing your hairstylist.
- The formula is extremely rich, so a little less than a tablespoon of product is enough for an average amount of hair."
- Made in Japan

    Stay away!
  

*by A***Y on Reviewed in the United States on April 24, 2012*

If you look At the ingredients on the label It's full of chemicals that harm your hair. The silky smooth feeling is just a temporary result of the petroleum which locks out moisture with long term use. I found this article helpful: [...] I'm not sure how accurate it is, but why take the risk?

### ⭐⭐⭐⭐⭐ 







  
  
    Excellent Treatment for Brittle Dry Hair
  

*by K***L on Reviewed in the United States on October 17, 2014*

My husbands hair is colored long and thinning. It gets brittle and has splitends from hats and weather. Been using this product on his hair  every 120days with a solid coating (cover the entire hair generously and leave it onfor hours or overnight) and it helps keep his hair moist. All hair andmake ups have chemicals in them, some good some bad. This producthas not caused any further damage and has improved his hair's longevity.This is the last of this one because they changed it to another design.I will try this one as long as I can. 7 were available I am taking 4 of the 7 justto help you all with the bargain price.
