Kevin's Tips: I’ve worked with women of all ages, with all hair types, and by far the most emotionally devastating ‘hair’ issue I’ve seen is hair loss/thinning. I decided to create a product that would add volume plus help to densify and strengthen the hair. Using scientifically proven eyelash plumping technology, we created BODY.MASS, the final step in our THICKENING regimen. Used alongside PLUMPING.WASH and RINSE and as part of our THICKENING regimen, our leave-in plumping treatment will create plumper, thicker-looking hair. You’ll notice instant cosmetic thickening, and over time you’ll see a noticeable difference in hair quality – Try it for 14 days, and the results will speak for themselves.
